The Yomiuri Giants announced Saturday that they have agreed to contract terms with 30-year-old right-hander Rubby de la Rosa.

De la Rosa last played in the majors in 2017 and has a career big league record of 26-30 with a 4.49 ERA. This year with the Reno Aces, the Arizona Diamondbacks’ Pacific Coast League farm club, de la Rosa has throw 21-2/3 innings over 18 games. He has struck out 29 batters, while walking seven.

The Giants’ bullpen appeared settled this season with the return of right-hander Scott Mathieson from knee surgery and the addition of Ryan Cook, who started the season as the Central League club’s closer. But Mathieson’s season has been stalled by illness, while Cook has only recently returned after feeling discomfort in his surgically repaired right elbow.

The closer’s role has fallen to 25-year-old lefty Kota Nakagawa, who was thrown into his first save situation on April 17, and has a 1.25 WHIP this season in 16 save opportunities with a 2-1 record, four holds and nine saves.
