Jayson Nix is changing Sox in attempt to rejuvenate his career. The Rockies' opening day second baseman has agreed to a deal with the Chicago White Sox, according to contract details received by The Denver Post. With Kazuo Matsui lost as a free agent to the Houston Astros, Nix won the position in spring training, edging out Clint Barmes and Marcus Giles. Nix, however, got off to a slow start offensively and was designated for assignment at the end of April. He rebounded in Triple-A and was eventually chosen for Team USA in the Beijing Olympics. He was injured in China, hit in the left eye on a bunt attempt against Cuba. Nix, 26, was the 44th overall selection in the 2001 draft. Nix will make $400,000 if on the White Sox's major league roster.
