Now, it appears increasingly likely that the role is one in which Uehara may contribute not just for the rest of this season but also for next. According to an industry source, Uehara’s one-year, $4.25 million deal included a $4.25 million vesting option for the 2014 season that becomes guaranteed when he pitches in 55 games; incentives can push the value of the deal to $5 million with 35 games finished.
Uehara has been nothing short of dominating during his first season in Boston, posting a video game-like 1.35 ERA and 0.69 WHIP in 53.1 innings. Potentially more impressive is his batting average against where the Osaka native has held opposing batters to a nearly unheard of .151 average.
For a paltry $4-5 million dollars, the Sox are sitting on one of the best bargain for production contracts in Major League Baseball.
