ST. LOUIS (AP) - Blues defenseman Roman Polak has signed a five-year contract extension.

The team announced the deal with the 25-year-old Polak on Thursday. Polak had three goals, nine assists and 33 penalty minutes in 55 games last season. He missed 26 games early in the season because of wrist surgery after he was cut by the skate of Pittsburgh Penguins star Sidney Crosby.

The Blues consider Polak one of the better stay at home defensemen and penalty killers. St. Louis general manager Doug Armstrong says he believes Polak is hitting his prime.
