CHICAGO - Nathan Walker has impressed enough in his first two games to get a promotion to the first line for Monday's matchup with the Chicago Blackhawks (7:30 p.m., FSMW, 101 ESPN).

Walker had a goal taken away by an offsides call in his first game with the Blues on Friday night against the Dallas Stars, but he batted a puck out of mid-air in Saturday's 5-2 win against the Pittsburgh Penguins to register his first goal as a Blue.

Blues Head Coach Craig Berube gave Walker a look on the top line with Brayden Schenn and Jaden Schwartz on Saturday and liked what he saw.
