Bryce Harper gave Washington Nationals fans a deal on tickets by winning the Home Run Derby at Nationals Park on Monday night.

Prior to the event, the Nationals emailed their mailing list promising to reduce ticket prices of lower-level seats by $1 for every home run Harper hit, down to as low as $1.

Harper hit 45 home runs in the derby. With lower-level tickets in two sections starting at less than that amount, it means tickets for those seats to five games will sell for a dollar while supply lasts, as long as fans use one of the two discount codes sent out by the team.

Games eligible for the discount are contests against the New York Mets on July 31 and Aug. 1 and games against the Cincinnati Reds on Aug. 2, 4 and 5.
