Stephen Nover's MLB August Total of the Month
(MLB) Washington vs. Miami,
Total: 7.50 | -102.00 Over
Result: Win
I see this total as being at least one run too low. 

The Nationals average 4.5 runs on the road. They are averaging 5.7 runs during their last eight games.

The Marlins average more than four runs per game at home. 

The pitching matchup is lefty Patrick Corbin versus righty Elieser Hernandez. 

Corbin has mostly been terrible this year. He's 7-12 with a 5.82 ERA. He's given up four or more earned runs in four of his past seven starts. 
Hernandez, who has a 4.15 ERA, will be making just his fifth appearance of the season. He last started six days ago against the Reds and was tagged for five runs, four of which were earned, in 4 2/3 innings. Hernandez gave up two homers during that game. 

The Nationals have the second-highest batting average against righthanders in the National League. 

Note, too, that Joe West is slated to be the home plate umpire. The Over has won 59 percent of the time West has been behind the plate the past two years spanning 34 games.
