Since the departure of All-Star closer Mason Miller, the A's bullpen has been lacking star power. They've been getting the job done, sure, but they are certainly missing a strong arm to join the backend of the arm barn.Luckily, this season, they’ve seen some solid production out of guys like Joel Kuhnel, Hogan Harris, and Scott Barlow. However, none of these guys particularly blow away opposing hitters. Having someone with a scary fastball and a nasty off-speed pitch or two, like Mason Miller, is exactly what the team needs. Luckily for the A’s, they might just have someone similar producing big numbers in Triple-A.Sep 27, 2025; West Sacramento, California, USA; Athletics pitcher Elvis Alvarado (61) throws a pitch against the Kansas City Royals during the fifth inning at Sutter Health Park.

That same 2025 season, he would make his MLB Debut with the A's and became an important piece of the A's bullpen. He posted a 3.19 ERA in 42.1 innings last season and posted an 8.38 ERA before being demoted to Triple-A this season.The 2026 season started extra early for Alvarado when he was a bullpen arm for Team Dominican Republic in this year's World Baseball Classic.

However, there were a few bright spots in his big league stint this year. The 6-foot 6-inch hurler sat at an average of 98.1 mph, which is actually in the 94th percentile of MLB pitchers. He also paired that with an elite 34.8% whiff rate. However, he struggled to get opposing hitters to chase and to record punchouts.

The Aviators, the A's affiliate, play in a hitter-friendly Pacific Coast League. Their home site is Las Vegas Ballpark, which is also notoriously hitter-friendly. This inflates the scores of all the games and also pitchers' ERAs. This has not stopped Alvarado from posting a strong 2.53 ERA in 10.2 innings with the squad.Right-hander Elvis Alvarado has been real solid for the #Athletics Triple-A affiliate, Las Vegas Aviators.In 10.2 innings with the Aviators:2.53 ERA8 hits3 earned runs1 hold2 savesThe flamethrower could be working himself back into a bullpen spot in the big leagues 👀— Dylan Quinn (@dylanq_2) May 29, 2026It's also worth noting that Alvarado is getting looks as the Triple-A closer, a role that could open at the big league level at some point this summer. In just a few appearances, they have clearly shown that they trust Alvarado to collect big outs for their team.How Elvis Alvarado Fits Into the Current A’s Bullpen MixAug 15, 2025; West Sacramento, California, USA; Athletics pitcher Elvis Alvarado (61) throws a pitch against the Los Angeles Angels during the eighth inning at Sutter Health Park. Mandatory Credit: Ed Szczepanski-Imagn Images | Ed Szczepanski-Imagn ImagesThe A’s bullpen has shockingly been solid in the 2026 season. However, the club has no true closer, and that could change if it stays near the top of the AL West standings. There is a current lack of left-handers in the A's bullpen, with just Hogan Harris and Jose Suarez as the lone two. The remaining arms are all righties like Alvarado, which could make it a little more difficult for him to secure a roster spot.Apr 22, 2026; Seattle, Washington, USA; Athletics manager Mark Kotsay (7) talks with staff in the dugout following a batted ball that was trapped in the jersey of Seattle Mariners starting pitcher Logan Gilbert (36, background) during the first inning at T-Mobile Park. The play was ruled a hit. Mandatory Credit: Joe Nicholson-Imagn Images | Joe Nicholson-Imagn ImagesHowever, the main spot where Alvarado could fit is as a late-inning reliever. Joel Kuhnel and Jack Perkins have been in that role for the last month or so, and with Perkins struggling, they could use the flamethrower in late innings.Perhaps the A's will give Alvarado a few more weeks in Triple-A to continue his dominance before ultimately joining the team's bullpen.Add us as a preferred source on GoogleFollow
