The Phillies selected catcher Humberto Quintero's contract from Triple-A Lehigh Valley. The club placed right-hander Mike Adams on the DL with a strained back to make room for Quintero. Right-hander Tyler Cloyd will take Ruiz's spot on the roster Tuesday and start against the Marlins.
Ruiz injured the hamstring running the bases in the second inning of Sunday's 3-2 victory over the Reds at Citizens Bank Park. He had hit .235 (12-for-51) with two doubles and two RBIs in 16 games after missing the first 25 games for using a banned stimulant. He hit .325 (10-for-31) in his previous 10 games.
Phillies catchers have a .582 on-base-plus-slugging percentage this season, which ranks 27th in the Majors. They were counting on Ruiz to boost that position, but he lasted less than a month.
"We were comfortable with the [catching] situation we had to start the season," Phillies assistant general manager Scott Proefrock said. "Q did a good job for us. I think we're comfortable with what we have. We're not going to stop looking, but I don't think we're actively out there pursuing anything. But you keep your eyes and ears open."
