Gregory Santos Could See Himself Sent Down to Triple-A Soon For Seattle Mariners

Santos, thought to be a high-leverage arm when he was acquired before the 2024 season, continues to struggle and could end up needing time in the minors to rectify things.

When the Seattle Mariners acquired hard-throwing reliever Gregory Santos from the Chicago White Sox before the 2024 season, the M's thought they were getting a power arm to use in high-leverage situations alongside Matt Brash and Andres Munoz.

Unfortunately, Brash missed the entire season with Tommy John surgery and Santos missed most of the season with various ailments. This year, Santos hasn't been the arm the M's were hoping for thus far and he could find himself getting sent to the minors to figure things out.

Brash should be back from his surgery within the next few weeks, so maybe Santos could hold on until then, but with a minor league option remaining, he could get sent down earlier.

The 25-year-old Santos lasted just 0.1 innings in relief on Tuesday, surrendering two earned runs on one hit and three walks against the Cincinnati Reds. He has an ERA of 5.14 through eight games. He's carrying a WHIP of 2.29 and has yet to strike out a single batter in 7.0 innings.

Lifetime, he's 3-6 with a 4.17 ERA, appearing in games for the San Francisco Giants, White Sox and Mariners.

The M's enter Wednesday's game with the Reds at 8-9 overall. Cincinnati is 9-8.

The two teams will play at 3:40 p.m. PT as the M's send Bryce Miller to the mound against Nick Martinez. Both pitchers have struggled in the early going, with Miller sitting at 0-2 with a 4.50 ERA. Martinez is 0-2 as well and he owns a 6.06 ERA.
