The Boston Red Sox optioned right-handed pitcher Marcus Walden to Triple-A Pawtucket following today’s game against the Baltimore Orioles. A corresponding move to fill his spot on the 25-man roster will be made tomorrow.

President of Baseball Operations Dave Dombrowski made the announcement.

Walden, 30, has made five relief appearances for Boston this season after being recalled from Triple-A Pawtucket on April 6th. The right-hander was 2-0 with a 3.38 ERA (3 ER/8.0 IP) and limited opponents to a .167 batting average (5-for-30) with the big league club, with three of his appearances being 2.0 innings. Walden earned his first major league win in his season debut in the club’s 1-0 victory on April 7 at Arizona. In 13 career major league appearances, all with Boston, Walden is 2-0 with one save and a 3.57 ERA (9 ER/22.2 IP).
