Tough go for Adam Warren and Dellin Betances last night. They combined for 2 IP, 1 H, 4 BB, and only 1 strikeout from the top of the 6th to the top of the 8th. Each of them failed to finish off the innings they started cleanly after getting 2 outs, and overall they allowed 5 of the 11 batters they faced to reach base. Workload has been a big concern for these 2 for a while now, and in late June the signs of that heavy workload catching up to them started to show:
Warren May- 16.2 IP, 1.62 ERA, 1.78 FIP, 4 BB, 17 K
Warren June- 12.2 IP, 4.97 ERA, 3.41 FIP, 5 BB, 12 K
Betances May- 17.1 IP, 1.04 ERA, 0.96 FIP, 2 BB, 28 K
Betances June- 17.1 IP, 1.56 ERA, 1.60 FIP, 7 BB, 25 K
The splits aren't as drastic with Betances, but both he and Warren took a statistical step back in June from the complete and utter dominance they displayed in May. There is the normalization factor to consider here as a grain of salt. There was no way they were going to keep up May's level of performance for the rest of the season no matter what their workload was. Joe's decision to be more judicious with how he uses them coupled with the change in eye test, however, suggests this is more than just a natural statistical regression. Both guys have had to labor more in their recent appearances and their command has not been as spot on as it was earlier. Their performance for the first few weeks of July is definitely something to keep an eye on.
