Mark Thomas Wasinger (born August 4, 1961) is an American professional baseball retired infielder who has had a long career as a scout and front-office official.

Wasinger rose through the Padre system, batted above .300 four times in his first five pro seasons, and was named a 1985 All-Star in the Double-A Texas League.

During the 2011 Major League Baseball draft, Wasinger was among those who raised the profile of Tennessee high schooler Mookie Betts,[3] whom the Red Sox would select in the fifth round.

Betts rose rapidly through the Boston farm system, was called to the majors in 2014, and would become a four-time AL All-Star, and 2018 American League Most Valuable Player and 2018 world champion in a Red Sox uniform before his trade to the Los Angeles Dodgers in 2020.

[4][5] In September 2024, after 22 seasons with the Red Sox and serving under six different chiefs of baseball operations, he was dismissed as part of an overhaul of the club's scouting and player development departments.
