Ruiz has been on the disabled list since May 20 because of a strained right hamstring. But Ruiz said Tuesday afternoon he is feeling much better, and after traveling with the team to Milwaukee this week, he hopes to begin a rehab assignment next week with Double-A Reading or Triple-A Lehigh Valley.
If that happens, the catcher said he hopes to be back in the Phillies' lineup by the beginning of the team's next homestand, which begins June 17.
"So far, it's real good," Ruiz said. "Yesterday, I was running and I was real happy because I don't feel anything. Today was the first day that I could swing in the cage and off the tee with soft toss and taking [batting practice]. It was almost full and regular BP. It feels good. I feel real close."
Ruiz is hitting .235 (12-for-51) with two doubles and two RBIs in 16 games. Backup catcher Erik Kratz is hitting .238 (29-for-122) with three doubles, seven home runs and 17 RBIs in 38 games.
