Cleveland's Justin Masterson might be a great candidate for a bounce back on the pitching side. Masterson is 0-5 with a 5.87 ERA, but those numbers don't reflect his performance. Masterson is striking out 9.06 per 9 innings (MLB average is 7.07) and has a 62% groundball rate (which is around his career norm).
Given his GB rate, it seems he is the victim of bad luck as his BABIP is .404. His walk rate (4.53 per 9 IP) is a little high, but a 2-to-1 K/BB rate with that GB rate should produce much better results. His GB rate is second best in the bigs and his K/9 rate is 11th. His BABIP is the worst. Of the top 21 in K/9 rate, Masterson is one of only 3 who is stranding fewer than 74% of baserunners, and Masterson's mark is 64.
I wonder if Cleveland's coaches will try to "fix" Masterson because of his ERA. Really, there seems to be nothing to fix other than his luck.
