The Boston Red Sox today added right-handed pitcher Nathan Eovaldi to the active major league roster. He will wear number 17. To make room, the club optioned right-handed pitcher Brandon Workman to Triple-A Pawtucket. 
President of Baseball Operations Dave Dombrowski made the announcement.
Eovaldi (ee-VAUL-dee), 28, was acquired by the Red Sox yesterday from the Tampa Bay Rays in exchange for minor league left-handed pitcher Jalen Beeks. The right-hander went 3-4 with a 4.26 ERA (27 ER/57.0 IP) and a 0.98 WHIP in 10 starts for the Rays this season, striking out 53 batters and walking only eight. He most recently pitched Friday against the Miami Marlins and did not factor into the decision, allowing one run in 6.0 innings with eight strikeouts and zero walks. Among pitchers with at least 50.0 innings in 2018, Eovaldi owns the American League's third-highest strikeout-to-walk ratio (6.63) behind only Corey Kluber (7.44) and Justin Verlander (7.04). He has held right-handed hitters to a .207 batting average (24-for-116) and a .217 on-base percentage with 29 strikeouts against only two walks.
Workman, 29, has made 21 appearances for Boston this season, going 2-0 with a 2.89 ERA (6 ER/18.2 IP), a .217 opponent batting average, a 1.02 WHIP, 19 strikeouts, and four walks. Prior to being recalled by the Red Sox on June 5, the right-hander posted a 4.18 ERA (13 ER/28.0 IP) in 15 games for Pawtucket. After undergoing Tommy John surgery in June 2015, Workman returned to the majors in 2017, recording a 3.18 ERA (14 ER/39.2 IP) in 33 relief appearances and earning the Red Sox Comeback Player of the Year Award from the Boston Baseball Writers. A member of the Red Sox' 2013 World Series championship club, he has made 93 appearances (18 starts) over parts of four major league seasons (2013-14, '17-18).
