Sept. 17: Arrieta’s strain is a Grade 1 strain, manager Joe Girardi tells reporters (Twitter link via Matt Breen of the Philadelphia Inquirer). He won’t pitch again during the regular season but could still be a potential option in the playoffs, should the Phillies get there.
Sept. 16: The Phillies announced that they’ve placed right-hander Jake Arrieta (right hamstring strain) and outfielder Kyle Garlick (right oblique strain) on the 10-day injured list. Those moves helped clear space for the promotion of outfielder Mickey Moniak. The Phillies also recalled righty Connor Brogdon.
Arrieta’s injury makes it possible that we’ve seen the last of him in a Phillies uniform, as he’s due to reach free agency after the season. The Phillies signed the former NL Cy Young winner and ex-Cubs star to a three-year, $75MM shortly before the 2018 campaign began, but the returns haven’t been positive for the club. Arrieta has missed time with multiple injuries and performed like a back-end starter when healthy, having logged a 4.36 ERA/4.55 FIP over 352 2/3 innings in a Phillies uniform. He has thrown 44 1/3 frames of 5.08 ERA/4.67 FIP ball with 6.5 K/9, 3.25 BB/9 and a 51.8 percent groundball rate this season.
Arrieta’s disappointing production in 2020 is one of the reasons the Phillies are fighting for their playoff lives at 24-23. Aaron Nola and Zack Wheeler have given the team top-level numbers out of its rotation, but Arrieta, Spencer Howard, Zach Eflin and Vince Velasquez have all failed to prevent runs at an acceptable level in a combined 28 starts.
