The Mariners announced that they have selected the contract of left-hander Hector Santiago and designated righty Sam Delaplane for assignment. In other moves, the club recalled lefty Daniel Zamora, and it optioned righties Wyatt Mills and Yohan Ramirez.
Santiago, whom the Mariners signed to a minor league contract earlier this season, will now have an opportunity to appear in the majors for a 10th year. The 33-year-old is best known for a productive run with the White Sox and Angels from 2011-15, but his numbers have fallen off since then among a few teams. He most recently pitched in the majors in 2019 between the White Sox and Mets, with whom he combined for a 6.68 ERA/4.89 SIERA in 33 2/3 innings (most of which came in relief). Santiago has thrown 14 frames with the Mariners’ Triple-A affiliate this year and yielded seven earned runs on 10 hits (including five home runs) with an eyebrow-raising 22 strikeouts against five walks.
Delaplane, 26, has been with the Mariners since they chose him in the 23rd round of the 2017 draft. He has since posted impressive minor league production, including a stunning 0.49 ERA with a similarly excellent 43.3 percent strikeout rate against a 6.7 percent walk rate during a 37-inning Double-A debut in 2019. However, with Delaplane having undergone Tommy John surgery in April, Seattle doesn’t believe he’s worth a 40-man roster spot at this point.
