In a move reported by ESPN’s Jeff Passan, the Oakland Athletics have traded right-handed pitcher Lucas Erceg to the Kansas City Royals. The details of the return package have not been made public yet, but given Erceg’s potential and long-term team control, the Athletics could be expecting a significant return.
Erceg’s path to the majors has been anything but typical. Originally drafted as an infielder, he made a dramatic career shift by converting into a pitcher, where he’s since emerged as a powerful bullpen arm. Oakland acquired Erceg from the Milwaukee Brewers in 2023 in a low-risk cash deal. Since then, he has evolved into a key contributor in the A’s bullpen.
So far in the 2025 season, Erceg has compiled a 2-3 record with a 3.68 ERA and a 1.20 WHIP. He’s been primarily deployed in high-leverage situations, often pitching the eighth inning ahead of All-Star closer Mason Miller. His high-velocity fastball and late-inning effectiveness have made him a valuable setup man.
Erceg is under team control through the 2029 season, which adds considerable value to his profile. For the Royals, acquiring a hard-throwing, cost-controlled reliever helps bolster their bullpen depth as they aim to stay competitive in the American League.
More information on the players or prospects heading to Oakland in return will likely emerge soon, but for now, the Royals have secured a bullpen arm with upside, while the A’s continue to build for the future.
