The set-up: The Cardinals went 3-8 from June 13 through June 24, clinching the team's first sub-.500 month since June of 2016! However, the Cards beat the Pirates 8-4 on June 25 and capped a 5-1 run to end June with last night's 8-1 home win over the Nationals. Yes, St. Louis ended June 13-16 but three of the team's five victories have come over 50-31 Arizona and 47-33 Washington. A big reason for the team's recent surge is a pitching staff which has allowed four or fewer runs in each of the wins and allowed just one run on six hits Friday to the Nationals, who lead the NL in runs scored (3.39 per). The Nats have injury issues at the top of its lineup with Trea Turner (fractured wrist) Aand dam Eaton (knee) on the disabled list. However, the Nats still own an 8 1/2 game lead in the NL East.

The pitching matchup: Gio Gonzalez (7-2 & 2.87 ERA) takes the mound for the Nats and Michael Wacha (4-3 & 4.50 ERA) for the Cards. Gonzalez is having a very solid season, as he has allowed three or fewer runs in 14 of his 16 starts, including each of the last seven. Gonzalez faced St. Louis back on April 11 and allowed two runs (one earned) on six hits without walking a batter in seven innings to earn an 8-3 win. Wacha has not had much consistency in 2017 but bounced back from two sub-par outings with an 8-2 win over Cincinnati on Monday, scattering one run on five hits over six innings. However, he did not record an out in the fifth inning in either of his two previous starts, surrendering a total of nine runs (six earned) on 16 hits in eight innings (6.75 ERA). That said, Wacha is 2-2 with a 1.57 ERA in four career starts against Washington

Gonzalez owns a splendid 2.87 ERA but yet, Washington is only 9-7 in his 16 starts this season. In keeping with that, although he owns a 2.86 career ERA against the Cards, his teams are just 5-4 in nine starts. Throw in Wacha's 1.57 ERA in four starts against the Nats and it's a 10* on the Under.
