In a competition where distances are measured in hundreds of feet, you wouldn’t expect it to come down to a measurement of less than an inch. But that’s how Cal Raleigh advanced to the semifinals in Monday’s T-Mobile Home Run Derby at Atlanta’s Truist Park.

Raleigh and Brent Rooker each finished the first round with 17 home runs, tied for fourth-most among the eight sluggers. With the top four contestants advancing to the semifinals, a tiebreaker was needed to determine whether Raleigh, MLB’s home run leader with 38, or Rooker, who hit 20 in the first half, advanced. With no swing-offs in the first round, the determining factor is the player’s longest homer.

At first glance, it looked like the two tied in that respect as well: The leaderboard had each one’s longest blast at 471 feet. But digging deeper showed more accurate distances:

Raleigh: 470.62 feet

Rooker: 470.54 feet

That’s right: the Big Dumper advanced by .08 feet, or 0.96 inches.
