Nationals vs Rockies Pick, Betting Analysis

You’re telling me the hard-hitting Nationals are playing at Coors Field against Michael Lorenzen (6.22 ERA, 5.56 xERA, 87 Stuff+) in 90-degree weather with double-digit winds blowing out toward left field?

They might put up 15 runs in this alone.

However, Miles Mikolas is one of Washington’s worst starting pitchers (5.53 ERA, 4.99 xERA, 90 Stuff+), and Colorado’s offense is nothing to scoff at — Zerillo projects the Rockies with a 111 wRC+ against right-handed pitching behind the hard-hitting Hunter Goodman and six other above-average hitters.

Even better, Zerillo power rates these bullpens as the two worst in MLB.

I’m ready for fireworks in this matchup.

Pick: Over 13.5 (+100 or Better)
