By stepping onto the field, Bryce Harper will make history. He is the first Nationals player to compete in the Home Run Derby. His father, Ron, will throw to him. He will be the sixth hitter to compete, after Chris Davis and before Robinson Cano. Prince Fielder is the defending champion. We’ll provide updates here as they happen. Feel free to comment below.

The first round order: Prince Fielder, Michael Cuddyer, Yoenis Cespedes, Pedro Alvarez, Chris Davis, Bryce Harper, Robinson Cano, David Wright.

FINAL ROUND UPDATE, 10:53 p.m.: Yoenis Cespedes win the Home Run Derby with a titanic shot to center, his ninth, and flips his bat. Bryce Harper finishes second with eight.

FINAL ROUND UPDATE, 10:41 p.m.: Bryce Harper hit eight home runs in the final round. He and his father shared a long embrace, both sweaty from the hot, humid New York night. Yoenis Cespedes needs nine home runs to win. If not, Harper would be the youngest derby winner.

ROUND 2 UPDATE, 10:16 p.m.: Bryce Harper hit eight home runs in the second round, knocking out Michael Cuddyer, and advances to the final against Yoenis Cespedes. At one point, he hit five straight homers, many of them line drives out of the stadium. He hugged his father again. Cespedes will still hit in the second round, even though his 17 first-round homers are still tops.

ROUND 1 UPDATE, 10:07 p.m.: Bryce Harper has a chance to advance to the second round if he hits right home runs, as first-round scores carry over.

ROUND 1 UPDATE, 9:39 p.m.: Yoenis Cespedes (17 homers), Chris Davis (8), Bryce Harper (8) and Michael Cuddyer (7) advance.

ROUND 1 UPDATE, 9:31 p.m.:Harper will advance to the second round regardless of what David Wright does. Robinson Cano hit only four home runs, so, at least, Yoenis Cespedes, Chris Davis and Bryce Harper will advance.

ROUND 1 UPDATE, 9:20 p.m.: Harper hit eight home runs in the first round, including a 471-foot missile to right-center field, one of the longest of the entire round. He averaged 415 feet on his homers, the most among the hitter so far. He’s tied with Chris Davis for second, likely in a good spot to advance to the second round. Yoenis Cespedes put on an absurd show of power with 17 home runs, many to the third deck in left field. Two home hitters are left: David Wright and Robinson Cano.
