HOUSTON -- Max Kepler and Blake Parker both did not play during the Twins' series in Baltimore due to illness, but Kepler went 1-for-3 out of his customary leadoff spot to extend his on-base streak to 14 games in Minnesota's 9-5 victory over the Astros on Monday night, and Parker pitched a scoreless ninth inning.

Both Kepler and Parker were available on Sunday, but manager Rocco Baldelli elected to give them an extra day of rest to recover more fully.

"I can't tell you exactly what their stomachs feel like at the moment, but I can tell you they're good to play," Baldelli said before the game.

Moya moves to Triple-A in rehab assignment
Left-hander Gabriel Moya was moved to Triple-A Rochester on Monday in a continuation of his rehab assignment as he recovers from left shoulder tendinitis that sidelined him during Spring Training. Moya had first been sent to Double-A Pensacola on Friday to begin his rehab assignment.

Moya appeared in two games for Pensacola, striking out four in 1 2/3 scoreless innings, though he allowed three hits and walked a pair. Baldelli suggested that Moya's return to the team is not imminent, as the team remains cautious with arm ailments and hopes to see how Moya will respond to the variety of situations that Twins relievers have experienced this season.

"A lot of our guys out of the bullpen, as we've seen, we're going to ask guys to go back to back, we're going to ask guys to go 2 1/3 [innings]," Baldelli said. "We're going to ask guys to do different things, especially with the fact that we've been playing a position player up for a while and a bullpen spot down."

No word on Wednesday's starter
After Friday night's rainout and Saturday's doubleheader in Baltimore pushed up Jose Berrios' schedule, the Twins still haven't determined who will start Wednesday's series finale in Houston. Baldelli said the Twins will evaluate how their pitching staff is used early this series before making a decision.

Zack Littell, currently at Triple-A, could pitch on regular rest Wednesday. Among in-house options, Adalberto Mejía has worked out of the Twins' bullpen at the start of the season but was stretched out as a starter in Spring Training and hasn't pitched since last Wednesday.

"We're not going to be able to make a call or even imply who we might think who might be the person, because there are several people that probably could make that appearance for us," Baldelli said. "That's if we even go with a typical starter who we're going to ask to just pitch. We could do some other things as well."
