O'Loughlin

The 24-year-old Australian southpaw broke through to the big leagues and appeared in four games for the Athletics during the 2024 season, registering a 4.66 ERA, 1.86 WHIP and a 6/5 K/BB across his 9 2/3 innings of work. If you’re trying to fight for a spot in a big league bullpen, latching on with the Rockies makes a ton of sense as there are plenty of opportunities available. Expect to see O’Loughlin at Coors Field at some point in 2025.

O’Loughlin was designated for assignment earlier this week. He passed through waivers unclaimed and has the option to elect free agency. Even if he does accept his outright assignment, he can become a minor league free agent at the end of the season. O’Loughlin had a 4.66 ERA, 1.86 WHIP and six strikeouts in 9 2/3 innings for the Athletics this year.

O’Loughlin, 24, made four appearances for the A’s in the first half of the season, allowing five runs in 9 2/3 innings. He has a 6.19 ERA in 10 starts and 18 relief appearances for Triple-A Las Vegas.

O’Loughlin, 24, will head back to Vegas with the Athletics reinstated Kyle Muller (shoulder) off the injured list. O’loughlin will likely be back in a middle-inning role before the summer comes to a close.

O’Loughlin provides Oakland’s bullpen with a fresh arm ahead of Tuesday’s game against the Angels. The 24-year-old lefty has hurled seven scoreless innings over three relief appearances this season in the big leagues.

O’Loughlin was sent down to make room for Michel Otañez, with Otañez up from Las Vegas in the corresponding transaction. O’Loughlin will likely be back as a helper in middle relief at some point this summer.

O’Loughlin will bolster Oakland’s bullpen after receiving his first call-up. The 24-year-old southpaw has compiled a pedestrian 5.12 ERA, 1.60 WHIP and 44/16 K/BB ratio across 38 2/3 innings (10 appearances, eight starts) this season for Triple-A Las Vegas. He figures to operate in middle relief situations.

The 24-year-old lefty receives his first call-up the majors after posting a serviceable 5.12 ERA, 1.60 WHIP and 44/16 K/BB ratio across 38 2/3 innings (10 appearances, eight starts) for Triple-A Las Vegas.

It’s a large batch of cuts, and there’s definitely some talent mixed in there, but no one who was truly expected to crack the team’s Opening Day roster. Jordan Diaz saw significant time with the A’s during the 2023 season and he’ll surely get another chance at some point in 2024. Estes is somewhat surprising, as he was absolutely dealing in Cactus League play — posting a 1.29 ERA, 0.43 WHIP and an 8/1 K/BB ratio across seven innings in his three outings.

According to the agent for the 23-year-old southpaw, he had up to 15 minor league offers on the table before ultimately signing with the Athletics. O’Loughlin spent his first five minor league seasons in the Tigers’ organization, most recently registering a 3.99 ERA, 1.46 WHIP and a 118/52 K/BB ratio across 124 innings between High-A West Michigan and Triple-A Toledo. The Australian native will add rotation depth for the A’s and could make his big league debut at some point during the 2024 campaign.
