Santillan has been dominant at Double-A Pensacola since his promotion, including a 5.2 inning scoreless outing Monday night where he struck out 11 batters, the Reds' official site reports.

EDGE Analysis

Overall, Santillan has a 1.84 ERA in five outings for Pensacola over 29.1 innings, with a 32:7 K:BB ratio and just one homer allowed. RotoWire rates Santillan as the Reds' #8 prospect.

Santillan was promoted to Double-A Pensacola on Thursday, Doug Gray of RedsMinorLeagues.com reports.

EDGE Analysis

Santillan advanced to the next level within the Reds' minor-league system after posting a 2.70 ERA and 1.19 WHIP with a 73:22 K:BB over 86.2 innings this season at High-A Daytona.

Santillan gave up one run on six hits and a walk and struck out six over 6.2 innings to pick up the win Sunday for High-A Daytona in the club's 5-1 victory over Dunedin.

EDGE Analysis

The right-hander cruised through the first five frames before allowing a solo home run to the leadoff batter in the bottom of the sixth, ending a streak of 21 scoreless innings to begin the season. Santillan escaped the sixth without any further damage and retired the first two hitters in the bottom of the seventh before departing, bringing his ERA down to 0.40 for the season. The 21-year-old has supported the stellar ERA with a 4.8 K/BB, doubling the rate he submitted in what was a solid season at Low-A Dayton in 2017.

Santillan tossed six scoreless innings Wednesday, allowing one hit and two walks while striking out eight for High-A Daytona.

EDGE Analysis

He has 13 strikeouts and has not allowed a run through 10 innings to start the season. The hard-throwing righty has almost given up as many walks (four) as hits (five), which matches his reputation as an electric starter with shaky command/control who may eventually need to move to the bullpen. He turns 21 on April 15, and should continue to put up impressive numbers in the pitcher-friendly Florida State League.

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.
