KEY PLAYER MATCHUPS
1. Bryan Reynolds vs. Slade Cecconi
Reynolds’ switch‑hitting power and ability to handle sliders make him the most dangerous bat in this matchup.
2. Christian Walker vs. Mitch Keller
If Walker is healthy enough to swing freely, he’s Arizona’s best chance to generate power vs. Keller’s cutter/fastball mix.
3. Jack Suwinski vs. Arizona bullpen
Suwinski’s late‑inning power is a major factor against a Diamondbacks bullpen with a 5.00+ ERA over the last two weeks.
