ST. PETERSBURG, Fla. -- Yankees manager Joe Girardi did well in keeping it a secret as long as he could.



Girardi said he had surgery to repair torn meniscus in his right knee May 10.



He was walking around the Yankees' clubhouse with the knee heavily wrapped in ice after a 3-2 win over the Rays at Tropicana Field.



"I did a good job keeping it quiet, right?" Girardi said, smiling.

He didn't appear to be limping.

The procedure didn't stop him from attending any games. He missed Thursday's game against the Rays here, but he said that was because he was attending his daughter's high school graduation.



It's unclear what caused the injury. Girardi played 15 seasons in the majors, catching 1,247 games, good for 10,061 1/3 innings.



It didn't seem to affect him when he went all out following his ejection from Saturday's loss against the Rays, walking to the plate and covering it in dirt.

A few other Yankees injury updates:

Yankees right fielder Aaron Judge said he was fine after his incredible diving catch in right field on Sunday.

First baseman Greg Bird (right ankle bone bruise) may start hitting soon, Girardi said. Bird has been on the disabled list since May 2. He's been doing light running.

Closer Aroldis Chapman (left shoulder inflammation) may start throwing soon, Girardi said. He's been on the DL since May 14. The Yankees said Chapman wasn't going to throw for 10 days after they put him on the DL.
