As you know if you have paid attention to the Phillies at all this year, their pitching staff is quite terrible. They rank 28th as a staff in Fangraphs wins above replacement, better than only the 47-68 Mariners and 38-75 Orioles. Neither the bullpen nor rotation has been consistent at all this season.
While the pitching staff is terrible, the team certainly tried to improve it in recent years. Heading into last year, they signed starter Jake Arrieta and relievers Pat Neshek and Tommy Hunter. This offseason, they signed David Robertson and traded for James Pazos, Juan Nicasio, and Jose Alvarez.
