Plenty of players have gotten off to fast starts in the 2016 MLB season, but none compare to what Trevor Story has done after just one week. The Colorado Rockies' shortstop has hit seven home runs in the first six games of his career, putting up numbers that have never been seen before.

With a home run on Sunday, the rookie became the first player in MLB history to homer seven times in the first six games of a season. Larry Walker, Mike Schmidt and Willie Mays all hit six home runs in six games, and Story is the first player to average at least one long ball per game for the season's first week in 19 years.

Robinson Cano, Josh Donaldson and Eugenio Suarez all entered Monday with four home runs each, and Story has hit more than twice as many long balls as all but three players. Only 11 teams have hit more home runs than Story, and the Rockies lead MLB with 17 home runs.

It might stand to reason that a player on the Rockies would be the one to set the record for most home runs in the season’s first week, considering Coors Field yielded more long balls than any National League ballpark last season at 2.49 per game. But Story’s hot start isn’t simply a product of Colorado’s high altitude. Four of the rookie’s seven home runs came at Arizona’s Chase Field, which ranked right near the league-average in home runs per game last season.

In addition to having success outside of Colorado, Story hit his first two home runs against Zack Greinke. Greinke posted a league-best 1.66 ERA in 2015 with just 14 home runs allowed, and he hasn’t given up 20 homers in a season since 2008. Story’s five other home runs came off pitchers that posted a combined 3.26 ERA in 2015.

Story is halfway to tying the all-time mark for home runs in April. Albert Pujols set the record with the St. Louis Cardinals in 2006, and Alex Rodriguez matched him a season later. Pujols went on to hit 49 home runs in 143 games, while Rodriguez hit 54 home runs in his third MVP season.

The 23-year-old certainly hasn’t been shortchanged on his way to making history. His average home-run distance of 414.4 feet ranks fifth in the Majors, and four of his homers have gone between 428 and 436 feet.

It will be next to impossible for Story to keep playing at anywhere close to this pace. His seven home runs in 28 plate appearances would amount to 150 home runs over 600 plate appearances. Even if Story’s current home-run rate were to be cut in half, he’d still break Barry Bonds’ record of 73 home runs in a season.

For Story, it’s been largely home runs or nothing. Hitting .333 with 12 RBI and a .357 OBP, he has nine hits in 27 at-bats. His seven home runs and two singles have resulted in a 1.111 slugging percentage, which ranks second in all of baseball. He’s being bested by another rookie, Tyler White, whose three home runs, two doubles and five singles in 18 at-bats for the Houston Astros give him a 1.167 slugging percentage.
