If you missed a recent piece I did on pitchers who excel in the second-half of seasons, I highlighted Tanner Roark as one to keep your eye on. The Nationals right-hander has always pitched much better after the All-Star Break and has done so once again this season.

Roark, who has a career second-half ERA that sits over a run lower than his first-half ERA, has been absolutely dominant in three starts since the break this year. He has a 3-0 record with a sparkling 0.82 ERA in those games. The former Illinois product went at least seven innings in each. I expect a strong outing from a confident Roark, who may have a little extra pep in his step pitching in his home state. (Roark is 3-1 with a 3.24 ERA in three career starts at Wrigley Field.) He can also help himself a little at the plate.

On the complete other end of the spectrum, Jon Lester has been an absolute mess since the All-Star Break. The Cubs lefty is 0-2 in four second-half starts with a staggering 8.53 ERA. After benefiting from good fortune for most of the first half, he’s on a regression ride that is far from over. Look no further than his 4.83 FIP (a more accurate measure of performance) — over a full run higher than his 3.44 ERA. I think a healthy Nationals lineup can take advantage of a reeling Lester. On the surface the Cubs are sending out a 12-4 starter vs. one that is 6-12, but it’s the latter you should trust.

With Kelvin Herrera and Seth Doolittle on the Disabled List, the Nationals bullpen is a mess right now so I will be splitting this bet between the full game and first five innings.

The Bet: Nationals First-Five +108 (1/2 unit) and Nationals +115 (1/2 unit)
