The O’s have opened this series with 2-0 and 4-1 victories the last 2 nights. 1B Ryan O’Hearn went 2-for-3 with his 11th HR and 3 RBIs to lead the charge Wednesday. Baltimore has won 2 in a row and 6 of its last 7 games.

Orioles at Mariners picks and predictions
Prediction
Orioles 4, Mariners 2
Moneyline
It’s rare that I personally drop -155 on a ML in baseball because the variance is so large. However, I’m fully on board with this one. Burnes is 5-1 a 2.11 ERA in his last 7 starts, and he owned the Mariners in his May outing. The M’s are a sinking ship that will need to add a couple of bats at the trade deadline.
Take the ORIOLES -155.
Run line/Against the spread
I know Burnes fanned 11 the last time he faced the M’s, but I’m going Under here. His 8.4 K/9 is the lowest since his 38-inning rookie season in 2018. He has struck out 11 twice this season, but he has been Under this number in each of his other 15 starts. Go with that trend and take CORBIN BURNES UNDER 7.5 K’S (-120).
Over/Under
The O’s are 5-5 O/U in their last 10, and the M’s are 4-4-2. The Over is 4-5-1 in the last 10 matchups. The Under has cashed on totals of 7 and 7.5 in the 1st 2 Games of the series. The wind is blowing in at 10 mph from left-center. Go easy here, but LEAN UNDER 7 (-110).
