PHOENIX -- Trevor Cahill's last four starts have been in Sacramento, Calif.; Reno, Nev.; Tacoma, Wash.; and Albuquerque, N.M. -- all a part of life in the Pacific Coast League, where Cahill has been stationed since the middle of June.
Cahill, a former All-Star, hasn't played a Major League game in more than a month.
But he will look to start his second chance, and the D-backs' second half, on the right foot when he gets the ball against the Cubs on Friday night at Chase Field.
"I wasn't contributing as much as I could, so [I got] a chance to go down there and work out some kinks and hopefully come back up here and contribute," Cahill said.
"I felt more comfortable as it went on. We tried different things. I had some good ones. I had some bad ones."
After getting bombed in a start for Class A Advanced Visalia -- going two innings and giving up four runs -- Cahill was promoted to Reno, where he was inconsistent.
In his first three outings, he gave up two runs twice and three runs once. But then Cahill found a bit of a groove, stretching out and going six innings and 5 1/3 innings without surrendering a run. However, he went only four innings and gave up four runs on five hits in his last Minor League start.
"I think he's just been getting built up," manager Kirk Gibson said. "One game he threw the ball really good and got tired. He's up over 100 pitches, now. … His last start, he didn't have very good control."
Said Cahill: "The last game, I didn't feel all that comfortable. I threw a bullpen and I felt a lot better."
Cahill said he worked on throwing out of the stretch while he was in the Minors. While he was with the D-backs earlier this season, opponents' batting averages jumped from .193 with the bases empty to .390 when there were men on base.
"Out of the windup, I've been feeling pretty good. Just the stretch wasn't very consistent," he said. "I just went back to in-between where I started to go and where I used to be. Hopefully it works out."
