Mariners vs Cubs

Windy City rumors say Castillo’s gem could shock the bleachers

Seattle Mariners

Mariners (37-36) VS Cubs (45-29)

Jun 21, 2025 | 2:20 PM ET | Wrigley Field, Chicago

Chicago Cubs
Moneyline Pick - Seattle Mariners (+143): B-

Seattle enters Wrigley Field winning three of their last five, and with Chicago streaking but missing its top arm due to injury, the pitching advantage shifts to the Mariners. Seattle’s starter has shown excellent velocity and command lately, which could prove critical against a Cubs lineup that has relied on timely power. The Mariners’ offence also benefits from favourable matchups, especially considering their recent success at this venue. While Chicago holds the better record, their current momentum may not fully offset the downgrade on the mound.

As creep closer to the halfway point, urgency weighs more heavily on Seattle, which needs every edge to stay alive in the AL Wild Card race. Their bullpen has performed well of late, limiting damage over the past several appearances and showing poise against high-leverage bats. The Cubs still pose a threat offensively, but with the odds offering plus money and the visitors showing a sharper edge in starting pitching, the road upset has tangible upside.

Over/Under Pick - Under 12 Runs, (-110): B+

Seattle enters Wrigley Field on a decent run slide while Chicago looks to end a two-game skid, but the real headline is the pitching duel between two frontline arms. The Mariners send out a reliable young arm, that has put up pretty good numbers away from home, while the home side counters with a right-hander who has been particularly effective at Wrigley this season. Both lineups are slightly depleted due to injuries, softening the offensive ceiling on either side just as they hit the midpoint of their schedules with playoff tiebreakers already in mind.

While individual bats have shown flashes in this matchup before, the forecasted wind blowing in at Wrigley should severely suppress power potential. That factor, paired with two quality starters and likely aggressive bullpen use from both managers, points squarely toward a low-scoring game. Even with the total sitting high at 12, the conditions and pitching setup make the Under a strong play.

Spread Pick - Seattle Mariners, +1.5 (-130): B

Seattle comes into Wrigley with late-inning confidence thanks to a bullpen anchored by a reliever who has assisted in the team's good run recently, while the Cubs are stuck in a two-game skid and still missing a key contact bat. Even with some minor health concerns in the Mariners’ lineup, key hitters have historically fared well against Chicago’s starter, offering enough production to keep this one close. The Cubs’ own middle-order threats face a tougher assignment, with their numbers against Seattle’s starter suggesting limited impact.

With both teams approaching the halfway point of the season, motivation swings more toward the Wild Card-hunting Mariners, while the Cubs focus more on long-term positioning. Chicago’s recent stretch of extra-inning games has also taxed its bullpen, giving the fresher arms from Seattle a potential edge late. Backing the visitors at +1.5 allows for a tight margin while offering a strong safety net against a narrow outcome.
