After Junichi Tazawa walked four batters in a row on Friday, the Boston Red Sox looked for another option at closer.

Torey Lovullo announced on Sunday morning that Jean Machi would be the club's closer going forward. The Red Sox added Machi in late-July via a waiver claim from the San Francisco Giants.

Koji Uehara, Boston’s closer for the last three seasons, is out for the year with a fractured right wrist.

Machi, a 33-year-old right-hander, is 3-for-3 in save opportunities for the Red Sox, working a 1-2-3 ninth in a 3-1 victory Saturday.
