Washington Nationals outfielder Bryce Harper is playing in the National League Division Series while dealing with strep throat, the Washington Post's James Wagner is reporting. Harper, who went 0-for-5 in Monday's 12-4 loss to the St. Louis Cardinals in Game 2, is taking antibiotics as he battles a fever and sore throat.

Harper's illness is not expected to keep him out of the Nats' lineup for Game 3 as the medicine is helping, says the 19-year-old. Tuesday's off day may also help improve Harper's health.

So far in his first postseason series, Harper has struggled, collecting just one hit in 10 at-bats. The left-handed hitter has no RBI, runs or extra-base hits.

On Wednesday, Harper will face St. Louis' right-handed pitcher Chris Carpenter. During the season, Harper hit 16 of his 22 home runs with a .280 batting average against righties.

Game 3 of the NLDS is schedule to start at 1 p.m. ET and will be broadcasted on MLB Network.
