Padres Rout D-backs 9-4 to Clinch Home Field

The San Diego Padres closed the 2026 regular season with a 9-4 win over the Arizona Diamondbacks at Petco Park on Sunday, locking up home-field advantage for the Wild Card round and ending Arizona's postseason push on the final day. The story of the game was simple: San Diego's offense delivered, and the pitching gap we flagged before first pitch showed up in full.

How the premium pick graded out

Our moneyline call on Arizona went down as a loss. The D-backs needed a win and help, and instead they fell by five — the sharpest side of the board was the right side, just not the one our model leaned toward.

Our run line on San Diego +1.5 was a comfortable winner, and the over also cashed as the two teams combined for 13 runs.

Prop card results

• Geraldo Perdomo over 0.5 walks (+118): WIN. One walk on the day, and at plus money that single non-competitive at-bat paid exactly as scripted.

Takeaway for future picks

The bigger lesson sits with the starting pitchers. Randy Vásquez, whose surface numbers looked ordinary, turned in six innings of one-run ball with two strikeouts and no walks. Michael Soroka gave Arizona 4.2 innings with three earned runs allowed. The gap between the two arms played out on the scoreboard, and it reinforces the value of trusting the underlying arsenal over the headline ERA when the two disagree — a principle worth carrying into the postseason card.
