Bielak heads to Arizona as extra organizational relief depth after compiling a respectable 4.63 ERA, 1.54 WHIP and 160/91 K/BB ratio across 204 innings (76 appearances, 21 starts) from 2020-2024 between the Astros and Athletics.

Bielak gets the boot from the roster to make room for Joe Boyle. The 28-year-old will hit the waiver wire, but it’s unlikely a team will put a claim in on the right-hander this late in the year.

Bielak will add bullpen depth for the A’s for the final three weeks. The Athletics optioned Brady Brasso to make room for Bielak on the roster.

It’s a tad surprising there wasn’t a suitor out there for Bielak, who has been a durable innings-eater at the major-league level the last few seasons. The 28-year-old righty will presumably stick around with Oakland as extra organizational depth.
