Even after his historic performance, Guerrero Jr. was tied by Pederson, who also hit 29 homers in the second round, initiating a tiebreaker to see who would advance to the championship round.
This year's field of eight hitters includes several rising stars, including New York Mets rookie first baseman Pete Alonso and Toronto Blue Jays rookie third baseman Vlad Guerrero Jr. "Oh my god, that was a blast", Alonso said after his win.
(It should be mentioned that both players in the final round, not just Alonso, had customized cleats).
Needing 23 homers to beat Guerrero, Alonso connected for a homer to left-center before flipping his bat high into the air and hugging his pitcher, cousin Derek Morgan.
Pete Alonso has been the lone shining star in a awful start to the first half of the season for the New York Mets and proved it when he won the Home Run Derby on Monday. "We gave everyone a good show, and that's what we wanted".
From his winnings, which almost double his 2019 Mets salary of $555,000, Alonso has pledged to donate 5 percent each to the Wounded Warrior Project and Tunnel to Towers foundation.
As Vladimir Guerrero Jr., put his impressive power on full display during Monday night's Home Run Derby, his Hall of Fame father was enjoying the show.
The 20-year-old Guerrero smashed out 29 home runs in the opening round of the Derby against Oakland's Matt Chapman - breaking the old record of 28 set by Josh Hamilton in 2008. "I'm going to remember that for the rest of my life", Alonso said.

Guerrero defeated Pederson in a semifinal that required three extra swing (ings) and will go down in derby lore. The contest moved to a three-swing format for each slugger as Guerrero hit a homer with one out of his three cuts.
Pederson opened the event with an impressive 21 homers to beat Houston's Alex Bregman (16).
"I'm happy I didn't face him in the early rounds because he would've knocked me out", Alonso said. Pederson also hit one homer, so the players were tied yet again. He got $500,000 for finishing second, plus a $100,000 bonus for hitting the longest homer.
