Much of the night belonged to Vlad Jr., but the 2019 Home Run Derby title (and million-dollar prize) belong to Pete Alonso as the Mets rookie edged the Blue Jays phenom in the final round of a thrilling derby in Cleveland.

What's the MLB commercial say? Let the kids play? Well, we have the kids in the finals of the Home Run Derby as rookies Vladimir Guerrero and Pete Alonso face off. On the line: $1 million -- or almost double their rookie salaries.

Ronald Acuna Jr. hit 19 home runs in the semifinals. Will Pete Alonso top that for a chance to face Vlad Jr. in the final?

Wow! What a show. Vlad Jr. somehow, someway finally outlasted Joc Pederson to reach the Home Run Derby final, where he'll face either Pete Alonso or Ronald Acuna Jr.

Are you serious!? After they tied with 29 home runs, Vlad Jr. belted 8 more in the tiebreaker round and Joc Pederson somehow matched him with a blast at the buzzer forcing a second tiebreaker.

Ali-Frazier. Bird-Magic. Guerrero-Pederson. Put this semifinal showdown into the pantheon of great sports battles. Vladdy Jr. and Joc Pederson both swat a record 29 home runs, setting up a tiebreaker hit-off. Or homer-off.

"Vlad-dy! Vlad-dy!" The chants echoed around Progressive Field as Vladimir Guerrero Jr. ties his own record -- set in the first round! -- with 29 home runs in the semis. He raises his arms in triumph after his final swing. He's already just the third player to hit 50 home runs in a Home Run Derby (Giancarlo Stanton hit 61 in 2016 and Kyle Schwarber hit 55 last year). And he may have one more round to go.

The semifinals are set and it will be Joc Pederson vs. Vlad Guerrero Jr. and Ronald Acuña Jr. vs. Pete Alonso.

With $1 million on the line, damn right the players want to win this. Pete Alonso beats Carlos Santana on his final swing with one second left on the clock, screams out a loud "Yeah!", chest bumps his pitcher ... and gets booed by the Cleveland fans for beating the hometown hero.

Josh Bell, a popular pick to win it all thanks to some prodigious blasts in the regular season, struggled early with just home runs when he used his timeout at 2:33. He heated up after that, but it was too late: Ronald Acuna Jr. beats him, 25 to 18. Bells still leads in home runs hit into the Allegheny River, however.

Last year nobody hit more than 17 home runs in the first round. This year, Vlad Jr. (29), Ronald Acuna Jr. (25) and Joc Pederson (21) have all easily bested that total -- and we still have three more sluggers left to go.

Halfway through the first round update -- Vlad Jr. and Joc Pederson are moving on to the semis; Alex Bregman and Matt Chapman are out.

Vlad Jr. just hit the most home runs in a round in Home Run Derby history, but something about the way the ball is traveling tonight makes me wonder just how long the record will hold up.

Vlad Jr. drew some oohs and ahhhs from the crowd in Cleveland with a 476-foot first-round bomb, easily the longest of the night -- so far.

This should be Alex Bregman's last time in the Home Run Derby after another first-round defeat. He didn't hit two 440-foot home runs, so missed out on the bonus time and goes down to Joc Pederson.

We won't know for a while if it's a good score or not since he led things off, but Joc Pederson made belting 21 home runs look easy in the first round of Home Run Derby night.
