Julian Tavarez is confident with Boston's starting rotation and feels like they don't need to add Roger Clemens. ?I don?t think we need him,? said Tavarez before the Red Sox? game against Oakland last night at Fenway Park [map]. ?Anybody could use (Clemens), but I don?t think we need him.? Clemens, who has been working out with the Houston Astros, informed his agents, Randy and Alan Hendricks, that he will make his decision on where he will play this season by the end of the month. The candidates are Houston, the Yankees and the Sox. Last year, Clemens signed with the Astros on May 31.
