Arizona Diamondbacks

About the Arizona Diamondbacks

The Arizona Diamondbacks are a Major League Baseball franchise based in Arizona, competing in the National League West. They share the division with four rivals and play a 162-game regular season from late March through early October, with the top finisher in each division and the three best remaining records in the National League advancing to the postseason via the Wild Card.

Home games are played at Chase Field, where the five-year rolling park factor sits at 1.05 — a hitter-friendly environment where runs come easier than league average. Expect elevated offensive output, more home runs, and higher totals in over/under markets when this team plays at home. Our win-probability and over/under models apply this factor directly when the ARI host a series, which is why home and away projections for the same two clubs can look noticeably different.
