James Simmons: Simmons may be only two months removed from college, but he is pitching like a veteran for the Midland Rockhounds. The A’s top pick in this year’s draft has been working out of the bullpen for the Rockhounds and he has been nearly unhittable. In 12.2 innings, Simmons has allowed six hits and two walks. He has 11 strikeouts and has allowed only one run. According to A’s Director of Player Development Keith Lieppman, Simmons will stay in the one-to-two innings per appearance range for the rest of this season in order to limit his total innings for the season. Simmons threw 123.2 innings for UC-Riverside this year.
Dan Meyer: After a rough June, Meyer has been red-hot in July. The left-hander has a 2.05 ERA in five starts. In his last three starts, Meyer has allowed only nine hits and two runs in 19.2 innings. On July 20, Meyer struck out 11, matching a season-high. On the season, Meyer has 81 strikeouts in 94.2 innings.
Trevor Cahill: The A’s top pick in the 2006 draft has been light’s-out during his last three starts. He has allowed only three runs, 10 hits and five walks in 19 innings.

On the season, Cahill has a 3.80 ERA in 68.2 innings and he has struck out 73.
