"Everything went smooth," manager Paul Molitor said. "I didn't really ask for too many details. But he looked fine in the field, and his at-bats looked like he wasn't protecting or holding back anything."
Santana, meanwhile, is on the DL retroactive to April 20 with a strained lower back. He threw a bullpen session without any issues on Sunday and is scheduled to throw a two-inning simulated game on Tuesday. Santana, Minnesota's Opening Day starter, was 0-1 with a 3.00 ERA and 18 strikeouts in 20 innings before sustaining the injury.
"It won't be particularly long, but we want to get him between 30 and 40 pitches," Molitor said. "If everything goes well, we'll get him back in there Saturday."
• Right-hander Kyle Gibson, on the DL retroactive to April 23 with a strained right shoulder, played catch on Monday as he continues to rehab his injury. There's still no target date for his return, but the Twins are encouraged by his progress. He could throw a bullpen session as soon as this week.
• Closer Glen Perkins, out since April 11 with a strained left shoulder, could play catch at some point later this week, Molitor said, but Perkins is recovering slowly and has yet to throw since being placed on the DL.
• Right-hander Alex Meyer, who is set to make his first career Major League start against the Astros on Tuesday, will not have any pitch-count restrictions. It will be Meyer's first start since April 20, with Triple-A Rochester, as he was called up as a long reliever, only to replace lefty Tommy Milone in the rotation. Meyer threw 29 pitches in a relief outing on Friday; Molitor said he's stretched out enough to start without any limitations.
