The Phillies have placed outfielder Nick Castellanos on the 10-day injured list. Outfielder Dalton Guthrie had his contract selected from Triple-A and another 40-man roster move will be necessary to accommodate Guthrie’s addition to the active roster.

Castellanos left Friday’s game due to an oblique injury, with manager Rob Thomson saying that the outfielder would undergo an MRI to determine the extent of the problem. There hasn’t been any word on the results of the MRI, but even a lower-level oblique problem usually results in at least a minimal IL visit. Castellanos and the Phillies can only hope that the injury is minor, as otherwise Castellanos could be in danger of missing the rest of the regular season and possibly the playoffs.

It has been an underwhelming season overall for Castellanos, who signed a five-year, $100M free agent deal with Philadelphia in March. The slugger is hitting only .265/.305/.397 over 531 plate appearances, resulting in a subpar 96 wRC+. However, Castellanos has looked a lot more like his old self in recent weeks, with five home runs and a .318/.348/.505 slash line in his last 112 PA.

With Castellanos now sidelined, Matt Vierling figures to see much of the action in right field. Bryce Harper is still limited to DH duty and isn’t an option in the outfield, leaving Vierling, utilityman Nick Maton and now Guthrie as the choices for right field playing time.

Guthrie was a sixth-round pick for the Phillies in the 2017 draft, and the 26-year-old is now on the verge of his major league debut. He posted some middling numbers over his first three pro seasons, but hit well enough in 2021 to earn a promotion from Double-A to Triple-A. Guthrie has continued to perform at the highest minor league level. Over 513 total PA at Triple-A in 2021 and 2022, Guthrie has hit .299/.354/.466 with 12 home runs and 23 steals (out of 30 attempts).
