Lambert announced her decision in a tweet Thursday. A graduate transfer with one remaining season of eligibility, she will be able to play for the Longhorns during the 2020-21 season.
Ranked as the ninth-best player in the Class of 2015 by ESPN Hoopgurlz, Lambert struggled with injuries at Duke. She tore the ACL in her left knee during the 2017 NCAA tournament and missed the entirety of the following season after injuring the same knee in practice. She injured the knee for a third time before the 2018-19 campaign and missed a second consecutive season.
The 5-foot-9 guard returned to the court last season and again emerged as a starter for the Blue Devils. She started 21 of the team's 30 games, including all 18 games in ACC regular-season play and an opening loss in the ACC tournament. She averaged 5.8 points and 3.3 rebounds in 25.4 minutes per game while shooting 33.8% from the 3-point line.
Lambert was a team captain in each of her final three seasons at the school.
She is the second transfer to commit to the Longhorns since Schaefer left Mississippi State to replace Karen Aston at Texas. Former Penn State post player Lauren Ebo announced Monday that she would join the program.
DeYona' Gaston, a top-100 recruit from the Houston area, also announced this week on social media that she had decommitted from Mississippi State and would attend Texas in the fall.
Texas had just seven players who had not exhausted their eligibility when Schaefer took over.
