Dan Meyer, a former top A's pitching prospect, will be joining the Midland roster on a rehab assignment. Reliever Jeff Coleman has left the Midland team and has announced his retirement. The Rockhounds will be filling their final spot with a pitcher, likely Luis Ramirez from Stockton.
Putnam missed nearly three months of the 2006 season with a knee injury, but he returned to the field in August and had a big month, hitting eight homers in the season's final month. He used the momentum of that final month to get off to a fast start this season. During the spring, Putnam was red-hot, collecting three hits in four at-bats in major league camp and playing well during the A's-Giants Bay Bridge Series.
In 2005, Putnam was the only A's minor leaguer to drive-in at least 100 runs, which he did for the Stockton Ports. He hit .307 that season with 15 homers. Putnam starred in college for Stanford University, where he hit 16 homers in both the 2003 and 2004 seasons.
Putnam and Braden will join Travis Buck and Jay Marshall as rookies on the A's roster, which has gotten increasingly younger in the recent weeks.
