A’s Promote Anderson To Double-A

The Athletics promoted lefthander Brett Anderson from high Class A Stockton to Double-A Midland, forming one of the more prospect-laden rotations in the minors.

Anderson had a 4.14 ERA in the high-offensive environment of the California League, with most of the damage centering around three starts in May when Anderson was battling through a thumb injury, which may have hampered his command. His overall numbers remained strong, however, as Anderson used his fastball-curveball-changeup combination to strike out 80 while issuing just 18 walks in 74 innings.

Anderson joins righthanders Trevor Cahill and James Simmons in the Midland rotation. Cahill, 20, made his first start for Midland on Friday after establishing himself as one of the most dominant pitchers in the minors with Stockton.

Simmons, Oakland’s first-round draft pick in 2007, was dominant in his first seven starts for Midland. Simmons had a 2.02 ERA in 35 2/3 innings during that stretch with a 31-8 K-BB mark. However, Simmons had a rough start against Frisco on May 14, then went on the disabled list. Including that May 14 start, Simmons has a 9.35 ERA in his last five starts, with 16 strikeouts and five walks in 17 1/3 innings. On the season, he’s 2-4, 4.08 with 47 strikeouts and 14 walks in 53 innings.
