Santillan has thrown 11 consecutive scoreless innings for Low-A Dayton, including five shutout frames Friday against Fort Wayne, where he struck out eight.

EDGE Analysis

So far this is the best campaign for Santillan, who has a 2.68 ERA and 1.16 WHIP with Dayton. He still walks too many batters (3.7 per nine innings at Dayton), but his strikeout rate has climbed and he's cut down on his homers allowed as well.

Santillan (shoulder) picked up the win in his return from the disabled list Friday, allowing three runs in 6.1 innings pitched while fanning seven and walking just one batter.

EDGE Analysis

Santillan ultimately only had to miss one start due to this shoulder issue, and it also doesn't seem to have any lingering effects. He'll continue to develop in Low-A Dayton's rotation with the hopes of improving his control and maintaining his position in the organization as a legitimate rotation prospect.

Santillan was placed on the 7-day DL on Thursday at Low-A Dayton with shoulder stiffness.

EDGE Analysis

The big righty's stuff has always been filthy, with the potential for two plus-plus pitches in his fastball and curveball, and he had finally started to make major improvements to his control this season before the injury. After posting a 17.4 percent walk rate in 30.1 innings at Low-A last year, he had managed a 9.5 percent walk rate in 58.2 innings this season. He is still walking too many hitters, but at least he is now in a range as a 20-year-old that allows evaluators to give him a chance of ending up in the rotation long term. Hopefully this injury is just stiffness, and he can return to the mound and pick up where he left off in the coming weeks.
