Cubs' 15-Game Wrigley Winning Streak Is a Betting Signal You Can't Ignore

The Cubs are 15-0 at Wrigley Field in their last 15 tries, capping the run Thursday with an 8-3 demolition of the Reds to complete a four-game sweep. As MLB.com reported, it's the longest home winning streak at Wrigley since an 18-game stretch in September 1935 — a 91-year-old mark now squarely in Chicago's crosshairs. The North Siders are 26-12 overall, 18-5 at home on the season, and 19-3 in their last 22 games. This isn't a hot streak anymore. It's a structure.

The engine Thursday was Shota Imanaga, who delivered six innings of one-run ball and punched out 10 Reds batters — his fifth quality start of 2025. His ERA now sits at 2.28, and the performance was vintage Imanaga at Wrigley: deep into the game, high strikeout rate, minimal baserunner traffic. The Reds didn't reach second base until the fifth inning. When a lefty is working that deep and that clean against a lineup, double-digit strikeout totals stop being a surprise and start being a baseline expectation.

The offense is broad and deep, which is the more dangerous signal for opposing pitchers. Michael Conforto — playing in his first start since April 29 — went 3-for-3 with a walk, a solo homer, and an RBI walk in a seven-run fourth inning. He's slashing .361 with a 1.134 OPS across just 36 at-bats this season in a bench role. Ian Happ extended his on-base streak to a career-high 28 games. Nico Hoerner, Pete Crow-Armstrong, Dansby Swanson, Moisés Ballesteros, and Miguel Amaya all contributed RBIs. Craig Counsell has legitimate lineup depth — this isn't a two-star team propped up by circumstance.

For team total bettors, the Cubs at Wrigley is one of the cleaner lean-over situations in the league right now. Chicago has scored 208 runs on the season — third in baseball behind the Braves and Yankees — and the home environment is clearly a genuine performance amplifier. Imanaga's next Wrigley start deserves heavy attention on the strikeout prop: 10 Ks Thursday, a 2.28 ERA, and a demonstrable pattern of extended, high-volume outings at home. The over on his K line should open as a priority look. Meanwhile, any game where Conforto is in the starting lineup at Wrigley becomes a hits or total bases value, given that he's essentially operating like an elite hitter in a part-time role with elite underlying numbers.

The NRFI angle is worth monitoring too, but cuts the other direction — the Cubs have been the team scoring first consistently at home, which means fading the no-run-first-inning on Chicago home games carries real weight. When a lineup this productive faces a back-of-rotation or middle-of-the-road arm, the first-inning run probability climbs fast. Track the Cubs' first-inning run rate at Wrigley over the next two weeks. It will matter.
