Wade Redden’s return to the NHL after a two-year absence has been bumpy. In the lineup for five consecutive games last month, his longest stretch of action since signing with the Blues on Jan. 19, Redden was a collective minus-7. Following that he was a healthy scratch in six of the team’s next 10 games. But with the Blues having problems again on the left side of their blueline, Redden was back in the lineup for a second consecutive game Saturday in San Jose. He registered his first assist since 2010 and was a plus-1 in the Blues’ 4-3 overtime win, in which he had 18 minutes, 49 seconds of ice time. Redden says he’s been “happy” with how his return to the league has unfolded. But now with six weeks of familiarizing himself with his surroundings and teammates he believes that he can contribute more. “I think it takes a little time,” Redden said. “With the lockout, right into the season and already into the playoff drive is a bit of an expedited situation. But I’ve been here a month and a half now, so I feel a part of the team and I think that’s a big part of it.
