The wild card for Blue Jays bettors is that Toronto is relying on two lefthanders who have never pitched in Seattle before, but they will start a road series with a pitcher who has delivered value on the road of late. The Blue Jays are -173 away favorites and the Seattle Mariners are +148 home underdogs with a 8.5-run total on the <a href="https://www.oddsshark.com/mlb/odds?utm_source=BlueJaysNation&amp;utm_medium=referral&amp;utm_campaign=TNN&amp;utm_term=editorial&amp;utm_content=BlueJays">MLB odds</a> for Friday at sportsbooks monitored by OddsShark.com (<a href="https://www.oddsshark.com/sports-betting/betting-money-line?utm_source=BlueJaysNation&amp;utm_medium=referral&amp;utm_campaign=TNN&amp;utm_term=editorial&amp;utm_content=BlueJays">how the moneyline works</a>).

The Blue Jays&#8217; 62-52 record includes a 17-9 mark since the all-star break. Their offense is third in run scoring (5.18 per game) and first in OPS (.786).

Toronto is eighth in starting pitcher ERA (3.74) and 12th in reliever ERA (3.96). The Blue Jays, overall, have the fourth-best ERA (3.29) since the all-star break.
The Mariners are 61-55, but just 13-12 since the all-star break. Their offense is 22nd in run scoring (4.16 per game) and 28th in OPS (.680). Kyle Seager (.880 OPS since July 16), Ty France (.872) and Mitch Haniger (.822) have been Seattle&#8217;s leading hitters over the last four weeks.

Toronto is 5-1 in its last six games when it was an away favorite with Ray starting, and the last four such matchups have finished UNDER. Ray has a 3.91 ERA in 23 career innings against Seattle.
