This week’s edition of What’s in the Winners’ Bags is up, and you can see it here http://www.pga.com/golf-equipment/winners-bag/whats-in-winners-golf-bags-week-july-15-2012 
A few quick observations:
1. After winning the Senior PGA Championship with a Scotty Cameron Studio Select Laguna 1.5 putter seven weeks ago, Roger Chapman took it out of his bag and replaced it with a Rife Aruba and then won the U.S. Senior Open. Both putters are Anser-style blades that look and feel fairly similar to each other. Just goes to show that even after by far the biggest victory of his career, Chapman – like all the rest of us – is never fully satisfied with his gear.
2. Johnson proved more loyal to his flatstick, winning both his 2012 titles with an FGP Black model from SeeMore. It’s fairly rare when one of the smaller companies wins a big tournament, so a week in which underdog puttermakers capture both of the two biggest events on U.S. soil is well worth noting.
3. Zach Johnson (John Deere Classic) and Roger Chapman (U.S. Senior Open) both won on Sunday, and both also won on May 27 (Johnson at Colonial and Chapman at the Senior PGA Championship). So each has two wins on the year, and both came on the same days.
