Chicago Cubs Team Overview
The Cubs have played two competitive games but have twice failed to hold onto their lead. On Saturday, they were up 4-2 heading into the ninth inning, but the relievers once again faltered down the stretch.

⚾ Starting Pitchers
Bryce Miller is slated to start for Seattle - he’s 4-7 with a 3.71 ERA. While his current official numbers are slightly less impressive than earlier CBS projections, Miller continues to limit walks and consistently delivers five to six competitive innings for the Mariners.
Shota Imanaga enters at 8-9 with a 3.77 ERA and 140 strikeouts. This is a closely matched pitching duel, offering the Cubs no clear advantage on the mound.
⭐ Editor's Pick
Imanaga has the tools to halt the hosts’ current momentum, so Game 3 of the series doesn’t look like a foregone conclusion despite back-to-back wins for Seattle. The Mariners have twice rallied past the Cubs in the late innings and are riding a run of five wins in their last seven games. Both starting pitchers are virtually even when it comes to ERA, but Chicago’s bullpen has squandered leads on consecutive nights. Home-field advantage and Seattle’s strong finishes tip the balance in favor of the Mariners. We’re backing a Seattle Mariners win.
