The Phillies staged one of the most memorable comebacks of the season Thursday, rallying from a 5-1 ninth-inning deficit against the Cubs to pull off a 7-5 victory. The game ended on a walk-off grand slam from outfielder Bryce Harper, with first baseman Rhys Hoskins among the players he knocked in. Hoskins got on base after taking a Pedro Strop pitch off the right hand, and it’s possible he suffered an injury in the process. The slugger underwent an X-ray on his hand afterward, Jim Salisbury of NBC Sports Philadelphia was among those to report. Hoskins is optimistic he’ll be OK, but there’s no official word on his status yet.

Although Thursday was a resounding success for the Phillies, losing Hoskins would dampen enthusiasm in regards to their outlook. The club’s Harper-led triumph Thursday completed a three-game sweep of Chicago and raised Philadelphia’s record to 63-55. The Phillies are now just a game back of the Cubs for the National League’s second wild-card spot. Although Hoskins has been cold in August, the 26-year-old has still been one of the driving forces behind the Phillies’ solid record. Hoskins has batted .241/.381/.485 (125 wRC+) with 24 home runs and 2.4 fWAR across 532 plate appearances.

Along with posting quality production, Hoskins has been among the Phillies’ most durable players. To this point in the season, only two of the team’s other players – catcher J.T. Realmuto and third baseman Maikel Franco – have started games at first, and they’ve each done so just once. It’s unclear which Phillie would receive the bulk of the work at first in the event of a Hoskins injured list stint, but just-promoted veteran Logan Morrison seems like a strong bet.
