Walters will serve as the Guardians' opening pitcher in Wednesday's contest versus the Reds, Zack Meisel of The Athletic reports.

The Guardians are altering their final-week pitching plans after locking up a first-round bye in the playoffs. Walters will serve as the Guardians' first pitcher in what's expected to be a bullpen game in the series finale Wednesday, with Joey Cantillo's next start being pushed back to Friday against the Astros as a result.
