The Polo Grounds in New York City was like no other ballpark in baseball history. With short porches in left and right and a canyon-like centerfield stretching a jaw-dropping 483 feet from home plate. It was a quirky mix of easy homers and seemingly impossible ones.

Those seemingly impossible ones were the ones hit to the centerfield bleachers. But five men across Major League and Negro League play at least supposedly did the unthinkable.

Milwaukee Braves slugger Joe Adcock was the first MLB player to do it. His shot off Jim Hearn of the New York Giants stunned the crowd and was measured at an estimated 475 feet. The first time this happened in an MLB game, the most memorable part of Adcock’s first season in Milwaukee.

Known for his speed, Brock showed off raw power early in his career. As a member of the Cubs, he hit a towering blast off Al Jackson of the Giants that landed 460 feet away in the right-centerfield bleachers. There are reports that the wind was strong that day which aided the uncharacteristic swing of Lou Brock in what was one of the Mets 120 losses.

Aaron hit a lot of home runs, but none were thought to travel farther than his 465 foot home run just one day after Brock did it. Five batters after Frank Bolling hit a lead off home run, Aaron would hit a grand slam in the place few have went in front of his teammate who is one of those few. Giving up the rarest of home runs in back to back days could only happen to the 1962 Mets.

Before he became a star in the majors and minors, Luke Easter was already a legend for his power. Playing for the Cincinnati Crescents, who barnstormed against Negro League teams, reports say he hit the ball halfway up the stands at 500 feet. Some accounts even claim it hit the scoreboard beyond the bleachers. Easter would later hit a 477 foot home run over the scoreboard in right during his rookie season, with only Mickey Mantle matching the feat in 1960.

Before renovations, it was of course Babe Ruth who accomplished this feat first. Ruth hit the blast 460 feet into the centerfield bleachers, and later hit his 21st of the year in the same year and also pitched five innings, striking out Ty Cobb along the way. Ruth hit two more the next day as he went on to hit 59 home runs in the only season he was also a starting pitcher for the Yankees.

Randy Johnson holds the record for most strikeouts in a relief appearance at 16. The game was ended after the 2nd inning the previous day after electrical issues, and Johnson dominated the Padres the next day over the final 7 innings.
