MINNEAPOLIS -- Yoenis Cespedes of the A's became the first back-to-back winner of the Home Run Derby in more than a decade, beating the Reds' Todd Frazier with an impressive final round that included several shots delivered to the second and third decks of Target Field, areas that seldom see baseballs.

Cespedes hit nine homers in the final round to Frazier's one. He beat Washington's Bryce Harper, 9-8, in the 2013 final. The last back-to-back winner was the Mariners' Ken Griffey Jr., who won in 1998 and 1999.

In the semifinal round, Cespedes beat the Blue Jays' Jose Bautista, 7-4, and Frazier beat the Marlins' Giancarlo Stanton, 1-0.

Stanton might have tired himself out in the first round when he swatted six homers, including one that landed halfway up the third deck and was estimated at 503 feet. Bautista hit 10 homers in the first round, the most any participant hit in any round in the competition.

Cespedes entered the break with 14 homers for the AL-West leading A's.
