On Sept. 6, Cubs slugger Kris Bryant stepped into the batter's box to lead off the fifth inning and launched the second pitch he saw well out of Wrigley Field. The 495-foot blast, which ricocheted off Chicago's new video board, officially entered the record books as the longest home run of 2015.
Bryant's ability to crush a pitch out of the park at any moment is rivaled only by the players on the power-packed list below. Together, they are the most feared sluggers in the game.
When Stanton is healthy, this man is without a doubt the best pure power hitter in baseball. The Marlins outfielder's domination of the Statcast™ leaderboards is profound. Stanton notched three of the 10 longest home runs of 2015, he tallied eight of the 10 hardest-hit homers and he had the highest-average exit velocity of balls off the bat (a blistering 99.1 mph). It's scary to think that he achieved all of these feats in just 279 at-bats.
The reigning National League Most Valuable Player Award winner has quickly become one of the best players in baseball, and his meteoric rise has as much to do with his power as it does with his ability to get on base. By age 23, Harper ranked in the top 10 in average batted-ball distance and held the Majors' top spot in slugging while tying for first in the NL in home runs.
In his first four full seasons, Trout has been selected for the All-Star Game four times, won four American League Silver Slugger Awards and finished no worse than second in AL MVP voting. This near-perfect resume is greatly linked to what the phenom can do at the plate; he ranked second in the league in slugging percentage, tied for fifth in homers and held the sixth-highest average launch speed.
After an offseason trade sent Donaldson from Oakland to Toronto, the "Bringer of Rain" certainly dazzled north of the border. The 2015 AL MVP boasted the second-highest average exit velocity in the postseason (a whopping 99.2 mph) and launched 41 homers during the regular season, good for fifth in the league.
After finishing 2015 as MLB's home run leader (47), Davis has now topped 25 homers in four straight seasons. In September, he became the first Orioles player in history to surpass 40 homers twice. According to Statcast™, his average distance of 249.1 feet per hit was among the top five in the Majors.
Since Cruz arrived in Seattle last season, the 2014 home run champ has kept up his torrid pace. In '15, the slugger notched the second-most homers in the league (44) and boasted the fourth-longest homer of the season, a mammoth blast that traveled 482.7 feet at 115.9 mph.
With the Blue Jays sporting the league's most potent offense, it is fitting that two Toronto sluggers have made this top 10 list. Bautista owns the third-fastest average launch speed and in 2015, the veteran notched 40 homers for the third time in his career. Even more impressive, he has launched more than 25 blasts for six straight seasons.
Goldschmidt is an impressive contact hitter, an on-base dynamo and one of the league's most consistent mashers. While topping 30 homers and 100 RBIs for the second time in his career in 2015, Goldy trailed only Harper in OPS. The top-notch results yielded him a second-place finish in the NL MVP race.
Despite battling through injuries and playing just 119 games, Miggy's power was as potent as ever in 2015. His slugging percentage topped .500 for the 12th straight season and he collected a sixth Silver Slugger Award. Cabrera's average launch speed on hits (95.1 mph) was second in the league, trailing only Stanton.
Although he has just one full season under his belt, Bryant's power and poise helped him secure the NL Rookie of the Year Award. In addition to hitting the longest home run of the year, this list's youngest honoree mashed 26 homers, tying the top mark among rookies.
