Uehara, who will turn 38 years old on April 3, has pitched for four seasons since coming over from Japan. In 2012, he had a 0.639 WHIP in 37 games for the Rangers. In 36 innings (injuries cut his season short), he walked only three batters, while striking out 43.
Peter Abraham says that the Red Sox "have coveted Uehara for years".
Marc Normandin, Over the Monster:
Despite spending his entire career in the AL East and AL West, in parks that favored hitters while in Camden and Arlington, he owns a 2.89 ERA, 153 ERA+, has struck out just under 10 batters per nine innings, and, most eye-poppingly, has punched out eight times as many hitters as he has walked.
