Ruiz's strain--classified as grade two--is expected to keep him out of action for three to four weeks. The team had seemingly planned on him missing a few days and called up catcher Humberto Quintero Monday to back up Erik Kratz in Ruiz's absence.
This will be the second extended absence this year for Ruiz, 34. He missed 25 games at the start of the year due to suspension. In 16 games, he has hit .235/.286/.275, a far cry from his All Star campaign of 2012.
Cloyd will start Tuesday night's game against the Marlins, according to MLB.com. He made a spot start for the Phillies earlier this season, allowing two earned runs to the Diamondbacks in 6.1 innings on May 10. Thanks to an off day, Philadelphia has not needed a fifth starter since that date.
Cloyd, 26. has become a decent pitching prospect for the Phillies after posting a 2.77 minor league ERA in 2011 and a 2.26 minor league ERA in 2012, working primarily as a starter both seasons. However, he has not posted good numbers in seven Triple-A starts this season.
Cloyd will likely remain in the rotation when a fifth starter is needed so long as John Lannan remains on the disabled list. Lannan, out with a strained knee ligament, is expected to return around mid-June.
