BOSTON, MA—The Boston Red Sox today signed right-handed pitcher Liam Hendriks to a two-year contract through the 2025 season, with a mutual option for 2026. He will wear number 31. Boston’s 40-man roster is now at 40.

Hendriks, 35, is the reigning American League Comeback Player of the Year, a two-time Mariano Rivera American League Reliever of the Year (2020-21), three-time American League All-Star (2019, ’21-22), and three-time All-MLB selection (2019-21). The right-hander owns a 3.82 ERA (276 ER/650.0 IP) with 116 saves and 727 strikeouts in 476 career games (44 starts) with the Minnesota Twins (2011-13), Kansas City Royals (2014), Toronto Blue Jays (2014-15), Oakland Athletics (2016-20), and Chicago White Sox (2021-23). Since the start of 2019, he leads American League relievers (min. 200.0 IP) in WHIP (0.89), strikeout-to-walk ratio (7.54), and walks per 9.0 innings pitched (1.77) and ranks second in ERA (2.32) and opponent OPS (.551).

In December 2022, Hendriks was diagnosed with Stage 4 non-Hodgkin’s lymphoma, a blood cancer that he believes he had been pitching with during the 2022 season when he posted a 2.81 ERA with 37 saves in 58 appearances for the White Sox. After undergoing eight rounds of chemotherapy—which began in January 2023 and ended in April—and four rounds of immunotherapy, Hendriks began a rehab assignment on May 5 before returning to the majors on May 29. He appeared in five games with the White Sox, earning two wins and one save before being sidelined by an elbow injury. He earned the Jimmy V Award for Perseverance at ESPN’s annual ESPY Awards in July and in November he received the 2023 Tony Conigliaro Award, presented by the Red Sox to a “Major Leaguer who has overcome adversity through the attributes of spirit, determination, and courage that were trademarks of Tony C.”

A native of Perth, Australia, Hendriks launched a campaign inviting fans to purchase specially designed “Close Out Cancer” t-shirts, with proceeds benefitting the Lymphoma Research Foundation. He has been nominated for the prestigious Roberto Clemente Award five times, including twice by the A’s (2017, ’19) and three times by the White Sox (2021-23).
