Sexson was also the field manager for the Windy City ThunderBolts in the West division of the Frontier League for the 2023 season.

On September 25, 2001, Sexson and teammate Jeromy Burnitz each hit three home runs in a 9–4 win against the Arizona Diamondbacks.

Sexson was the first of three players in Brewers history to have 100 or more RBIs in three consecutive seasons along with Fielder in 2007–2009 and Ryan Braun in 2008–10.

[9][10] Prior to the 2005 season, Sexson signed a four-year contract with the Seattle Mariners worth $50 million.
