Morgan Hoffmann was spinning his wheels after two rounds at the HP Byron Nelson Championship. Even-par for the tournament heading into the weekend, the PGA TOUR rookie made a mid-tournament putter change that turned the weekend into a successful one for the 23-year-old. 

"The ball striking was great the whole week," Hoffmann said on Sunday afternoon. "The first two days I literally didn't make one putt. I switched after the second day, so it worked out after that."

Hoffmann started the week with a Scotty Cameron GoLo putter before going back to an old Scotty Cameron Newport. The 23-year-old shot 66-66 (8-under) over the weekend with the putter to post his first top-5 finish on the PGA TOUR. 

Dufner switches putters again: Struggling with his speed on the greens this season, Jason Dufner switched to a Scotty Cameron Futura X Prototype putter for the last two rounds of the Zurich Classic of New Orleans, and THE PLAYERS Championship. 

On Tuesday, Dufner was spotted working with another putter -- a Scotty Cameron GSS Circa 62 No. 6 prototype, which happened to be the same model he used to win last year's HP Byron Nelson Championship. Dufner went back to the putter in hopes of finding his putting stroke. 

Colored backline helps Gonzales' putting: Using a custom Odyssey Versa (black-white-black) #2 Longneck putter for the first time in competition, Andres Gonzales felt it needed something extra to remind him where the center of the putter face was. 

To help him out, Odyssey added red paint to the backline to give Gonzales the visible reminder her was looking for. Gonzales said he aims the new putter better than his old Odyssey White Hot #6 Longneck. 

Day testing new iron shafts: Jason Day made noise early in the week when he put a custom TaylorMade RocketBladez Tour 1-iron in play at the HP Byron Nelson Championship. 

Instead of going with his standard True Temper Rifle 6.5 shaft in the iron, Day tried out a UST Mamiya Recoil 125 F5(X) shaft and liked it enough to have a whole set of RocketBladez Tour irons built with the same shafts to test in the coming weeks.

Oosthuizen tests PING G25 fairway woods: Louis Oosthuizen has changed most of his equipment over the last few years, but his PING G5 fairway woods (3- and 5-wood) have remained in the bag.

Even though Oosthuizen had the fairway woods in play at the HP Byron Nelson Championship, he started testing a PING G25 3- and 5-wood with a Mitsubishi Diamana 'ahina shaft (70x in the 3-wood and 80x in the 5-wood). Oosthuizen put the same shaft (60x) in his PING Anser driver at THE PLAYERS Championship.

Adams sets hybrid record at HP Byron Nelson Championship: According to Adams Golf, the company set a new PGA TOUR record with 59 hybrids in play at the HP Byron Nelson Championship. Equipment counts rarely register on a week-to-week basis, however, the figure was more than double Adams' next closest competitor.  

Guan Tianlang gets additional yards with different iron setup: You're never too young (or old) to try out new golf equipment — especially if it can help you get a few extra yards. Take Guan Tianlang, for instance. The 14-year-old tested out UST's Recoil shafts — heavier weighted graphite shafts — in his irons and wedges and gained 7-8 yards with the new setup.

Divots: Ben Kohles felt his Titleist 913D3 (8.5 degrees) was spinning too much, so Titleist Tour reps built him a 7.5-degree 913D3 that was 44 inches instead of 44.5. The shorter shaft and lower loft combination allowed Kohles to reduce the spin coming off the driver face. ... Chris DiMarco changed shafts in his PING G25 driver, going from a Project X 6.5 to a Fujikura Speeded 6.2x. ... Justin Hicks became the latest player to switch into TaylorMade's Daddy Long Legs counterbalanced putter. ... A season-best 12 players put Adams Golf's DHy driving iron in play, including Marcel Siem (T-33). ... Looking for extra bite with his wedges, Charl Schwartzel put a new set of Nike VR Pro wedges (47, 54, 59 degrees) with fresh grooves in the bag. ... Scott Langley tried out a UST VTS 6x Red shaft in his PING G25 driver. ... Steven Bowditch (2-iron) and Cameron Percy (3-iron) had Cleveland 588 TT long-irons built.

The putter Al Geiberger used to shoot the first 59 recorded on the PGA TOUR is staying in the PING Golf family. Last month, Geiberger auctioned off a large portion of his golf memorabilia through Green Jacket Auctions, including the clubs, putter and hat he wore during the historic round at the 1977 Memphis Classic.

While it's unclear who bought the clubs and hat, PING confirmed the PING Pal putter was already back at the company's headquarters in Phoenix, Ariz., after it was purchased for $7,222.

