Watson, who has struck out seven in five scoreless spring innings, projects as Pittsburgh's primary set-up man once again in 2015. Armed with an electric fastball (94.4 mph) and slider, the lefty gives Pittsburgh a solid late-inning reliever's duo with Mark Melancon. It's probable that save opportunities fall to him if anything happens to Melancon, but manager Clint Hurdle said last summer that he could continue using Watson in high-leverage spots with someone else getting the final three outs. The southpaw, who is working on a tighter-breaking slider this spring, has outpitched his FIP (3.39) with a better earned-run average (2.63) in each of his four big-league seasons.
