Harper wears Ledecky swim cap during Nats' celebration

Bryce Harper wasn't about to mess up his hair - no matter what the achievement.

As the Washington Nationals celebrated their third division title in five seasons Saturday night in the clubhouse, Harper donned a Katie Ledecky swim cap and goggles.

Ledecky, who won four gold medals and one silver at the Rio Olympics, met Harper earlier this season. The reigning NL MVP held her medals while she tossed the first pitch at Nationals Park.
