Bristo struck out four and walked one over three hitless innings Thursday, earning a save in a 9-3 victory over the Red Sox.
While Bristo shouldn't be expected to receive many three-inning save opportunities, it was quite a debut for the 28-year-old right-hander. Despite the impressive performance, Bristo likely won't serve more than an occasional long-relief role in Tampa Bay. He posted a 4.56 ERA in 53.1 innings last season with Triple-A Scranton-Wilkes-Barre before signing a minor-league deal with the Rays in January.
