PHOENIX -- The D-backs' already-depleted rotation took another hit when starter Trevor Cahill was forced to leave Wednesday's 3-1 win over the Marlins in the second inning with a bruised right hip.
Cahill said following the game that he expected to be able to make his next start, which would be next Tuesday against the Nationals in Washington.
Cahill was hit on the right hip by a line drive off the bat of Marcell Ozuna in the top of the first inning. The ball deflected to third baseman Martin Prado, who threw Ozuna out to retire the side.
Cahill came out to warm up for the second inning and before he threw a pitch to leadoff hitter Derek Dietrich, Arizona pitching coach Charles Nagy visited the mound with one of the team's trainers.
Cahill was left in the game, but after falling behind Dietrich 2-1, Nagy and the trainer came out once again and this time they removed Cahill and brought in right-hander Josh Collmenter.
"I thought I could get through it," Cahill said, "and they just didn't want to risk anything. It was sore, my stride was a lot shorter, but I felt like I could have made an adjustment and pitched through it."
The D-backs already have Brandon McCarthy on the disabled list and are without the services of Ian Kennedy for 10 games due to a suspension, so they did not want to take any chances with Cahill.
"He said he could power through it," manager Kirk Gibson said. "But just watching him warm up it didn't seem like he was pushing off very good and we were worried about him hurting his arm."
Josh Collmenter saved the bullpen by throwing six scoreless innings of relief of Cahill, the second-longest relief stint in franchise history.
Heating up at plate, Montero doesn't want day off
PHOENIX -- After struggling to find his hitting stroke during the first two months of the season, catcher Miguel Montero has been swinging the bat well and he doesn't want any time off to get in the way.
"Obviously I'm starting to feel better at the plate, and I really have to take advantage of that," Montero said. "I never want a day off, period, but now I'm really asking him not to give me one, because I feel better at the plate and I just want to continue that. If I get a day off, I might go backwards a little bit."
Manager Kirk Gibson granted Montero's request and started him in Wednesday's afternoon game following Tuesday's night game.
With the D-backs having Thursday off as well as next Monday, Montero will get his rest then.
After bottoming out with a .180 batting average on May 19, Montero has managed to raise his average to .225.
In his last 40 plate appearances, he's hitting .361 with a .400 on-base percentage.
"I'm feeling better and better and better -- and hopefully it stays there," Montero said.
Gibson not ready to name starter for Sunday's game
PHOENIX -- The D-backs have not announced a starter for Sunday's series finale with the Reds, but Randall Delgado would seem to be the natural choice given his performance Tuesday night.
Delgado allowed two runs on eight hits over seven innings against the Marlins.
"We haven't talked about it," manager Kirk Gibson said when asked who would start Sunday. "It's possible he could start again, but it hasn't been determined. A lot depends on how we get through the weekend."
Delgado had battled for the No. 5 spot in Spring Training, but he struggled with his command and lost out to Patrick Corbin.
When the D-backs needed a bullpen arm earlier this month, Delgado was called up from Triple-A Reno, and he made one appearance before being sent back down.
Delgado showed excellent control Tuesday by not issuing a walk and while he has made some mechanical adjustments since the spring, that was not the main reason for his improvement.
"I tried everything, but I think it was more mental," Delgado said. "When you get confidence, you feel better. It's not so much about mechanics, it's more about being confident."
Feeling better, Chavez could start rehab stint soon
PHOENIX -- Third baseman Eric Chavez has recovered at a faster than expected pace from a strained right oblique injury and could begin a rehab stint as soon as next week.
"Everything has been good -- hitting, running, throwing," Chavez said. "I didn't know really what to expect, but [it's] gone really good."
Chavez suffered the injury May 30 while taking a swing against the Rangers in Texas.
At the time of the injury, Chavez was one of the team's best hitters with a .325 batting average to go with seven homers and 25 RBIs.
Chavez does not think it will take him long to get his timing back at the plate.
"I told [manager Kirk Gibson] as far as timing is concerned, I don't need much," Chavez said. "For me, it will be more how does a check swing feel, how does a swing and miss feel, how does a 2-0 swing feel, all that stuff more than my timing. It doesn't take me long. I've only been out three weeks or whatever, so it's not going to take long."
