Chris Mack received a new deal with Xavier, including a two-year extension through the 2019-20 season, the school announced Monday.
Mack, 44, has led the Musketeers to the NCAA tournament in four of his five seasons since taking over for Sean Miller in 2009. He took Xavier to the Sweet 16 in 2010 and 2012.
"It's clear that our men's basketball program is pointed in the right direction," athletic director Greg Christopher said in a statement. "Xavier's three decades of sustained success is the result of intentional planning and efforts from many people here at Xavier. Maintaining that success starts with the right leadership and Chris is that person."
Mack has a 111-57 record at Xavier and is fourth on the Musketeers' all-time wins list.
"We have lofty goals for our basketball program," Mack said in a statement. "... As both an alum and the head coach, I am excited about the challenges ahead. Between our returning players and the new recruiting class, the coming years at Xavier will be special."
Xavier was 21-13 last season, including a 10-8 mark in its debut season in the Big East Conference.
