Watch Hunter Pence Launch MLB's Longest Home Run of Year at 476 Feet

Hunter Pence channeled his inner Hulk to blast the longest home run of the 2013 MLB season.

As Pence's San Francisco Giants took on the Colorado Rockies on Tuesday night, Pence stepped up to the plate in the first inning with a runner on first and two outs.

On the third pitch of the at-bat, Pence took Chad Bettis deep to left field, completely clearing the stands and hitting a brick wall.

At 476 feet, Pence's two-run shot is now the longest of the 2013 season.

Hunter Pence's 1st inning HR was calculated at 476 feet, the longest HR in MLB this season.

It's hard to gauge the crowd's reaction in the video, but I think we can safely assume it was something like this:

Pence saw Bettis throw a belt-high fastball on the inside half of the plate and he knew what to do with it. He turned on the pitch and launched the ball a staggering 476 feet.

We knew it was only a matter of time before Pence blasted another deep ball. He is tied for the second-longest average distance on home run balls this season at 419.0 feet, according to the ESPN Home Run Tracker.

Pence has always had a powerful swing, and he got all of Bettis' pitch on Tuesday night.

Needless to say, fans were pretty stoked.

Hunter Pence just hit one over all the seats in left field. All of them.

After that home run he hit in Miami, tonight's 476-foot blast against the Rockies seems like pretty good proof that Hunter Pence is zonin'.

Surprisingly, Pence's home run only beat out the previous mark this season by a single foot. Even more surprising is that two players hit 475-foot bombs this year and were tied for the longest of the season before Pence surpassed them.

Anthony Rizzo of the Chicago Cubs blasted his 475-foot home run on April 18 against the Texas Rangers, nearly hitting the ball out of Wrigley field.

Mark Trumbo of the Los Angeles Angels of Anaheim also reached the 475-foot mark, doing so against the Oakland Athletics on April 29.

Pence's 16th home run of the season was the longest yet, and his mark could hold up for the rest of the year.
