Manager Kirk Gibson announced the D-backs starting rotation following the All-Star break will be RHP Trevor Cahill, LHP Wade Miley, RHP Josh Collmenter, LHP Vidal Nuno and RHP Chase Anderson. Cahill, 26, started 6 games for the Aces and went 2-2 with a 3.49 ERA (11 ER in 28.1 IP) as opponents hit .214 (21-for-98) with 20 walks and 27 strikeouts. He held righties to a .164 average (9-for-55) with 12 walks and 19 strikeouts while lefties hit .279 (12-for-43) with 8 walks and 8 strikeouts.
In 19 games (4 starts) for the D-backs this season, Cahill is 1-6 with 1 save and a 5.66 ERA (26 ER in 41.1 IP). In his 4 starts, he is 0-4 with a 9.17 ERA (18 ER in 17.2 IP). He was designated for assignment on June 9 then optioned to Reno on June 12. Bolsinger, 26, has gone 1-6 with a 5.50 ERA (32 ER in 52.1 IP) in 10 games (9 starts) over 2 stints with the D-backs. In 9 starts for the Aces this season, he is 5-1 with a 2.73 ERA (16 ER in 52.2 IP).
Cahill's control, which was the main issue that got him first taken out of the rotation, then sent down to the minors, has remained a bit wobbly, with those 20 walks in only 30.1 innings of work. He pitches for the Aces on Saturday, and walked five in four innings of work, so I'm a little surprised to see him returning to the majors, since it doesn't appear that he has obviously been "fixed." It appears the "definite timetable" talked about by Kevin Towers for the return of Cahill was the All-Star break. That limited duration may have been why Cahill agreed to the minor-league assignment to begin with.
We wave goodbye to Mike Bolsinger for now - like Brandon McCarthy, another D-back pitcher whose peripherals didn't match up to his actual performance. The pitching rotation after the All-Star break was also announced: Cahill will start the first game on Friday, with Wade Miley and Josh Collmenter following in the series against the Cubs, then Vidal Nuno and Chase Anderson take the first two games versus the Tigers.
