The Seattle Mariners and Toronto Blue Jays meet Wednesday in MLB action at Sahlen Field. The Mariners look for a win after splitting their last six games. The Blue Jays look for a win after winning eight of their last nine games.

The Seattle Mariners have scored 11 runs in their last three games and four or more runs in five of their last nine games. The Mariners have won eight of their last nine games when scoring four or more runs. JP Crawford leads the Mariners with 80 hits and 30 RBI while Mitch Haniger and Ty France have combined for 143 hits and 77 RBI. Justus Sheffield gets the ball, and he is 5-7 with a 5.69 ERA and 54 strikeouts this season. This will be Sheffield’s second career game against the Blue Jays.


The Toronto Blue Jays have scored 26 runs in their last three games and four or more runs in five straight games. The Blue Jays have won eight of their last 11 games when scoring four or more runs. Vladimir Guerrero Jr. leads the Blue Jays with 96 hits and 66 RBI while Marcus Semien and Bo Bichette have combined for 180 hits and 103 RBI. Steven Matz gets the ball, and he is 7-3 with a 4.26 ERA and 75 strikeouts this season. This will be Matz’s first career game against the Mariners. 

The Mariners are 1-8 in their last 9 Wednesday games and 7-2 in their last 9 overall. The Blue Jays are 5-2 in their last 7 Wednesday games and 7-1 in their last 8 overall. The over is 4-1 in Mariners last 5 road games. The under is 4-1-1 in Blue Jays last 6 overall. The Mariners are 4-1 in the last 5 meetings.

The Blue Jays should be favored and should win, but the price is a bit steep. I’m looking at the over instead. Matz has allowed four or more earned runs in four of his last nine starts. Sheffield has allowed 16 earned runs in his last 19 innings. Expect to see some fireworks in this one. Give me the over the total.
