Arráez was injured trying to avoid a tag at first base against Milwaukee late last week. He did not return for the final regular-season series, though the club had hoped he could be ready for the postseason. MLB reported Monday that he still had not taken a swing since the injury. That made a short series difficult to manage: an unavailable position player would leave the Phillies with one less bench option for games that could decide their season by Thursday.
Philadelphia loses a central contact bat. Arráez hit .310 across the season and .278 after joining the Phillies from San Francisco at the trade deadline, according to PhillyVoice. He had been the club’s cleanup hitter, so Mattingly must decide both how to cover second base and who will hit in that part of the order. Bryson Stott has been playing second in Arráez’s absence, while Alec Bohm and Bryce Harper have also shifted defensive spots. Tuesday’s official lineup will establish the actual Game 1 arrangement.
