BOSTON, MA—The Boston Red Sox today added right-handed pitcher Mauricio Llovera to the active Major League roster. To make room for Llovera, the club optioned left-handed pitcher Joe Jacques to Triple-A Worcester following last night’s game against the San Francisco Giants. Llovera will wear number 68.

Chief Baseball Officer Chaim Bloom made the announcement.

Llovera, 27, was acquired from the Giants on Wednesday, in exchange for minor league right-handed pitcher Marques Johnson. He has posted a 1.69 ERA (1 ER/5.1 IP) in five games for San Francisco this season, all in relief. The right-hander has also recorded a 3.92 ERA (9 ER/20.2 IP), 1.06 WHIP, and .211 opponent batting average (16-for-76) with six walks and 24 strikeouts in 17 games (two starts) for Triple-A Sacramento in 2023. Signed by the Philadelphia Phillies as a non-drafted free agent on December 14, 2014, the Venezuela native owns a 6.14 ERA (20 ER/29.1 IP) in 29 career Major League games (one start) with the Phillies (2020-21) and Giants (2022-23).

Jacques, 28, has posted a 4.86 ERA (9 ER/16.2 IP) in 14 appearances (one start) for Boston this season, the first Major League outings of his career. In 23 games with Triple-A Worcester (one start), the left-hander has recorded a 3.58 ERA (11 ER/27.2 IP). Originally selected by Pittsburgh in the 33^rd round of the 2018 First-Year Player Draft out of Manhattan College, the New Jersey native was acquired by the Red Sox in the Triple-A phase of the 2022 Rule 5 Draft.
