What's at stake

A single regular-season game determines which team wins the moneyline and where multiple totals and run-line bets will settle.

Payouts hinge on the final score margin and combined runs; totals from 9.5 to 15.5 and Rockies run-line prices up to -5.5 will resolve based on official scoring.

Who's in play

Atlanta's starting pitcher and bullpen usage matter most, as does Colorado's lineup strength at Coors Field.

Managers Brian Snitker and Bud Black, catcher pitch-calling, and late-inning relievers determine substitutions and score margin.

What drives it

Starting pitchers' handedness, pitch counts, and expected innings drive run totals and the run-line.

Altitude and weather at Coors Field, bullpen health, lineup left/right splits, and in-game managerial pitching decisions change probabilities during the contest.

What to watch

Probable starting pitchers and official lineups, announced about an hour before first pitch, set initial expectations for totals and run-lines.

Monitor weather updates, game-time wind, bullpen warmups, and late scratches; mid-game pitching changes and extra-inning scoring will decide over/under and run-margin outcomes.
