Top Projected MLB DFS Pitchers

Tonight's slate features top-tier aces and several value arms flashing immense strikeout upside.

Jake Bennett (BOS): Bennett serves as an excellent low-owned tournament pivot. He does not allow many home runs and faces an Orioles lineup that boasts a 119 wRC+ but strikes out at a heavy 27% rate against left-handed pitching since the break.
 

WEATHER ALERT: The Marlins vs. Royals matchup features hot and humid conditions with winds blowing out, creating one of the best offensive environments in the league. The Red Sox vs. Orioles game carries definite postponement risk due to heavy forecasted rain.
