Prelander Berroa

Mariners Select Four Players

By Steve Adams | November 15, 2022 at 2:19pm CDT

The Mariners announced Tuesday that they’ve selected the contract of righties Prelander Berroa and Isaiah Campbell and outfielders Cade Marlowe and Jonatan Clase. All four are now on the 40-man roster and protected from being selected in next month’s Rule 5 Draft. The quartet of additions fills Seattle’s 40-man roster for the time being.

Each of Berroa (13), Clase (15) and Marlowe (21) rank within the organization’s top 30 prospects, per Baseball America. Mariners president of baseball operations had already confirmed last week that Berroa would be selected to the 40-man roster, though the other additions had not been made public.

Berroa, 22, was acquired from the Giants in a deal that sent infielder Donovan Walton to San Francisco. The Dominican-born righty split the year between the High-A affiliates of the Giants and Mariners before topping out with Seattle’s Double-A club later in the year. In a combined 100 2/3 innings, Berroa posted a 2.86 ERA with a gaudy 36.5% strikeout rate but also a problematic 15.3% walk rate.

Clase, just 20, draws 80-grade reviews for his speed and is considered a potential above-average or better defender in center field. He spent the year in Class-A, hitting .267/.373/.463 with a hearty 13% walk rate but also a more suspect 26.7% strikeout rate. While earlier scouting reports on him suggested he lacked power, Clase smacked 13 home runs in 499 plate appearances and posted a .196 ISO (slugging minus batting average) this season, showing more pop than some might have expected.

Marlow posted an impressive .287/.377/.487 slash with 23 home runs and a whopping 42 steals in 578 plate appearances between Double-A and Triple-A this season. It was an impressive enough showing that he was on the taxi squad and under consideration to make his Major League debut during the playoffs for the Mariners in 2022. The Mariners are expected to add some veteran outfielders this offseason, but Marlowe will be among the options if the team needs to tap into its depth in the event of an injury early in 2023.

Campbell, 25, was the Mariners’ second-round pick in 2019. The 6’4″, 230-pound righty tallied 21 saves and posted a pristine 1.57 ERA with a 33% strikeout rate against a 6.7% walk rate in 46 innings between High-A and Double-A this year.

It’s possible, though not a given, that the Mariners will have further moves in the hours ahead. Seattle is reportedly active on the trade market as teams look to set their rosters in advance of the deadline to protect players from the Rule 5 Draft. Seattle is reportedly open to dealing Jesse Winker on the heels of a disappointing season, and they’ve been receiving interest in fifth-starter candidates Chris Flexen and Marco Gonzales since the offseason began.

Mariners To Select Prelander Berroa

By Anthony Franco | November 8, 2022 at 8:10pm CDT

The Mariners are planning to select right-hander Prelander Berroa onto their 40-man roster, president of baseball operations Jerry Dipoto tells reporters (including Ryan Divish of the Seattle Times). The 22-year-old would otherwise be eligible for the Rule 5 draft this winter, and Seattle will keep him away from other clubs by adding him to the 40-man.

Seattle acquired Berroa in May, adding him from the Giants in a deal that sent utilityman Donovan Walton to San Francisco. It was the second trade of Berroa’s young career, as he’d previously gone from the Twins to the Giants in a 2019 deadline deal. A native of the Dominican Republic, Berroa draws praise from evaluators for his fastball-slider combination but has some questions about his control.

That was mostly borne out in his 2022 numbers. Berroa split his time between High-A and Double-A, starting all 26 of his appearances. He posted a cumulative 2.86 ERA through 100 2/3 innings, striking out an incredible 36.5% of batters faced. He also walked an elevated 12.6% of opponents, highlighting that his strike-throwing remains a work in progress. Nevertheless, the M’s feel there’s a chance another club would’ve plugged Berroa directly onto the MLB roster next year given the quality of his stuff.

Giants Acquire Donovan Walton, Designate Mike Ford

By Anthony Franco | May 11, 2022 at 3:06pm CDT

The Giants have acquired infielder Donovan Walton from the Mariners in exchange for pitching prospect Prelander Berroa, according to announcements from both teams. San Francisco has designated first baseman Mike Ford for assignment to clear space on the 40-man roster.

Walton, 28 later this month, has appeared in the majors in each of the past four seasons. He’s tallied just 102 cumulative plate appearances across 37 games, though, and his only MLB outing this year saw him enter as a pinch-runner. A left-handed hitter, Walton has posted a modest .196/.260/.315 showing in the majors.

The Oklahoma State product has a more robust body of work in the minors, where he’s a .287/.375/.427 hitter in parts of six seasons. That includes a .302/.391/.518 line in just shy of 400 trips to the plate at Triple-A, and Walton’s hitting .294/.368/.510 through 12 contests there this season. Perhaps of greatest import to the Giants, he’s a versatile defender who has a ton of professional experience in the middle infield. He figures to bounce around the diamond in a utility capacity for a Giants team that has dealt with injuries to both Evan Longoria and Tommy La Stella (although Longoria is making his season debut today). Walton is in his final minor league option year, meaning the Giants can shuttle him between San Francisco and Triple-A Sacramento for the remainder of the season if he sticks on the 40-man roster.

Walton, somewhat ironically, becomes the third infielder the Giants have acquired from Seattle in as many weeks. San Francisco also picked up Kevin Padlo on April 26 and acquired Ford on April 30. Both those deals were for cash considerations, but the M’s recoup a minor league arm in exchange for Walton.

Berroa, a 22-year-old righty, originally signed with the Twins as an amateur out of the Dominican Republic. San Francisco acquired him at the 2019 trade deadline, and he’s spent the past few seasons in the lower levels of the farm system. Baseball America named Berroa the #29 prospect in the Giants’ system over the offseason, writing that he owns a mid-upper 90s fastball and a solid slider. The outlet suggested Berroa’s control is a work of progress but that he has a chance to develop into a back-of-the-rotation starter.

Over four appearances with High-A Eugene this season, Berroa has worked 13 1/3 innings of one-run ball. He has 16 punchouts and six walks, a continuation of the high-strikeout, high-walk ways he’s shown throughout his young career. Berroa will be eligible for the Rule 5 draft this winter if he’s not added to the Mariners’ 40-man roster.

Ford, meanwhile, suited up in just one game in black and orange. He collected a single in four plate appearances and has a .271/.417/.417 line over 60 Triple-A plate appearances this season. It’s the second time this year that Ford has been designated for assignment, as a DFA preceded the aforementioned trade from Seattle to San Francisco. The Giants will have a week to trade the 29-year-old or try to run him through outright waivers.
