Alvarez has just three hits in 16 at-bats, but more importantly, he has not had any recurring issues with his right quad. The Pirates have not indicated when Alvarez will be ready to come off the disabled list, though it likely will not be until after the All-Star break.
Alvarez will now move on to Triple-A Indianapolis, where he will continue his rehab work.
Other injury updates:
Ronny Cedeno (concussion) has still not been cleared to resume exercising, though the shortstop said on Monday that he is feeling better now than he was this weekend. In addition to recovering from the concussion, Cedeno is also now fighting off congestion from a cold.
Jose Tabata (left quad strain) estimated that he is back at 80-percent health, but that he wants to be cautious in his return to the field.
"I don't feel ready, yet," Tabata said. "I think it's more mentality, because I don't want to get hurt again."
He did some light running on Monday, and took some swings in the cage. Tabata is expected to go out on a Minor League rehab assignment before rejoining the team after the All-Star break.
Joe Beimel (left elbow inflammation) made his first rehab appearance with Bradenton on Friday, and pitched one scoreless inning and struck out two. He will move on to Double-A Altoona for the next phase of his rehab assignment. If Beimel doesn't rejoin the team this week, he'll likely do so in Houston immediately after the midseason break.
Chris Snyder (back surgery) began workouts last week and said he is feeling great.
"I'm on the road [to recovery]," Snyder added.
