Oakland A claims Domingo Tapia for Kansas City Royals waivers

The Oakland A’s have added another promising arm to their rebuilding bullpen mix.

The launcher claimed by the A Domingo Tapia excluding Kansas City Royals waivers, the team announced Saturday morning. He was then opted for Triple-A Las Vegas, so he will settle in the minors for now.

Tapia, 30, brings some MLB experience, during which he dazzled the radar with his triple-digit speed. He made his MLB debut in 2020 with five appearances for the Red Sox, then last summer pitched two games for the Mariners before heading to the Royals for another 32 outings.

  • Tapia, MLB 2021: 2.67 ERA, 33⅔ ip, 26 Ks, 15 BBs, 1 HR, 25 hits, 3.35 FIP

Those are solid numbers, backed by a decent xwOBA of 0.303. When asked to protect a lead, he got the hold seven out of 10 with three puffs, which is fixable.

The right-hander is a flamethrower, with a four-seam fastball and sinker that averages over 97mph and tops 100. He hit triple-digits 15 times last year, including a 101mph throw, plus several others in the range above 99. It complements this fire with an effective slider and change that has been knocked down.

It may sound like a batting artist’s power arsenal, but Tapia has never racked up many Ks in his career, not even in the minors. Instead of missing bats completely, he does a better job of missing barrels, inducing grounders and popups that help him limit hits and homers. However, his slider gives him a swing-and-miss weapon, and at his best he can also pump his heat past hitters.

Here’s another look at lead.

Tapia has yet to appear in the majors this season. He started the year on the Royals Triple-A team, pitching five innings with generally solid results before being slated for an assignment last Sunday.

Now he joins the list of 40 A players. To make room, outfielder mickey mcdonalds has been designated for assignment. McDonald was added to the roster last week to help with injuries and made his MLB debut on April 20, eventually appearing in four games and going 0 for 4 with two walks. San Mateo’s local product will now go through waivers, but if it clears that process unclaimed, it’s possible it could remain in Oakland’s system.

The A’s are trying out a lot of new weapons in their bullpen this summer, and the depth chart continues to grow. Before Tapia, they also recovered the right-hander Gabe Klobosits off waivers earlier this month.

Here is the updated list of 40 men. The players listed in -italics have yet to make their majors debut. Players on the 60-day injured list, COVID-related injured list, and suspended list do not count toward the 40-player limit.
