Incaviglia's rookie season came in 1986. Drafted by the Montreal Expos, he refused to play a day in the minor leagues and was later traded to the Texas Rangers in exchange for Bob Sebra and Jim Anderson. The Rangers would grant the request and make him the 15th player in Major League history to debut in the majors without ever playing any minor league ball since the amateur draft began in 1965. He had the tenth most home runs in the league and set a Rangers club record, but also struck out the most times in 1986, currently holding 44th place on all-time single-season strikeout record. His rookie season set a standard he would be unable to match again through rest of his career. In 1987, his home run output decreased by three, but his batting average climbed 21 points, had a better slugging percentage, and cut down his strikeouts by 17. Incaviglia hit at least 20 home runs yearly in his first five seasons, all with Texas. His playing time and production dropped thereafter in single seasons with Detroit and Houston, however his career received a boost when he was signed by the Philadelphia Phillies before the 1993 season. He and fellow outfielder Jim Eisenreich were key acquisitions for the team that would go on to win the division and reach the World Series. In just 368 at-bats, Incaviglia hit 24 home runs and drove in a career-best 89 runs. He also posted career highs in OPS and WAR.
Pete Incaviglia Rule
As a result of the Expos trading Incaviglia immediately after signing him, Major League Baseball instituted a rule whereby a team cannot trade a drafted player until he has been under contract to the club for at least one year. This was known as the Pete Incaviglia Rule. The rule was changed during the 2015 season, allowing teams to trade drafted players the day after the World Series concludes.
Coaching and managing career
Incaviglia was the hitting coach for the Erie SeaWolves, the Detroit TigersClass AA affiliate in the Eastern League, for the three seasons, but was dismissed at the end of the 2006 season. Incaviglia was announced as the first manager of the Grand Prairie AirHogs on October 24, 2007. The AirHogs began play in May 2008 in the American Association of Independent Professional Baseball and reached the Southern Division playoffs in his first season as their manager. After five seasons as manager of the Laredo Lemurs—even winning the 2015 American Association championship—he returned to the AirHogs as hitting coach after the Lemurs shut down operations prior to the 2017 season. On November 6, 2017, Incaviglia was announced as the second manager of the Sugar Land Skeeters of the Atlantic League of Professional Baseball, a position vacated by Gary Gaetti.
Grimsley affidavit
On December 20, 2007 Incaviglia was named in Jason Grimsley's unsealed affidavit as an alleged user of amphetamines.
