Chicago Cubs vs Arizona Diamondbacks — 三月 18, 2026 | AI Prediction & Stats

Expect an evenly contested opener, but the Cubs’ deeper staff should tilt the balance. Chicago hands the ball to Kyle Hendricks, whose command-heavy approach matches up well with a free-swinging Arizona lineup that finished 22nd in walk rate last season. Hendricks’ soft-contact profile plays in the spacious gaps of Chase Field, and with high-leverage arms Julian Merryweather and Adbert Alzolay rested, manager Craig Counsell can shorten the game once he gets five to six frames. Arizona counters with Merrill Kelly, reliable but prone to early pitch-count creep. The Cubs have tagged him for a .292 average the past two seasons, and three of the first five hitters—Nico Hoerner, Ian Happ, and Dansby Swanson—own strong career numbers against his cutter. Chicago jumps out with a two-spot in the second on a Seiya Suzuki replacement combo: Alexander Canario doubles, Mike Tauchman walks, and rookie Owen Caissie plates both with a gapper. The Diamondbacks answer in the third via Corbin Carroll’s speed manufacturing a run, but the pivotal sequence comes in the sixth. With Arizona trailing 3-1, Christian Walker unloads on a hanging changeup for a two-run blast, tying the game and knocking Hendricks out. Counsell responds with Merryweather, who strands the go-ahead runner. Chicago’s bench depth shows in the seventh when Patrick Wisdom, pinch-hitting against lefty Joe Mantiply, launches a go-ahead solo shot. In the ninth, Hoerner’s RBI single off Paul Sewald provides insurance. The Cubs withstand a late eighth-inning Carroll RBI knock thanks to Alzolay’s cutter/slider mix. Key factors: 1. Suzuki’s absence hurts, but the Cubs’ run-prevention unit (second-best NL bullpen ERA last year) remains intact. 2. Arizona’s recent 1-4 slide highlights lineup volatility; they’ve scored three runs or fewer in four of those games. 3. Chicago’s 5–2 head-to-head edge over the last two seasons continues as the Cubs squeak out a one-run victory.
