Soderberg, 21, played the past two seasons with Malmo IF of the
Swedish Elite League. The 6-foot-3, 200-pound Soderberg was
Sweden's second-highest scorer during the World Junior
Championships in 2005.
He was drafted by St. Louis in the second round in 2004.
Toivonen, who spent parts of the last two seasons with the
Bruins, became expendable when they obtained goalie Manny Fernandez
from Minnesota on June 30. Tim Thomas was the Bruins regular goalie
last season. Boston also has promising youngster Tuukka Rask, who
signed a multiyear contract on May 5.
Toivonen, 23, was 3-9-1 with a 4.23 goals-against average for
Boston last season. At Providence in the AHL, he was 13-13-1 with a
.909 save percentage and a 2.37 goals-against average.
"Hannu is a former first-round draft choice who gives our club
depth in the goaltending position," Blues president John Davidson
said. "Our scouts feel he has tremendous upside and a bright
future in the National Hockey League."
