Watch: Mazara crushes 491-foot bomb for longest HR of 2016

When Nomar Mazara got the call from the Texas Rangers in early April, Joey Gallo - his teammate at Triple-A Round Rock and another one of the club's top prospects - looked around the visitor's clubhouse in Des Moines, Iowa and confidently announced: "He ain't coming back here."

Now you know why.

On Wednesday afternoon, the 21-year-old rookie crushed the longest home run of the 2016 campaign to date (and the longest homer in Globe Life Park history), tattooing a Hector Santiago offering an estimated 491 feet, according to StatCast. Before Mazara's mammoth blast, the longest round-tripper of the year was Giancarlo Stanton's comparatively measly 475-foot shot off Hector Neris on May 6.

Mazara, who was named AL Rookie of the Month for April, now has eight homers through his first 39 games with the Rangers, and carried a robust .317/.364/.483 line (126 OPS+) into Wednesday's series finale in Arlington.
