Mariners general manager Jerry Dipoto talked to members of the media, including 710 ESPN Seattle’s Shannon Drayer, following the team’s two trades just before Wednesday’s MLB trade deadline.

M’s deadline trades: Leake to Arizona | Elías, Strickland to Nationals

Based off of Dipoto’s comments and additional research, Drayer put together these scouting reports on the four players acquired in the Mariners’ deals that sent Mike Leake to Arizona and Roenis Elías and Hunter Strickland to Washington.

Taylor Guilbeau, LHP, 26 years old

Now ranked the Mariners’ No. 22 prospect on MLB Pipeline. Reporting to Double-A Arkansas. Lower slot lefty, explosive fastball up to 98 mph, averages 95. Above-average slider. Is close to the big leagues. Barring anything unexpected will pitch at the big league level by the end of the season. Running reverse splits in 2020. Mariners do not see him as a situational lefty.

Elvis Alvarado, RHP, 20

Converted outfielder. Fastball up to 100 mph, averages 94, routinely hits 97-98. Still very much a work in progress. Doesn’t yet have command of his weapons but the weapons are significant. Will start in Peoria with the Rookie-level AZL Mariners.

Aaron Fletcher, LHP, 23

Ranked 27th in Mariners’ farm system on MLB pipeline. Throws fastball 90-95 mph, sits at 92. Possesses an above-average slider. Funky delivery. Has started and could start again, although the Mariners see him as a multi-innings reliever. Will report to Double-A Arkansas and possibly play in the Arizona Fall League.

Jose Caballero, 3B, 22

Infielder has mainly played third base but also appears regularly at second and shortstop. Has been out with a wrist injury since late May but will return to play Thursday with AZL Mariners on a rehab assignment. Athletic guy, good shortstop. Stole 28 bases in 43 games before injury this season in High-A. Should report to High-A Modesto in a week.
