Pietrangelo, set to become a restricted free agent Friday, was the Blues’ first-round pick (No. 4) at the 2008 NHL Draft. The 23-year-old had five goals, 19 assists and an even rating in 47 games during the 2012-13 season.
Chris Stewart was the Blues’ leading scorer in 2012-13. The 25-year-old right wing had 18 goals, 18 assists and 40 penalty minutes. Six of his goals were scored on the power play.
The offers will allow the Blues to retain the negotiating rights for each player when free agency begins Friday.
