Arizona Diamondbacks vs. Washington National

Quick read:

Backing the over 9.5 total runs is a straightforward play when Arizona’s offense can both score and concede at almost the same rate. Their 469 runs scored paired with 467 allowed implies games frequently get messy, making a high-scoring affair more likely than not.
Arizona’s 839 hits this season underline their ability to consistently put the ball in play, which should translate into sustained innings and plenty of scoring chances. When a team averages that many hits, it’s tough to keep the scoreboard under 10 runs combined, especially against a National team that hasn’t been noted for lockdown pitching.
The only real wrinkle is if the Nationals suddenly find their pitching groove or the Diamondbacks decide to take a day off, which is always possible but not very probable considering the season-long trends. So, if you’re looking for a number that’s unlikely to be boring, this over 9.5 run total fits the bill.
