Mariners at Blue Jays picks and predictions

Prediction

Blue Jays 4, Mariners 3

Moneyline

Dating back to last season, Toronto is 6-2 across its last 8 games vs. Seattle.

The rest for Gausman -- pitching on 7 days' rest -- does not seem ideal. But the veteran righty, who posted a 2.81 ERA, 0.94 WHIP in the second half, clocked a 2.55 ERA when starting on 6-plus days in the regular season. And per ESPN, Gausman has held current Seattle batters to an aggregate .688 OPS.Miller, who is making just his second career playoff start, registered a 5.62 ERA after the All-Star break. He started against Toronto on May 11 and coughed up 7 runs in 5 IP.

The Mariners figure to have an edge in the bullpen matchup, but their relief corps starts this series a couple days in the hole in the rest department. And in road games east of the Mississippi, Seattle is 4-12 over its last 16 games.

FanDuel offers a BLUE JAYS (-166) line, and that's the best way to leverage this side.

Run line/Against the spread

Both sides tend to play a lot of 1-run games. Not looking to get Toronto by with a cushion. No interest; PASS.

Over/Under

The last 15 Seattle-at-Toronto games have seen the Under go 10-5.Some potential Toronto rust mixes with likely Seattle fatigue and makes a low score likely in this key first game of the series. Look for the game to be managed with a high-leverage tilt, as both clubs look to gain an early foothold.

TAKE THE UNDER 8 (-120).
