Who will win Cubs vs Mariners today: Cubs moneyline (-116)
Talk about a discount on the Chicago Cubs to secure a win this afternoon against a right-hander who sports an 8.04 ERA and 1.60 WHIP while allowing an 11.5% barrel rate over his last three outings.
On top of that, they draw a lineup that owns a 25% strikeout rate, .676 OPS, 4.3% barrel rate, and 98 wRC+ over its last six games.
Meanwhile, the Seattle Mariners draw Shota Imanaga, who has been shoving over his last five starts, maintaining a 3.18 ERA and 0.99 WHIP while limiting opponents to a 31% hard-hit rate. Chicago's bats, on the other hand, have been on fire over their last six games, posting a 119 wRC+, .348 wOBA, and .799 OPS.
With how bad Bryce Miller and the Mariners' bats have been, getting the Cubs at $1.16 is a steal.
COVERS INTEL: Alex Bregman sports a .333 BA, .704 SLG, 1.104 OPS, and .371 ISO over his last 30 plate appearances against right-handed pitchers. Cubs vs Mariners Over/Under pick: Over 7.5 (-103)
Despite Imanaga pitching at a very high level across his last five starts, there are some concerning underlying metrics. Over his last three starts, opposing hitters have generated nearly a 17% barrel rate against the Cubs southpaw. On top of that, Miller has allowed over an 11.5% barrel rate to opposing hitters. Both pitchers could be in for a rough start.
On top of that, even though the Mariners’ bats have been ice cold, they have been drawing a ton of walks, which could help get ducks on the pond and drive in some runs.
The Cubs will expectedly be the main contributors to taking this thing over, but expect the Mariners to help out a bit, too, with Imanaga’s recent flaws.
