That would be playoff hero Walker Buehler, who closed out last year's World Series with the Dodgers, but hasn't closed much this season, other than "the book on a number of subpar outings". Buehler, who joined the Phillies organization before the Sept. 1 cutoff line, will be eligible for postseason play if the team deems him worthy of a roster spot. In order to make room for Buehler, the Phillies weakened their bullpen, placing José Alvarado on the Injured List, seemingly out of nowhere. A 40-man roster move was also necessary to bring Buehler to the bigs, so the Phillies DFA'd former Tigers top prospect Matt Manning. Phillies are putting José Alvarado on the IL to get Walker Buehler on active roster.
