MLB Tuesday 10* Top Play OVER 9.5 in Washington Nationals vs Arizona Diamondbacks @ 7:05 ET - The Nationals are expected to start Jake Irvin here. Once he got about the single-A level in the minors he has struggled. He went 0-4 with a 4.79 ERA at the AA level last year. Then this season at AAA he was 2-2 with a 5.64 ERA. Unsurprisingly given those numbers, Irvin has also struggled at the MLB level since being called up. He is now 1-3 with a 5.67 ERA in his rookie year at the MLB level and Irvin has allowed 16 earned runs in 16 and 1/3 innings spanning his last 4 starts. The Diamondbacks starter is also a concern here for Arizona. Tommy Henry is expected to get the call and he has a 5.74 ERA in his 3 road starts this season. Last season, his rookie year, Henry had an overall 5.36 ERA and I am looking for the Nationals to hit him well here at home. Washington is decent at home where they have split their last 8 games and scored an average of 5 runs in their last 9 games. The Diamondbacks have been one of the better teams in the league this season in terms of hitting on the road as their .424 slugging percentage away from home ranks them 8th in the league. Also, Arizona is averaging 5 runs per game on the road this season. I would not be surprised to see each team get to at least 5 runs in this one and that would of course mean double digits in runs here. 10* OVER 9.5 in Washington
