The Boston Red Sox tried to bolster their bullpen with yet another left-hander, getting Mike Remlinger and cash from the Chicago Cubs on Tuesday for minor league pitcher Olivo Astacio. The AL East-leading Red Sox cut lefties Alan Embree and John Halama last month. Remlinger was designated for assignment by the Cubs last Friday. Remlinger, 39, was 0-3 with a 4.91 ERA in 35 games. He was sidelined from May 21 to June 5 because of a broken finger on his left hand. He was especially effective against righty hitters, holding them to a .210 batting average. Remlinger had been one of the more reliable and durable lefty setup men in recent years. He was an NL All-Star in 2002 with Atlanta, which came during a stretch in which he made at least 70 appearances in five straight seasons.
