We have 2 pitchers each heading in opposite directions. In Tanner Roark's first 20 starts, he recorded three wins, 12 losses and five no-decisions. Over his last three outings, the Nats starter is 3-0 with a minuscule 0.82 ERA. On the flipside we have Cubs starter Jon Lester, who has racked up a 5.62 ERA in his last three starts and has really struggled since the All-Star Break. I like the Nationals bats here to get to Lester and get the win on Saturday afternoon.
