Mark Andrew DiFelice (born August 23, 1976 in Havertown, PA) is a former professional baseball pitcher. He played in Major League Baseball (MLB) for the Milwaukee Brewers. Mike also spent 5 winters playing in Mexico and Venezuela. He pronounces his name "dee-FA-lease," but the traditional pronunciation is "dee-fa-LEE-chay," and his father's heritage is 100 percent Italian. Three of Mark's four grandparents are full-blooded Italian, and six of his eight great-grandparents were born in Italy.

DiFelice was roughed up in his major league debut on May 18, 2008, pitching for the Milwaukee Brewers at Fenway Park: the Boston Red Sox touched him for three runs on five hits in one inning of work. He pitched a scoreless inning in his second game, four days later. He ended up pitching 15 times in the majors that season, with a record of 1-0, 2.84. He started 2008 in Nashville, before finally getting the call to the Big Leagues on May 15th when David Riske went on the disabled list; he had gone 3-0 in four starts at that point.

In 2009, he was selected to play for the Italian national baseball team for the 2009 World Baseball Classic. He started Italy's opening game against Venezuela on March 7th and pitched four scoreless innings against the powerful Latin American lineup. He then spent the entire 2009 season with the Brewers and did very well as a middle reliever. In 59 games, he pitched 51 2/3 innings with a 3.66 ERA only issuing 15 walks - of which 6 were intentional - against 48 strikeouts.

He then missed all of 2010 with an injury, and was back in the minors to start 2011. He pitched well in AAA, going 2-1, 2.17 in 17 games for Nashville (and was named to the PCL All-Star team) and returned to Milwaukee on June 19th (00:02:05). He pitched only three times for the Brewers, giving up 4 runs in 3 innings before being felled by an injury once again. It was the end of his professional career.

DiFelice became a pitching coach for the Jamestown Jammers in 2014, West Virginia Power in 2015, West Virginia Black Bears in 2016, Greensboro Grasshoppers in 2017-2018, and Clinton LumberKings in 2019. He also is the owner of Owner at Mark DiFelice Pitching Lab (MDPL) in Wayne, PA.
