San Francisco Giants lefty Madison Bumgarner could present a bit of a challenge for the hot hitting Washington Nationals on Wednesday morning. As a result, the Nationals are using a different lineup to take on the 22-year-old pitcher.

After hitting in the bottom of the order in Tuesday's win, second baseman Danny Espinosa, a righty, is in the leadoff spot. He has a .947 OPS against southpaws. Ian Desmond, who went yard in Tuesday's game, replaces Adam LaRoche in the fifth spot in the order.

The complete lineup looks like this:

#Nationals lineup 7/4 vs. #Giants - Espinosa 4, Harper 8, Zimmerman 5, Morse 7, Desmond 6, Moore 3, DeRosa 9, Solano 2, Jackson 1

A win would extend Washington's NL-leading record and preserve their lead on top of the NL East with the All-Star break looming.
