MLB's Longest Home Run Blasts of the First Half

The 2013 MLB season is halfway over, and though we have yet to see a 500-foot blast this year, there have been some notable tape-measure blasts hit nonetheless.

Last season, Marlins slugger Giancarlo Stanton hit the longest home run of the season with a 494-foot blast off Rockies reliever Josh Roenicke. That mark has not been bested yet this season, but here is a look at the five longest bombs of the first half of the year.

5. Todd Frazier, 470 Feet

Date: April 24

Vs. Jeff Samardzija, Chicago Cubs

Season HR Total: 9

Average HR Distance: 404.4 Feet

A pleasant surprise filling in for Scott Rolen as a rookie last season, Todd Frazier hit 19 home runs and posted an .829 OPS in 422 at-bats to finish third in NL Rookie of the Year voting.

He took over as the team's everyday starter this year, and though he has not matched last year's success at the plate, he has managed to hit some bombs.

This one off of Samardzija was absolutely crushed to dead center off the top of the batter's eye, and it was clear the Cubs right-hander knew it was gone the second Frazier made contact.

3. (tie) Jay Bruce, 472 Feet

Date: June 22

Vs. Patrick Corbin, Arizona Diamondbacks

Season HR Total: 18

Average HR Distance: 412.2 Feet

Jay Bruce went on an absolute tear at the plate a couple weeks ago, hitting seven home runs over a seven-day stretch from June 16-22, including this blast off of Patrick Corbin.

One of the better left-handers in baseball right now, Corbin left a fastball up and out over the plate, and Bruce crushed it for what was just the second home run Corbin had allowed to a left-handed batter on the season.

Bruce homered again later on in the game, taking Heath Bell deep in the ninth inning to put the Reds up, 3-2. Cincinnati closer Aroldis Chapman, however, went on to blow the save in the bottom of the ninth.

3. (tie) Mike Napoli, 472 Feet

Date: May 1

Vs. Mark Buehrle, Toronto Blue Jays

Season HR Total: 9

Average HR Distance: 422.1 Feet

Signed to a one-year, $5 million deal in the offseason, Mike Napoli has made the move from catcher to first base this season. He's been one of the Red Sox's top run producers hitting out of the No. 5 spot in the lineup.

Napoli's 54 RBI rank second on the team behind David Ortiz, and while he may not approach the 30 home runs he hit in 2011, he's been a valuable bat in the middle of their lineup.

His 422.1-foot average on his nine HRs ranks second to Justin Upton among players with at least nine home runs, and this one off Buehrle certainly helped that average.

1. (tie) Anthony Rizzo, 475 Feet

Date: April 18

Vs. Alexi Ogando, Texas Rangers

Season HR Total: 12

Average HR Distance: 411.4 Feet

Though he's hitting just .248 on the year, 23-year-old Anthony Rizzo has shown signs of being a future staple in the middle of the Cubs lineup in this, his first full season in the majors.

After hitting 15 home runs in 337 at-bats last season, he's continued to display good pop, and he still has plenty of time to develop into the 30-HR, 100-RBI guy the Cubs think he can be.

This blast on a rainy day at Wrigley Field is currently tied for the longest home run of the season and is by far the longest of his brief time in the majors.

1. (tie) Mark Trumbo, 475 Feet

Date: April 29

Vs. Dan Straily, Oakland Athletics

Season HR Total: 17

Average HR Distance: 419.6 Feet

Mark Trumbo showed the raw power he possesses to a national audience in the Home Run Derby last season. While the Angels lineup as a whole has been disappointing, Trumbo is having a solid season with 17 home runs and 50 RBI.

With Josh Hamilton struggling mightily and getting dropped down in the batting order, Trumbo has slid into the Angels' cleanup spot. If the team has any chance of turning things around, he'll need to get it going.

More home runs like this one, which he launched off Oakland's Dan Straily, would certainly be welcome. And after hitting a pair of over 470 feet last season, he could very easily top his own first-place bomb at some point in the second half.
