A former starter for the White Sox, Angels and Twins, the 31-year-old Santiago joined the Mets on a minor league deal over the winter. Santiago didn’t crack the Mets’ roster at first, instead opening the year at the Triple-A level. He logged a 3.35 ERA/4.94 FIP with 7.95 K/9 and 4.81 BB/9 in 43 innings as a member of New York’s top affiliate before the club summoned him to the majors in late May.
While Santiago has worked as a starter in the minors this season, he functioned exclusively as a reliever with the Mets before they cut him from their 40-man. In eight innings, Santiago allowed six earned runs on 10 hits and five walks (against six strikeouts). Santiago could end up heading back to Syracuse next, though he’ll be able to reject an outright assignment to the minors if he wants.
