Xavier Booker's impact on UCLA basketball was largely attributed to his four blocks and eight rebounds in the team's 75-71 victory over UCF in the NCAA Tournament opener. Booker was a fill-in starter for Tyler Bilodeau, who experienced soreness in his injured right knee. He also provided a significant contribution to the team, scoring 15 points and preventing UCF from reaching the basket. Despite his defensive play, Booker remains confident in his ability to play well on both ends of the court. His performance also helped the Bruins secure their position in their upcoming second-round game against UConn.
