The Indians saw what they needed to see Saturday from Justin Masterson in his bullpen session. Masterson's next stop will be the mound at Dodger Stadium for Tuesday night's game against Josh Beckett.

"He's all set for Tuesday," said manager Terry Francona.

Pitching coach Mickey Callaway watched Masterson throw Saturday morning and came away impressed.

"He felt good and let the ball go," said Callaway. "His command was good and his velo was good. The action on his pitches was good."

Masterson was scheduled to start Sunday against the Mariners and Felix Hernandez, but after struggling against Arizona on Tuesday, the Indians revealed that Masterson has been pitching with a sore right knee since early April.

They shut him down for two days, during which he rehabbed the knee and took anti-inflammatory medication.

"The benefit of having those two days is that you know you have two days that you can spend just crushing the knee as far as therapy, movement, icing and stimulation," said Masterson. "It seems like two days is a short amount of time, but it really gives you an opportunity to do a lot of things with the knee."

Masterson said he did not get an injection in the knee.
