The Web.com tour goes by nicknames like the Go-Low Tour and the Bombers' Tour: It's aggressive golf played by the guys who are just a lob shot away from earning a PGA Tour card. And it's about to get more competitive. The top-25 players on the Web.com money list at the conclusion of the Cox Classic on Aug. 25 will earn PGA Tour cards for next season. Michael Putnam was the leader at the end of June with $386,634. The top 25 will be joined by another 25 players who earn their way onto the big tour through a new four-tournament playoff culminating with the Web.com Tour Championship Sept. 26-29 on Dye's Valley Course in Ponte Vedra Beach, Fla. This playoff takes the place of the tour's annual qualifying tournament, which will now be used as a gateway to playing on the Web.com Tour. The Web.com playoffs can be seen on Golf Channel. Here are four players to watch.
