The Rockies have struck out almost 30% of the time against lefties this season, tops in the majors in that category. Jesus Luzardo is a high-K lefty. He's inconsistent, but has 18 strikeouts against zero walks in 13 1/3 innings in his last two starts. The Rockies are a bad offense on the road, which is a bonus, especially since they just left Coors Field (there's historically been an adjustment period).
