Red Sox Triple-A (Worcester)

Rio Gomez was promoted to Triple-A on Saturday and promptly made his Triple-A debut. Getting the start, the left-handed pitcher looked strong in his first outing for Worcester. He allowed one run on three hits over 4 1/3 innings. Gomez walked three batters but struck out three as well. He's one of the easiest players to root for. I love this for him.

Shane Drohan had a much better week. The left-handed pitcher made two starts, combining to allow three earned runs over 11 innings. He walked 10 but only gave up eight hits and struck out eight batters. Drohan has needed to adjust to Triple-A, but it looks like he's starting to come around.

Theo Denlinger was promoted to Triple-A and allowed five runs over 3 2/3 innings. The righty reliever walked five batters, which caused most of his problems. Denlinger dominated in Double-A, so a rough first two outings shouldn't cause any worry.

Chris Murphy was moved to the bullpen and immediately showed out. The left-handed pitcher tossed three shutout innings. Murph only surrendered one hit. He also had his first outing of a year without walking anyone and still managed to strike out three. His pitch mix might work perfectly in the bullpen.

Christian Koss got bumped up to Triple-A after starting to heat up in Double-A. The right-handed hitting shortstop is 3-for-14 with a walk and two doubles. Koss drove in a run and scored two more.

Ryan Fitzgerald hasn't stopped mashing in Triple-A this season. The left-handed hitting utility is slashing .310/.385/.563 with 14 doubles, one triple, and eight home runs. He's driven in 38 runs, scored 26 more, and stolen five bases. Fitzy is such an incredible depth piece for the Red Sox. Sadly, though, he probably won't get used by Boston.
