Russell Knox ... Undeterred by his playoff loss at The Honda Classic, he tied for 25th at Copperhead last week. It was the seventh top 25 in his last 15 PGA TOUR starts. Currently 23rd in the FedExCup standings (ninth-highest among non-winners this season), the 28-year-old from Scotland ranks 14th in fairways hit, 15th in greens in regulation, first in proximity to the hole, 14th in adjusted scoring and first in par-3 scoring. He's getting his first competitive look at Bay Hill.
David Hearn ... Back on the PGA TOUR for a fourth consecutive season following a five-year hiatus since his rookie year of 2005, the Canuck has been turning heads on the Florida Swing. He shared sixth place at The Honda Classic (with bookend 67s) where he led the field in strokes gained-putting, and then turned in four rounds of par or better to post a T8 at the Valspar Championship where he co-led in fairways hit. In between, the 34-year-old logged a T24 in Puerto Rico (T3 in GIR). He's a forgotten victim of Jordan's Spieth playoff victory at the 2013 John Deere Classic. Hearn's putter abandoned him in overtime. It may have simply been a case of nerves as he ranked inside the top 20 in most major putting stats last year. Those splits are marginally off this season, but it's still the strength of his game.
Trevor Immelman ... Now nearly six years removed from his Masters title, the South African has picked off just four top 10s in the last five-plus seasons, only one going for a top five. That slump was perpetuated by an injured left wrist on which he had surgery in October of 2009. With his five-year exemption having expired last year, the 34-year-old is fully exempt this season via the Web.com Tour Finals. He won the inaugural event before missing the next three cuts. Despite the injury, he's making his 12th consecutive appearance at Bay Hill. His most recent of three top 15s occurred in 2012 (T11).
Tim Wilkinson ... A veteran of parts of four seasons on the PGA TOUR, the Aussie is finally making his debut at Bay Hill. His 2009 season was cut short when he needed surgery to repair a torn ligament in his right thumb. After rehabbing at home, he returned to the U.S. in a bit of ignominious if not ominous fashion. During his second round of the 2010 Sony Open in Hawaii, when he attempted to escape a ditch after missing the fairway, his ball caromed off a tree and struck his collarbone. He withdrew immediately. Food poisoning and an aggravated thumb injury would lead to two more withdrawals in subsequent months. The left-hander lost his card until regaining it via the Web.com Tour in 2013. Both of his top 45s this season are top 10s.
Matthew Fitzpatrick ... When he emerged with the title at the 2013 U.S. Amateur, he became just the second from England to win in the 113-year history of the tournament (Harold Hilton, 1911). Four weeks prior, he claimed the Silver Medal as low amateur at The Open Championship (T44). It's his only previous start on the PGA TOUR. Now 19 years of age, slotted second in the World Amateur Golf Ranking (after sitting No. 1 following the U.S. Amateur crown) and focusing solely on his amateur career -- he left Northwestern University in January after one semester -- the 19-year-old is exempt into the first three majors if he remains an amateur. In addition to this week's automatic exemption reserved for the U.S. Amateur champ, he's scheduled to compete in next month's RBC Heritage on the same perk.
