What happened: The veteran left-hander has experienced a sharp statistical regression since changing clubs, a stark contrast to July when Robbie Ray extended a seven-outing run to 5-0. MLB Network analysis indicates his recent difficulties correlate with throwing to varying catchers.
Why it matters: Adjusting to a new backstop midseason can disrupt a pitcher's rhythm and game-planning. The drop in command and run prevention highlights the challenge of integrating a frontline starter into a pitching staff during a playoff push.
By the numbers: Prior to the trade, Ray maintained a 1.29 WHIP and a 1.88 strikeout-to-walk ratio. Those metrics worsened to a 1.46 WHIP and a 1.19 K/BB mark in his subsequent outings.
What to watch: Observers will monitor whether establishing a consistent catcher pairing can help him regain his pre-deadline form.
