The Miami Marlins are once again shaking up the bullpen. The Fish just made a change a few days ago, and some other changes due to injuries earlier. This time The Fish demoted just promoted lefty relief pitcher Enmanuel De Jesus to AAA Jacksonville. In his place, The Fish called another lefty relief pitcher back up to the Major League team. The pitcher? Daniel Castano. How good is this move?

The Miami Marlins once again shook up the bullpen.

Enmanuel De Jesus was making his Major League debut at the late age of 26. De Jesus has a 4.86 ERA in A and AAA this season, produced in 18 games and 87.0 innings pitched. He also has 6.9 K/9 and 5.1 BB/9 rates in the Minor Leagues this season. Was he able to pitch better at the Major League level? In just a game and 4.1 innings pitched, he has a 6.23 ERA/3.95 FIP, with 6.2 K/9 and 4.2 BB/9. It's obvious that the ERA and the walks rate were not good. That said, the FIP is promising and the K/9 isn't that bad.

Was it too early to give up on De Jesus? It certainly seems that way to me. Is his replacement really that much better? The replacement as previously mentioned is Daniel Castano. Castano has actually pitched for The Fish every season since 2020. In that time he compiled a 4.15 ERA/5.13 FIP, with 4.9 K/9 and 3.0 BB/9. That's also around how he pitched in the Minor Leagues this season.

Do you remember him being up earlier this season? Well, he was and delivered a 27.00 ERA/28.26 FIP, with 18.0 K/9 and 9.0 BB/9 in a game and an inning pitched. Last season he had a 4.04 ERA/4.74 FIP, with 5.0 K/9 and 2.3 BB/9 in 10 games and 35.2 innings pitched. It's pretty obvious that there's nothing really impressive about those results. Will the 28 year old do better this time around? I don't have much hope for that unfortunately. I don't see why De Jesus couldn't have received more innings first.
