Carlos Ruiz suffered a Grade 2 hamstring strain on Sunday. He will be placed on the DL on Tuesday, to make room on the roster for Tyler Cloyd. Cloyd has to be activated to make his second start of the season.

Ruiz is expected to be out for 3-4 weeks, a big blow to an offense that relied heavily on the All-Star catcher last season.

And than there is Ryan Howard, who is out of the starting lineup for the second straight game with a sore left knee. Howard's status is the most interesting only because it's a little up in the air.

Howard, who is in the second year of a five-year, $125 million contract, had an MRI on Monday morning in Philly that revealed inflammation in his left knee. It's the same leg that cost Howard half of last season: he had surgery on his left Achilles in October of 2011.

Howard had a cortisone shot on Sunday.

"He’s got some changes in his meniscus and his knee," head Phillies athletic trainer Scott Sheridan said of the MRI results. "And he’s also got some inflammation in the knee that concerns us."

Howard is currently listed as day-to-day.
