The 31-year-old Aceves split last season between the Boston Red Sox and Triple-A Pawtucket. He was 4-1 with a 4.86 ERA in 11 games (six starts) last season with the Red Sox and 4-2 with a 4.25 ERA in eight starts with 48 2/3 innings at Triple-A Pawtucket.
Over his six-year career in the major leagues, Aceves has been mostly a reliever. He has a 30-14 career record with a 3.69 ERA and 29 saves -- including 25 in 2012 with Boston.
In August 2012, the Red Sox suspended Aceves for three games for conduct detrimental to the team following a confrontation with then-manager Bobby Valentine. Later that year, he was involved in an heated argument with Red Sox second baseman Dustin Pedroia during a game in Oakland.
While pitching for Mexico during last year’s World Baseball Classic, Aceves was ejected following a brawl in a game against Canada in which he was shown throwing punches.
