The Washington Nationals visit Kauffman Stadium on Tuesday night looking to turn around a disappointing season against a Kansas City Royals team that's fallen short of playoff expectations after last year's surprise run.
Washington's Mitchell Parker faces a tough test on the road where he's struggled with a 6.10 ERA, while the Royals counter with veteran Michael Wacha, who's been dominant at home with a 2.63 ERA at Kauffman Stadium this season.
With both teams sitting below .500 and fighting to salvage their campaigns, this interleague clash could provide valuable momentum for whichever side can capitalize on their opponent's weaknesses.

Kansas City Royals vs. Washington Nationals preview
The Nationals and Royals kick off their first series of the season with both clubs fighting different battles - Washington sitting 23 games under .500 while Kansas City hovers around the break-even mark at 58-60.
Mitchell Parker takes the ball for the Nationals but has been particularly vulnerable away from home, posting a 6.10 ERA in 10 road starts compared to his overall 5.43 mark.
Michael Wacha counters for Kansas City and has been nearly untouchable at Kauffman Stadium this season, sporting a sub-2.00 ERA at home while the veteran right-hander has found another gear since the All-Star break.
The offensive numbers tell a stark story - Kansas City ranks dead last in MLB scoring at just 3.68 runs per game, while Washington manages a modest 4.3 runs despite their poor record.
Both teams enter this series coming off disappointing weekends, with the Nationals taking two of three from San Francisco but the Royals dropping two of three to Minnesota at home.
With Kansas City's pitcher-friendly ballpark and both starters capable of limiting damage, this opener has all the makings of a low-scoring affair between two clubs still searching for consistency.
