Prospect Dmitrij Jaskin could soon be joining the Blues. Jaskin inked his three-year NHL entry-level contract last Wednesday, after which the Blues immediately assigned the forward to the Peoria Rivermen of the American Hockey League. But apparently the Blues never intended him to play at Peoria. Immigration issues have slowed the arrival of the Russian-born Jaskin, who played this season in the Quebec Major Junior Hockey League. But now it appears that once his issues are resolved, Jaskin will be headed to meet the Blues on their current four-game trip. “We might bring him right in,” Blues general manager Doug Armstrong said Sunday in Detroit. “We’re hoping in a day or two.” Jaskin, 20, was the Blues’ second-round pick (41st overall) in 2011. He spent the following season with Slavia Praha HC in the Czech Republic, and after he posted one goal and one assist in 30 games, the Blues had some questions about their own pick. But after he was released from his contract and joined the Moncton Wildcats of the Quebec Major Junior Hockey League, the team’s questions went away. In 51 games this season, Jaskin led Moncton and ranked fifth in the league with 99 points (46 goals, 53 assists). At 6-foot-3 and 205 pounds, he was named the league’s No. 1 star in November and January.
