Reds promote Christian Roa to Triple-A Louisville

A few days age we found out that top 10 prospects Connor Phillips and Noelvi Marte were both being promoted from Double-A Chattanooga to Triple-A Louisville now that the first half of the season is over. This morning we found out that the first-half winners in the Southern League would be losing another player to promotion, with right-handed starting pitcher Christian Roa joining them.

For the first half of the season, Christian Roa was in Chattanooga’s rotation. He made 13 starts and posted a 4.88 ERA. Over his 59.0 innings pitched he allowed 41 hits, seven home runs, walked 44 batters, and he struck out 87.

On the good side of those stats is that he’s not allowing many hits and he’s picking up a lot of strikeouts. On the flip side of that is that his walk rate is about twice as high as you’d prefer to see it from a starting pitcher. That walk rate is going to have to come down if he’s going to remain a starting pitcher in the long run.

The season has been up-and-down for Roa. His first start of the year saw him allow five earned runs and not get out of the 1st inning. The next three starts were better, but not good, as he allowed 11 runs in 11.2 innings and had 11 walks, and hit three more. But he was absolutely dominant in the three starts that followed that, giving up just four hits in 15.0 innings and allowing no earned runs while striking out 24 batters (but did have 10 walks). Things got tough in the following three starts as he allowed 14 runs in 14.2 innings. But once again he was dominant in the following three (and final) starts. He gave up just two runs in 17.0 innings and allowed just eight hits (but walked 11 batters). You can see his career stats here.

With Double-A experimenting with the pre-tacked ball in the first half of the season, it’s been tough to truly evaluate pitchers (and hitters, to be honest). Triple-A uses the major league baseball. It’s not pre-tacked. We’ll get a little better idea due to that, but with that it also comes better hitters. It also comes with the automated strikezone for half of each series, and a challenge system for the other half.

As I type this, no other promotions in the system have been announced, but they have to be coming. The trickle up effect to fill out the rosters is going to happen.
