Nationals at Mariners picks and predictions

Prediction

Mariners 5, Nationals 3

Money line

The Mariners are hitting the ball with authority and have scored 5.8 runs per game in the last 10. Couple that with their ace righting the ship after a rough patch, and who has struck out 27 batters in 19 1/3 IP the last 3 starts, and this shouldn’t be close. Let’s go with MARINERS OVER 4.5 TOTAL RUNS (+100).

Run line/Against the spread

The M’s won the previous matchups 6-4 and 2-1. But they’re tattooing the ball, and the Nats are treading water offensively with 3.2 runs per game over the last 10. The MARINERS -1.5 (-117) should be more expensive and likely will be before 1st pitch.

Over/Under

The Over is going to depend on Washington’s ability to plate 3 runs. Ray has spotted the other team at least 1 ER in 8 straight starts. The Over is 4-0-2 in Ray’s last 6 starts. It will be close, but a slight LEAN OVER 7.5 (+105) is in order.
