A year after their record-setting, World Series championship season, the Boston Red Sox are looking for meaning wherever they can find it. Long ago finished in the AL East race and on the verge of wild-card elimination as well, the defending champs managed to keep alive Eduardo Rodriguez's chances of a 20-win season, barely saving his 18th victory while beating the San Francisco Giants 5-4 on Thursday. ''There was a lot of talk about that,'' said manager Alex Cora, who led the team to 108 wins and the title in his first season on the bench.
