With a likely season-ending injury to Ryan Howard, the Phillies regular 1st baseman for more than a decade, the club has apparently decided to give an increased opportunity for playing time to Darin Ruf, who has spent much of this season and his career shuffling between 1st base, left field, and the bench.
In this 2015 season, the Phillies have given 602 plate appearances to those two players, Howard (466) and Ruf (136), at the 1st base position. The pair have combined for 27 home runs and 91 RBI. Those are not bad numbers for the power and run-production totals that teams expect out of that position in the lineup.
