Toronto Blue Jays vs Seattle Mariners: Mariners Moneyline

The Blue Jays’ offense continues to struggle to produce many runs despite having a solid lineup, averaging just 3.53 runs scored per game, while their pitching hasn’t been consistent either with an ERA of 4.39. For their part, the Mariners, leaders of the AL West, have a good collective ERA of 3.75 and boast the fifth-best offense in MLB, averaging 5.14 runs scored. The Mariners will have Luis Castillo on the mound, who has allowed only 1 run in his last 12.0 innings of work, and has an ERA of 3.29. Considering Toronto’s offensive woes, and that the Mariners are playing great right now, we expect the home team to take the win.

Injuries for Toronto Blue Jays:

Toronto Blue Jays vs Seattle Mariners: Under 7.5

The Blue Jays’ offense has been a disaster this season, so we think Castillo shouldn’t have many complications stopping them and recording another good start here. However, although the Mariners usually produce a lot of runs, here they will face a Kevin Gausman who recovered from a couple of bad outings with 6.0 innings and only 1 hit allowed against the Guardians. This will be an entertaining pitching duel, so we expect a low-scoring game.
