Seattle Mariners Bring Up Exciting Pitching Prospect to Aid Bullpen

Perroa is the team's No. 13 prospect currently and there's been talk that he could be the organization's next Edwin Diaz, who was with the Mariners before being traded to the Mets.

The following comes from a portion of his MLB.com prospect profile:

A case could be made that Berroa might have the best raw stuff in the pipeline, with a top-end fastball-slider combination. Originally signed as an infielder for $200,000 with the Twins in 2016, he then landed with the Giants, who flipped him to the Mariners in 2022 for infielder Donovan Walton, a deal that could be a huge long-term win for Seattle if he stays at this pace.

Berroa’s heater sits in the mid-90s and has touched 99-100 mph with seamless arm-side run, and the slider sits at 82-85 mph possessing a shorter, cutter-like shape; both generate a ton of whiffs and groundouts. He also has a changeup in his back pocket, but he can throw it too hard at times, thus making it hittable. The power profile behind his two best pitches, not to mention command issues, suggests he might be destined for relief long term.

Diaz became a reliever and made his debut with the Mariners in 2016, saving 18 games in 49 appearances. In 2017, he had 34 saves and in 2018, he led baseball in saves with 57.

He was traded to the Mets before the 2019 season in the deal that brought Jarred Kelenic to Seattle.

The Mariners will take on the Minnesota Twins on Wednesday night. First pitch is 9:40 p.m. ET.
