LAS VEGAS -- Athletics third baseman Max Muncy came off the injured list Monday after missing about six weeks with a fracture in his left hand.
The Athletics announced before their game against Milwaukee on Monday night that they had reinstated Muncy. They optioned infielder Darell Hernaiz to Triple-A Las Vegas.
Muncy was recovering from a fractured fifth metacarpal. He last played on April 25.
He went 1-for-5 with two RBIs and a run scored as the Athletics lost 15-14 in 12 innings.
Muncy is batting .239 with a .308 on-base percentage, two homers, nine RBIs and two steals in 27 games.
Hernaiz batted .237 with a .318 on-base percentage, one homer, seven RBI and three steals in 47 games.
