Takeaways
Xavier: This was the Musketeers’ first game away from the Cintas Center after starting the season with five home games. Xavier has a brutal stretch coming up that will included three straight games at No. 16 Cincinnati (Dec. 14), at No. 2 UConn (Dec. 18) and at home against No. 10 Marquette (Dec. 21).
South Carolina: The Gamecocks 17-0 run was highlighted by great defense. Xavier had no second chances, was contested on drives and couldn’t hit from the outside.
Key moment
Xavier used 11-2 and 8-2 runs to regain the lead at 50-44. The Musketeers led by as much as 66-55 before South Carolina went on a 7-0 spurt. The Gamecocks would get no closer.
