The last two NL Cy Young winners meet Tuesday when the Cubs visit the Nationals. Reigning winner Jake Arrieta has struggled this season, as evidenced by his 4.36 ERA and pedestrian 7-5 record. But he is 1-0 with a 1.42 ERA in three career starts at Nationals Park. Washington ace Max Scherzer is 2-1 with a 3.19 ERA in five career starts against the Cubs. The current Cubs roster is hitting .234 against Scherzer, while the Nationals are batting .234 against Arrieta. Look for this to be a classic pitching duel that goes Under the total.
