TAMPA, Fla. (AP) — Andy Pettitte is making more progress in his rehab program for a strained left groin.

The New York Yankees pitcher was "feeling good" after going through a series of running and agility drills Tuesday at the team's spring training complex. The left-hander had resumed jogging on Sunday.

Pettitte hurt the groin while throwing a pitch during a July 18 games against Tampa Bay. He made 90 throws on level ground during Tuesday's workout.

The 38-year old, also sidelined by a groin strain in 2001, hopes to rejoin the rotation before a projected return date in late August.

Pettitte is 11-2 with a 2.88 ERA in 18 starts this season.
