Through eight big league starts with the Cincinnati Reds, Luis Castillo has posted a 3.56 ERA in 48.0 innings. He’s given up 39 hits and walked 18 batters in that span to go with 51 strikeouts. There are 186 starting pitchers with at least 40.0 innings this season. Luis Castillo leads that group with the highest average fastball velocity at 97.7 MPH.

What has been rather interesting to see in the stats, though, is the batted ball change from his time in Double-A to his time in the Major Leagues. With the Double-A Pensacola Blue Wahoos in the first part of the season he made 14 starts. His ground ball rate there was just 39%. In his eight big league starts, Luis Castillo has posted a ground ball rate of 58%. Prior to reaching Double-A, his minor league ground ball rates were always hovering in that 50% range. His new rate is not terribly out of the norm for his career – but for it to jump up at such a high rate within the same season is rather interesting. What’s even more interesting is that it’s come without the usage of a 2-seam fastball until his most recent start.

With two more innings in the Major Leagues, Luis Castillo will lose his prospect eligibility. He’s seemingly been underrated since joining the organization. Heck, the Marlins traded the guy TWICE in the last year. He first went to the Padres in 2016 a few days before the trade deadline. However, he was returned when Colin Rea was immediately injured and the Padres called foul on the Marlins. The two teams then agreed to “trade” Rea and Castillo for each other to make things “good”. The Marlins traded him to Cincinnati in January as a part of the Dan Straily trade.

Foolishly, I ranked him 9th on my prospect list before the 2017 season began based on the fact that he had never made it a full season with a big workload. After seeing him pitch on a consistent basis in the 1st half, I moved him up to #2 in the system. This season he’s at 128.1 innings between the two stops, which is just behind where he finished in 2016 (131.2 innings). He will certainly pass that up and continue towards a full seasons workload moving forward over the final two months.

Other notes from around the Cincinnati Reds system

There was a lot of happenings yesterday. In case you missed them, here’s a quick rundown: Jose Siri set a new Midwest League Record by extending his hitting streak to 36 games (and he just doubled in the 1st inning today to make it 37 games) and the Reds traded Tony Cingrani to the Dodgers and acquired two minor leaguers – including catcher Hendrik Clementina.

The Pioneer League vs Northwest League All-Star game takes place tonight. It will feature Hendrik Clementina, as well as three other Billings Mustangs. Pitchers Packy Naughton and Moises Nova, along with outfielder Miles Gordon will participate. The game will be on MiLB.tv at 10:05pm ET if you have that service.

Cincinnati Reds General Manager Dick Williams joined local sports talk radio host Lance McAlister to talk about the trade of Tony Cingrani as well as other trade deadline kind of stuff. One of the important non-trade things that he spoke about was Jesse Winker. Williams noted that it’s getting to be the time where they get him some time at the big league level because he’s earned it. Give it a listen below.
