San Diego Padres vs. Washington Nationals

Quick read:

Expecting the over 9.0 in the Padres vs. Nationals game is a straightforward call given how both teams have been performing offensively and defensively. Neither side is exactly a fortress—San Diego's run differential is a hair positive, while Washington's leans slightly negative, suggesting plenty of scoring opportunities.
The Padres have managed 221 runs and allowed nearly as many, while the Nationals have given up more runs than they've scored. Combine that with their respective hit totals—399 for the Padres and a hefty 491 for the Nationals—and you're looking at lineups capable of making the pitching staff sweat.
The only real risk here is if the pitchers suddenly develop pinpoint control or the weather decides to turn the ball into a slugfest killer. But hey, if you're banking on that, you might want to rethink your day job.
