Since Dave Roberts became manager Dodgers 17-5-1 O/U trying to end a three-game losing streak (13-0 O/U when they score 1+ off the opponent pen). Muncy, Gale, and Buehler have no data versus Wacha, while the other six Dodgers in the lineup own a combined .954 OPS against him in 65 combined at bats. This season Dodgers 5-0 SU 11±4 rpg lined less than -120 versus RHP.
The umpire leans heavily toward the Cards. Since Sep 14, 2017, the home team in the last game of the series has gone 10-0 SU with Miller behind home plate, and the Cards are 23-14 SU career overall with Miller behind home plate (sine 2004) - the most profitable MLB team in that spot behind Cleveland.
Cards 8-4 O/U this season and 7-0 O/U when their bullpen allows 1+ runs.
