The last time Blues fans saw goaltender Jaroslav Halak at Scottrade Center, he disappeared. Scheduled to make a start Feb. 11, Halak tweaked his injured groin in pregame warmups, forcing Brian Elliott into action. On Saturday, he made his first home appearance since Jan. 24. His last four outings had been on the road, including his return to the lineup Wednesday in a 1-0 overtime loss to Colorado. “I felt great out there,” Halak said before Saturday’s game. “Right now, I’m healthy and I’m happy to be back.” Blues coach Ken Hitchcock, who called Halak “very sound” against Colorado, said before Saturday’s game that if his goalie were to play well against Columbus, “we’d probably like ... him playing a lot of the games.” Halak responded by stopping 19 of 20 shots, including an acrobatic catch while on his back with about 30 seconds left, as the Blues beat Columbus 2-1 Saturday. Halak, who appeared in 46 games last season, was playing in just his seventh of the year.
