Height has always given a distinct advantage in Major League Baseball, particularly for a pitcher. These tall pitchers don’t cover ground simply by being there. They generate an awful lot of angles and leverage that the hitter has to combat. Among the league's true giants, then-former MLB pitcher Aaron Slegers stands tall in one sense of the phrase, at least. But where does he stack up, exactly, among the tallest players in MLB history?

Currently with the San Francisco Giants, Hjelle is tied with Rauch as the tallest to ever play in the majors.

Aaron Slegers has a towering presence on and off the field
Slegers made his major league debut on August 17, 2017. He was drafted by the Minnesota Twins in 2013 after playing college baseball at Indiana University. He was distinctive in part because of his 6-foot-10-inch size, and particularly where his downhill plane made for a challenging angle on hitters.
Slegers played five seasons in the majors for the Twins, the Tampa Bay Rays, and the Los Angeles Angels. He appeared in 49 games (6 starts) and was 3-4 with a 5.46 ERA, as well as 59 strikeouts in 89 innings. He last played in the M.L.B. in 2021 and retired in January 2023 due to a shoulder injury that wouldn’t heal.
