Oakland Athletics reliever Lucas Erceg (forearm) is going to be placed on the injured list with forearm tightness, according to manager Mark Kotsay. The official transaction has not occurred yet but Erceg was already sent back to Oakland for additional testing. The exact severity of the injury should be known in a couple days. It is a tough blow for the Athletics bullpen as Erceg has pitched great as a setup man in 2024. The 29-year-old posted a 2.86 ERA, 1.00 WHIP, two saves, eight holds and 27:8 K:BB across his first 22 innings this season. Austin Adams is the likely candidate to take over Erceg's duties in front of Mason Miller.
