After five excellent months, Dellin Betances has hit a wall in September and hit it hard. He’s allowed 13 runs in 8.1 innings this month while also putting 19 guys on base. Two nights ago Dellin faced three batters and didn’t retire any of them before giving way to Tommy Layne. Opponents have hit .282/.404/.385 against Betances in September. Bad. Bad bad bad.
The biggest problem with Betances, as it often is, are the walks and an overall lack of control. He’s walked eight in 8.1 innings this month after walking 20 batters in his first 63.
