Dempster, who has struggled against AL lineups in his career, has been better than expected. He has a 3.38 ERA, 1.125 WHIP and 33 strikeouts in 24.0 innings.
Nava vs. lefties
The switch-hitting Daniel Nava hasn’t hit southpaws well in his career with a .208 career average.
But he is 4 for 10 against lefties this year.
Red Sox hitting coach Greg Colbrunn and assistant hitting coach Victor Rodriguez have helped Nava adjust his mechanics from the right side of the plate.
“With that you just feel more comfortable and allows me to be more consistent,” Nava said.
