Mariners Select Leo Rivas, Place J.P. Crawford On Injured List

The Mariners have placed shortstop J.P. Crawford on the 10-day injured list with a right oblique strain, per a team announcement. Infielder Leo Rivas’ contract has been selected from Triple-A Tacoma, and he’ll take Crawford’s spot on the roster. Righty Gregory Santos was transferred from the 15-day IL to the 60-day IL in a corresponding move. More specifically, Crawford tells Ryan Divish of the Seattle Times that he’s dealing with a Grade 1 strain (X link).

Crawford was scratched from yesterday’s game after experiencing tightness in his right oblique. He was sent for an MRI that revealed the strain. The Mariners haven’t provided a timetable for his return, but even Grade 1 strains — the least severe — of an oblique can sideline players for upwards of a month. Manager Scott Servais said prior to today’s game that utilityman Dylan Moore will be in line for the bulk of the shortstop reps while Crawford is on the shelf (X link via Divish).

The timing of Crawford’s injury is unfortunate. He’d gotten out to a slow start in 2024 but had just begun to turn the tides, hitting safely in nine of his past ten games and batting .275/.383/.360 during that span. He’s still hitting just .198/.296/.302 on the whole but had clearly been trending in the right direction prior to sustaining the injury.

Crawford’s absence will cost the Mariners their everyday leadoff man and shortstop. He’s emerged as a consistent presence atop the lineup, slashing .262/.352/.384 from 2021-23 while playing sound defense at shortstop (where he won a Gold Glove in 2020). Swapping him out for the 31-year-old Moore is likely a downgrade on both sides of the ball.

While Moore has plenty of experience at shortstop — and at nearly every position on the diamond — it’s his weakest position by measure of both Defensive Runs Saved and Outs Above Average. Moore is a .217/.344/.398 hitter since 2022 (118 wRC+), but that production has come with the benefit of being heavily platooned; he won’t have that luxury in an everyday role and figures to face plenty of right-handers, against whom he’s just a .198/.302/.368 hitter.

Rivas, 26, is receiving his first call to the bigs. The Mariners are his third career organization, as he was originally signed by the Angels as a teenager and has also spent time with the Reds. He’s out to a strong start in Triple-A Tacoma, where he’s posted a .308/.422/.462 slash in 66 trips to the plate. Getting on base has never been an issue for Rivas in the minors, where he touts a career .378 OBP. He lacks power, however, evidenced by a career-high of seven homers and a lifetime .106 ISO (slugging minus average). Divish notes that Servais touted Rivas’ defense multiple times as a reason that he was given the call in the wake of Crawford’s injury.
