Cardinals starting pitcher Lance Lynn is off to a promising start in 2015, posting a 1.64 ERA heading into his start Tuesday against the Nationals. If Lynn pitches like he did last season against the Nationals, then that ERA could continue to drop.

In two starts against Washington last year, the right-hander went 2-0 with a 0.66 ERA and 0.73 WHIP. He allowed just one run in 13 2/3 innings. He also had 13 strikeouts.

Lynn will be facing off against Nationals starting pitcher Gio Gonzalez. Baseball fans could be in for a pitcher's duel, as Gonzalez has a 1.17 ERA in three starts against the Cardinals since 2012.

The Nationals enter play Tuesday with 53 runs, which equals the league average.
