Pete Alonso repeats as Home Run Derby champion A re-Pete, for the Home Run Derby. Posted: Jul 12, 2021 10:08 PM Posted By: Associated Press Pete Alonso of the New York Mets became the third back-to-back Home Run Derby champion, beating No. 6 seed Trey Mancini in the final. Alonso and his blue-and-orange bat went 6 for 6 in a 28-second stretch to give him 23 homers in the final round after Mancini hit 22 in the thin Rocky Mountain air. The 26-year-old Alonso joins Hall of Famer Ken Griffey Jr. (1998-99) and Yoenis Céspedes (2013-14) as the only players to win two straight. Alonso has one distinction, though - his titles are over three seasons. There wasn’t an event last season due to the coronavirus pandemic.
