Ken Korach was back on the air for the A’s for the first time this season on Monday.OAKLAND — Ken Korach was back at the O.co Coliseum on Monday and back on the air.

The A’s lead radio announcer, in his 20th season with the team, has missed the first 46 games while recovering from an injury to his artificial left knee.

Korach was expected to meet with the A’s medical team to evaluate his progress. He was back in the broadcast booth and took over the play-by-play duties for the third inning.

Korach’s return is not on a full-time basis yet, but he will call the occasional game while he continues to return to full health.