The putter will be displayed outside PING Chairman & CEO John Solheim's office in a trophy case alongside several other clubs, including a gold-plated version of Bubba Watson's Tour-S wedge (the wedge he used to hit the winning shot from the trees at the 2012 Masters), Louis Oosthuizen's S56 4-iron, and a replica of Angel Cabrera's i-Series 1/2 Craz-E putter from the 2009 Masters.

IRVING, Texas -- Growing up in the Houston area, Shawn Stefani loved playing baseball as a kid, particularly catcher. But as an athlete, he was more talented on the golf course than the baseball diamond.

This week at the HP Byron Nelson Championship, the PGA TOUR rookie started a business relationship that allows him to combine the two sports.

Stefani signed a sponsorship deal that puts the MLB.com logo on his bag for the rest of the year. MLB.com is the official web site of Major League Baseball, and Stefani is the first golfer they've sponsored.

"As a brand, it's a good idea to associate me with MLB.com," Stefani said.

The relationship grew out of a conversation Stefani's agent, Dave Parker, had in February at the Waste Management Phoenix Open with a marketing representative from MLB.com. The two just happened to be sitting at the same table at a corporate event and began discussing ideas.

Their suggestions were then presented to Bob Bowman, the chief executive officer of MLB Advanced Media.

"It happened real quick," Parker said. "Bob loves golf and attends many events. We were just looking for a way to do some cross-promotion."

Although Stefani is just on his first full year on TOUR and is still finding his way -- he ranks 144th in FedExCup points -- Parker said his client is a good fit for what MLB.com was seeking.

"People ask me, 'Why Shawn?' I say, 'Why not Shawn?' " Parker said. "He's trying to build his brand and they wanted a young guy who they can grow with."

Although Stefani still throws the baseball around on occasion, most of his interest is now as a fan. He grew up as an Astros fan but knows it's tough to be one right now, as the Astros have the worst record in the American League and are 16 games behind the Texas Rangers in the AL West.

"It's exciting to watch the Rangers this year. And I like Boston and still pull for them," Stefani said. "But I like to pull for the Rangers too. Being a Texas boy, you've got to pull for the teams in Texas."

IRVING, Texas — Keegan Bradley's course record 10-under 60 at the HP Byron Nelson Championship was impressive for a number of reasons. Bradley managed to post the score with back-to-back bogeys on his card, and went 7 under over his last eight holes.

Another interesting tidbit about the round? Bradley had two Cleveland 4-irons in the bag during his record-setting round. You read that right: two 4-irons. We've seen players employ two drivers in the past (Phil Mickelson at the 2006 Masters comes to mind), but rarely do you see a pro carry two of the same iron.

Even though the numbers are the same, Bradley said the irons are slightly different when it comes to yardage and ball flight. The first 4-iron, a Cleveland 588 MT, has 21 degrees of loft and is a game-improvement long-iron that features a hollow head design that allows weight to be distributed for a lower, deeper center of gravity.

Even though the MT irons are sold as a set, a number of Cleveland staffers have been replacing their long irons and hybrids with the MT this season — including Bradley, who used a 3-iron at the beginning of the season before switching to a 4-iron.

IRVING, Texas -- Traditional long irons have become obsolete in recent years with the introduction of easier-to-hit hybrids and utility irons. At the 2013 Masters, only two players in the field carried a traditional 2-iron -- one of them being third-place finisher Jason Day, who used a TaylorMade Tour Preferred MC 2-iron during the week. 

Even though the iron is course-dependent -- Day switches between a 14.5-degree TaylorMade RBZ Stage 2 fairway wood and the Tour Preferred MC 2-iron depending on the layout -- it's clear the Aussie has some old-school tendencies when it comes to his equipment. 

It seems fitting that Day, the HP Byron Nelson Championship winner in 2010, would turn back the clock at the tournament that honors legendary golfer Byron Nelson and put a TaylorMade RocketBladez Tour 1-iron in the bag. 

Looking for a particular setup for the British Open at Muirfield, Day and TaylorMade Tour reps discussed a number of potential ideas about a month ago, including taking out the Day's driver and putting in a 2-wood. 

When they couldn't get the right configuration with the shaft and ball flight, Day kicked around the idea of going with a 1-iron to achieve the ball flight he was looking for off the tee. 

