Blue Jays at Mariners picks and predictions
Prediction
Blue Jays 6, Mariners 5
Moneyline
Toronto should avoid the sweep vs. the inconsistent Mariners. While Manoah is having the worst season of his career, he has been decent at bouncing back after bad performances. Manoah has allowed an average of just 1.00 ER in 5 games this season after giving up 4 or more ER in his previous start.
BET BLUE JAYS (+120).
Run line/Against the spread
Toronto +1.5 (-165) should hit, but there’s no need to pay the higher price on the run line when the Blue Jays should win straight up.
PASS. Bet the moneyline and/or the total instead.

Over/Under
Eight of Manoah’s last 9 starts have finished with 9 or more total runs. Woo has also been a worse pitcher at home this season and should help the Over hit for the 5th time in 7 games for the Mariners.
BET OVER 8.5 (-115).
