A’s right-hander Joey Estes has undergone surgery to address a herniated disc in his lower back, according to the MLB.com injury tracker. That obviously ends his season a month after he landed on the 15-day injured list. Estes had just been recalled from Triple-A Las Vegas a few days before suffering the injury. He tossed four scoreless innings out of the bullpen against the Mariners on August 24.
That’ll go down as Estes’ only MLB appearance since April. The 23-year-old opened the season in Mark Kotsay’s rotation. Estes was tagged for six runs in each of his first two starts and immediately lost his active roster spot. The A’s optioned him and he spent the majority of the season in Vegas. Estes took the ball 17 times in the Pacific Coast League. He surrendered 5.51 earned runs per nine across 80 innings in that difficult setting.
A 16th-round pick by the Braves in 2019, Estes signed for an overslot $500K out of high school. Atlanta traded him to the A’s as arguably the fourth piece of the Matt Olson return shortly after the ’22 lockout. Shea Langeliers is the only player from that group who has panned out. Cristian Pache and Ryan Cusick have been cut loose.
Estes has occupied a 40-man roster spot since being called up at the tail end of 2023. He took the ball 25 times and logged 127 2/3 innings last year, but he posted an ERA above 5.00 with a modest 17% strikeout rate. Estes still has one minor league option year remaining. He’s not a lock to hold his 40-man spot throughout the winter. If he does, the A’s could send him back to Las Vegas as rotation depth.
Jacob Lopez has a much better chance of securing an Opening Day rotation spot. The 27-year-old southpaw has had a solid first season in Sacramento. The A’s acquired Lopez as part of the offseason deal that sent hard-throwing righty Joe Boyle to Tampa Bay. Lopez has fanned 28.3% of batters faced through 92 2/3 innings. While his 4.08 earned run average doesn’t jump off the page, he carried a 3.28 mark into his most recent start on August 24. Lopez was blasted for nine runs in two innings that day and landed on the injured list with a flexor strain thereafter. It’s fair to conclude he wasn’t pitching at anything close to full strength.
Unlike Estes, Lopez may be able to get back on the mound before the end of the season. The injury tracker notes that the rookie lefty threw a bullpen session yesterday while traveling with the team to Boston. The A’s are keeping open the possibility that Lopez makes an appearance during their final series against the Royals next weekend. That’d probably be a relief outing or very abbreviated start but would allow Lopez to enter the offseason with some positive momentum rather than finishing the year with a season-ending forearm injury.
The A’s are playing out their fourth consecutive losing season (barring a 9-0 finish to get to .500). Yet for the second straight year, they’ve had an encouraging second half. The A’s have had a winning record in each of the past three months. They’re 31-24 with a +66 run differential since the All-Star Break. Most of the credit goes to a talented offensive core. That’s not the entire explanation, as the A’s have quietly gotten excellent work out of a patchwork bullpen despite trading Mason Miller.
Since the deadline, the A’s have an MLB-best 2.81 earned run average from their relief group. They’re middle of the pack in strikeouts, walk rate, and whiffs. They’ve certainly benefited from an MLB-low .247 average on balls in play, but it’s still impressive production from an inexperienced group. Only Sean Newcomb, a journeyman brought in from Boston in a late May DFA trade, has even two years of service time among A’s relievers.
As MLB.com’s Theo DeRosa wrote this week, the A’s have found that success without many set roles. They haven’t had a designated closer since the Miller trade. Hogan Harris has picked up his first four career saves to lead the team over that stretch. He’s one of five relievers — Newcomb, Michael Kelly, Tyler Ferguson and Osvaldo Bido being the others — to record at least one save. (Bido’s was of the three-inning variety in a blowout victory.)
Harris, a pure reliever this season for the first time in his career, has become Kotsay’s most trusted leverage arm. He carries a 3.30 ERA with a solid 23.3% strikeout rate across 60 innings. Harris’ command comes and goes, but he looks like a solid bullpen piece whom the A’s have under club control for another five seasons.
Meanwhile, Newcomb has turned back the clock with his best season since at least 2019. The former first-round pick owns a 1.75 ERA while striking out a quarter of opponents over 51 1/3 innings since the A’s reacquired him. His 7% walk rate is the best of his career, and he has been lights out (0.96 ERA in 28 frames) in the second half. Newcomb will be a free agent and has certainly pitched his way to a major league deal after settling for a non-roster contract with the Red Sox last winter.
never trade with the rays .. always trade with the A’s
Coincidentally, the A’s have gotten better results out of the Lopez for Boyle swap with Tampa.
The Rays haven’t been winning a large margin of trades recently. A lot of brains were taken out of that FO.
The Paredes deal looks like a total L.
I see Nuke is doing good in a relief role again. Always wanted to start but better in the bullpen.
A’s should absolutely resign Nuke. He’s been lights out as a reliever…
I’m guessing if the A’s non-tender Estes he probably won’t be joining the Mariners any time soon…
Omg an A’s article. Good job team
It still does not make any sense that Mark Kotsay has a job. Had the A’s not scuttled in May and June – they would be in the playoff picture. 7 wins in May and a stretch at one point of losing 19 of 23. Has any other MLB ever survived a stretch where they had multiple 9+ game losing streaks in less than a month?
Zero expectations this season, so yeah, keep the kids playing and don’t look at the W/L column.
Incorrect. The expectation was the A’s were going to be a .500 team with an outside chance at the playoffs.
Let’s be real. They have a lot of good, young players yes but this ain’t a playoff team. They would get cooked in a 5-game series.
Next year they’ll be scary tho especially with LDV and some of those arms coming up like Arnold, Lin, and Jump. Having Muncy and Lopez healthy will be a big boost as well.
