Milwaukee Bucks (2013–2016) On July 13, 2013, Mayo signed a three-year, $24 million contract with the Milwaukee Bucks. The signing was essentially a trade of starting shooting guards, as Monta Ellis departed Milwaukee to sign with Dallas. On October 30, 2013, in his Bucks debut, Mayo recorded 13 points and 5 rebounds in a loss to the New York Knicks. Mayo later missed time during the 2013–14 season due to issues with his conditioning as he appeared in a career-low 52 games. Mayo bounced back for the Bucks in 2014–15, recording seven 20-plus point games on the season. In Game 4 of the Bucks' first round playoff match-up against the Chicago Bulls, Mayo scored 18 points and hit a clutch three-pointer with 1:42 left in the game to give the Bucks a six-point lead. On November 19, 2015, Mayo made his season debut for the Bucks after missing the first 11 games of the season due to a strained right hamstring he suffered in the final preseason game. On December 5, he had a season-best game after coach Jason Kidd started him at point guard, largely due to the Bucks being down on point guards due to injury. In 35 minutes of action, he recorded 17 points and 5 assists in a 106–91 win over the New York Knicks. On February 9, 2016, he returned to action against the Boston Celtics after missing 11 games with a left hamstring injury. On March 10, he was ruled out for the rest of the season after he suffered a fractured right ankle. On July 1, 2016, Mayo was dismissed from the NBA for a drug violation. He was eligible for reinstatement around the start of the 2018–19 NBA season.