TaylorMade never produced a 1-iron in the RocketBladez line, so reps decided to do the next best thing, bending a 2-iron to 16.5 degrees and making the shaft a 1/2-inch longer. Day also went with a UST Mamiya Recoil Proto (125-gram) graphite shaft instead the current True Temper Rifle Flighted 6.5 shafts in his irons.

Day tested the club on Tuesday and liked it enough to pull his 2-iron and put the new iron in play.

"I was out there today and hit a couple of -- it was downwind and it was a 10 to 20 mph wind out there -- and there was a couple that went 300 [yards] easy with the bounce and roll as well. I want to say today with the wind hit about four, maybe five drives total [during the Pro-Am]. Everything else was a 1-iron and I didn't pull out the 4-wood at all. The ball flight was very strong."

While TPC Four Seasons will never be confused with a links-style layout, Day said he felt the course was the perfect place to test out the club ahead of the British Open -- especially with wind gusts expected to be anywhere from 15-20 mph the rest of the week.

"What the experiment was, was we were going to try a 1-iron and try it out here because we know if we have a 1-iron here and it works well in the wind, we go overseas to the British this year with full confidence that it's doing to go the right distance and can come out low and hit different types of shots when I need to. I know that it's not the British Open course but the wind is very strong here."

Outside of this week's HP Byron Nelson Championship -- Day said he used the 1-iron off the tee on nine holes during Wednesday's Pro-Am -- it's unclear when he'll use it again. 

With the Memorial Tournament and U.S. Open coming up, he hinted it could get some additional work before the British Open in July. 

"I think that it would be a very good club [at Merion, site of the U.S. Open], but I don't know until I get there. I'm definitely going to use it this week and I'm not too sure what I'm going to do with it for Memorial, but I know I'm going to use it at the British."

The minimalist running shoe movement has produced some ultra-light golf shoes over the last few years, with a few models tipping the scales at just under 10 ounces.

While it's unclear if there's a limit to how light golf shoes will get going forward, PUMA Golf became the new leader in the ultra-light clubhouse with the introduction of its Faas Lite Mesh shoe.

Weighing in a 6.5 ounces, the spikeless, minimalist golf shoe was designed to be worn "from the street to the course in lightweight, maximum comfort and trend-setting style." The shoe features a zero heel-to-toe drop that gives golfers the feeling they're playing barefoot, thereby allowing for a more natural stride and posture during the swing.

Even though the shoe is spikeless, PUMA added SmartQuill traction technology to Faas List Mesh that provides "directional grip elements to enhance ground contact for improved stability and traction." The shoe also includes corrugated flex grooves for more natural movement, increased flexibility and ground contract throughout the swing.

Along with Faas Lite Mesh, PUMA Golf also released a lightweight (8.7 ounces), waterproof version called Faas Lite. The shoe features Microfiber leather with stormCELL for waterproof protection, and comes with the same SmartQuill traction technology and zero heel-to-toe drop as Faas Lite Mesh.

Faas Lite Mesh will be available in three colorways (Brilliant Blue/Limeade, Vibrant Orange/White and White/Black) and retails for $90. Faas Lite will also be available in three colorways (White/Vibrant Orange, White/Black/Brilliant Blue and Black/Castle Rock) and retails for $100.

IRVING, Texas — Despite having only posted posted only one sub-70 round in competition since he switched to TaylorMade's Ghost Spider S belly putter, Padraig Harrington said he has no plans to go back to a conventional-length model anytime soon.

Harrington changed putters at the Wells Fargo Championship and opened with an 8-over 80 in the first round and promptly missed the cut. He followed the rough week up with a T75 at THE PLAYERS.

"I had no three-putts last week," Harrington said. "In my own stats, I only missed two putts under 8 feet which would be an all-time record, so it's still in the bag. And that was on tough greens last week. I would be happy if I putted like that all the time."

Looking for a something that would improve his putting stats -- he's currently ranked 123rd (-.123) on the PGA TOUR in Strokes Gained-Putting and 131st in putts made from inside five feet -- Harrington decided to give the belly putter a try.

“The R&A and USGA support the rules of golf and (anchoring) is well within the rules,” Harrington said at the Wells Fargo Championship. “I think (anchoring) is bad for the game of golf. But if something’s going to help me for the next three and a half years, I’m going to use it."

Like most putters, Harrington said the belly model has taken some getting used to -- especially on tap-in putts.

"I nearly dropped [the putter] on the ball at one stage last week because I'm not used to handling the putter and things like that. You're still not quite sure when you go to tap in a putt even from 18 inches when you're leaning in you just go and do it normally or as a belly putter, the familiarity is an issue."
