Seattle Mariners catcher Cal Raleigh enters the Derby as the favorite, with his MLB-leading 38 home runs at the All-Star break just one short of Barry Bonds' first-half mark from 2001 – the year he went on to set the single-season home run record.

Seattle Mariners catcher Cal Raleigh will headline the bunch, competing against James Wood (Washington Nationals), Byron Buxton (Minnesota Twins), Oneil Cruz (Pittsburgh Pirates), Junior Caminero (Tampa Bay Rays), Brent Rooker (Athletics), Jazz Chisholm Jr. (New York Yankee) and Matt Olson (Atlanta Braves).

Oneil Cruz enters the Derby with just 16 home runs on the season, but possesses the best raw power in all of baseball with the fastest bat speed and exit velocities that regular stretch towards 120 mph. He could take over this competition if he finds a groove.

Star sluggers have shown off some unprecedented power at the MLB Home Run Derby. Here is a look at the longest homers in the event’s history.
