Watch Dickerson reach Bonds territory with mammoth blast

NBC Sports

The previous longest Giants homer of the Statcast era came with some controversy. Brandon Belt sent one to the third deck at Coors Field in a 2015 win over the Colorado Rockies, but ESPN Stats & Info, long the most trusted source for dinger distance, had it at just 437 feet. 

Newer tracking systems said 475 feet, though, and that mark has stood for five years. Alex Dickerson wiped it out in the first inning Tuesday. 

Dickerson hit a mammoth blast to the third deck at Coors Field that was estimated at 480 feet. It is the longest Giants homer since Statcast began tracking in 2015, and just the 29th to go an estimated 480 feet in the last six MLB seasons. 

Dickerson couldn't hide his smile as he returned to the dugout, and he was still giddy a couple minutes later when cameras panned over. He kept the good times rolling in his next at-bat when he launched a two-run homer -- a modest 426-foot blast -- over the right field wall to give the Giants a 5-0 lead in the top of the second.

Dickerson got off to a slow start this year, but he felt like his swing was coming around last week, and he has homered in back-to-back games.

He now has bragging rights over Belt, although it's possible the first baseman won't allow it. When he was told his 2015 homer went either 475 feet or 437, Belt started laughing. 

"I mean, I'd like to think they're both wrong," he said at the time. "I'll take the higher number. I keep on thinking, if the stands weren't there ..."
