By Fred Albers, PGATOUR.COM Correspondent SILVIS, Ill.-- You can never discount the importance of a putt. Troy Matteson was first in the John Deere Classic in Strokes Gained-Putting. Zach Johnson was second in SGP. Both players made recent changes in their strokes. Johnson has moved his hands a little further forward, giving the ball a truer roll. Matteson was also disappointed with the way the ball was leaving the face of the putter. He concentrated on taking his hands out of the stroke and making more of a pendulum movement. Matteson says he wants to keep the triangle together. That means the area formed by the shoulder blades and forearms stays connected during the stroke. It paid off with a 60-foot eagle putt on the 71st hole which tied him for the lead at TPC Deere Run on Sunday. Stricker strokes:  Steve Stricker had his worst putting round of the tournament on Sunday. He took 30 strokes and was ranked 54th for the week in Strokes Gained Putting. Perhaps most damaging were a pair of misses from 5 feet. Stricker missed a 5-footer for par at the 10th hole and misfired on a 5-footer for bogey on the 14th. Approach shot:  Never give Johnson a second chance. He doubled the first playoff hole and then drove into the fairway bunker when playing the 18th again. This time the lie was much better and so was the shot. From 193 yards out, Johnson hit it to within a foot to win the tournament. It's a shot that will rival Bubba Watson's playoff approach at the Masters for shot of the year. Zach's experience was evident as he is now 3-0 in playoffs. Ball supply:  If you would like a golf ball, just follow Brian Harman around the course. He routinely gives balls away. He is not superstitious, either. Harman gives away balls after making birdies or bogeys. He goes though about a half dozen balls a round, spotting a child and handing out a souvenir. Timed out:  John Senden says he's on to something. He is taking less time on the greens, taking less time to read putts and letting his natural athletic ability help him. Senden entered the week ranked 137th in Strokes Gained-Putting and this week ranked 25th. He's always been a great ball striker, ranking fifth on TOUR in greens in regulation. With the help of better putting, Senden finished fourth this week.
