The Phillies are set to promote promising young right-hander Enyel De Los Santos, as first reported by Tom Housenick of the Morning Call (via Twitter). He’ll make his Major League debut when he starts Tuesday’s game. The promotion will require the Phillies to formally select De Los Santos’ contract, so Philadelphia will need to make a 40-man roster move, though they have a clear 60-day DL candidate in Pedro Florimon, who has already been out since May 30 due to a broken foot and has yet to begin a minor league rehab assignment.
De Los Santos, 22, was acquired from the Padres in the offseason trade that sent Freddy Galvis to San Diego. It seemed a fairly steep price for the Padres to pay in exchange for Galvis at the time, as De Los Santos is a generally well-regarded arm and was coming off a solid 2017 season in Double-A. This season, De Los Santos entered the year ranked as the Phillies’ No. 11 prospect, per MLB.com, and all he’s done since that time is elevate his stock.
Though De Los Santos is roughly four years younger than the average player in the Triple-A International League, he’s currently sporting a league-leading 1.89 ERA through 95 1/3 innings of work. He’s averaged 8.2 K/9, 2.9 BB/9 and 0.94 HR/9 to go along with a 42.1 percent ground-ball rate through his 16 starts, and he was recently named to the MLB Futures Game.
Jim Callis and Jonathan Mayo of MLB.com note in their free scouting report on De Los Santos that the righty sits 94-95 mph on his heater and can reach 97-98 mph at times. De Los Santos thrives on missed bats and weak contact with that fastball and a plus changeup, though his curveball is a less-effective third pitch and still needs work to be considered Major League average.
De Los Santos will step into the MLB rotation for now alongside Aaron Nola, Jake Arrieta, Zach Eflin and Nick Pivetta, though it’s not immediately clear if he’ll simply be making a spot start or if he’ll receive further chances beyond Tuesday’s outing while Vince Velasquez mends from a forearm contusion. The Phils are playing a doubleheader against the Mets today, and threw rookie Drew Anderson in his own MLB debut on Sunday, so their pitching mix is currently a bit jumbled.
