TAMPA, Fla. — New York Yankees left-hander CC Sabathia tested his injured right knee Saturday, allowing two runs and three hits in 21/3  innings in his first rehabilitation game since going on the disabled list in May.

Sabathia walked one and struck out two for Class A Tampa against Dunedin in a Florida State League game. He threw 37 pitches.

“I felt really good,” said Sabathia, who expects to make at least one more minor-league start.
