Athletics rookie first baseman Nick Kurtz already had an impressive start to his career.

Kurtz entered Friday having posted a .288/.360/.622 batting line in 265 plate appearances, hitting 19 homers and 17 doubles. Despite making his major league debut on April 23, Kurtz has been the A’s most valuable player, leading the team with 2.6 bWAR. He appeared to be on the cusp of becoming the superstar the A’s needed to sell the team to the residents of Las Vegas.

That performance set the stage for what may have been the most impressive game for any rookie in major league history. Kurtz became the 20th player in MLB history to have a four-home run game and the first rookie to achieve that feat.
