Astros at Mariners picks and predictions

Prediction

Astros 5, Mariners 3

Moneyline

This is a pretty even matchup between 2 very good pitchers. But it’s worth noting that McCullers excelled down the stretch with 5 ER allowed and a 24/7 K/BB in 19 IP while Kirby struggled over his final few starts. Look for the ASTROS -115 to complete the sweep.

Run line/Against the spread

Of Houston’s last 12 road wins, 10 of them have been by more than a single run. Though Kirby has been strong throughout most of the year, he hasn’t pitched well his last few times out and will be put to the test against one of the league’s top offenses. We’ll side with the ASTROS -1.5 (+150).

Over/Under

We have discussed the recent issues for Kirby, and McCullers hasn’t been quite as good as his ERA would suggest. Both his FIP and xFIP are more than a run higher than his 2.27 ERA.

Both of these offenses are top 10 in wRC+ vs RHP, and while neither is a good bet to explode for a huge day, neither is likely to be completely shut down, either. Back the OVER 6.5 (-125).
