The Boston Red Sox have placed veteran pitcher Sonny Gray on the 15-day injured list due to a right hamstring strain. This injury occurred during the Patriots' Day game against the Detroit Tigers when Gray felt tightness in his hamstring after throwing a pitch. The 36-year-old right-hander, acquired from the St. Louis Cardinals in November, has a 2-1 record with a 4.30 ERA in five starts this season. To fill his spot on the roster, the Red Sox recalled Tyler Samaniego, a 27-year-old left-handed pitcher, from Triple-A Worcester. Samaniego has made a solid impression in his brief appearances, throwing 3 2/3 hitless innings with three walks and four strikeouts. The Red Sox, who are struggling with a 9-13 record, are set to face the New York Yankees in their next series.
