Red Sox left-handed pitching prospect Trey Ball threw five shutout innings for Low-A Greenville on Saturday, striking out four and allowing two hits.
Ball has had a brutal season after an aggressive assignment to the Low-A South Atlantic League, as opposing batters have hit .317/.376/.481 against him, but he has pitched much better as of late. Over his last four starts, he has held opposing batters to a .171/.247/.257 line with a 7.6 K/9. The 6'6" lefty has front of the rotation upside, but was considered one of the most raw pitchers in the draft. His last few starts have been a great step in the right direction, and he should open 2015 with High-A Salem.
