• Outfielder Darin Mastroianni, on the 60-day disabled list with a left ankle stress reaction, is now working out in Fort Myers, Fla., with the Twins' Gulf Coast League affiliate. Mastroianni hasn't begun a Minor League rehab assignment yet, however. Antony said the outfielder is just working out and getting prepared to get back into game situations.

• Oswaldo Arcia was back in the Twins' lineup on Monday, batting sixth and playing left field. Gardenhire said Arcia (right hand bruise, knee soreness) could have played on Sunday "if we really needed him to."

"He was fine, though," Gardenhire added. "His knee was a little sore from that funny play at home plate at home the other day. Good day. He had a little bit of a break, then get him back out there."

Arcia went 1-for-4 in Monday's 7-4 loss, and was thrown out trying to stretch his single to a double in the fourth.

• Right-hander Nick Blackburn, working his way back from right wrist surgery, threw five innings for the GCL Twins on Monday. Blackburn gave up two runs on six hits and struck out five.

"Felt good, so that's all positive," Antony said about Blackburn.

• Antony said Alex Meyer, the Twins' No. 3 prospect according to MLB.com, is scheduled to begin an interval throwing program on July 16, which would put him back in games in early August.

• Right-hander Cole De Vries was placed on the seven-day disabled list at Triple-A Rochester with a right elbow strain.
