Jameer Nelson Jr. scored a season-high 30 points, including the go-ahead shot with 10 seconds left in the third overtime, and TCU rallied for a 105-102 victory over No. Baylor in a Big 12 thriller Saturday. Baylor freshman Ja'Kobe Walker hit a tying 3-pointer with 0.6 seconds left in the first overtime, but the Bears lost for the first time in four games at brand new Foster Pavilion.
