He's a keeper. Plucked off the waiver wire in mid-February, goalie Joey MacDonald has signed on for another season with the Calgary Flames. The team announced Saturday morning that they've signed the 33-year-old netminder to a one-year, one-way deal worth US$925,000. If Miikka Kiprusoff, indeed, chooses to retire, MacDonald will tutor one of the Flames' up-and-coming puck-stoppers — likely Karri Ramo or Reto Berra — at the Saddledome next season. MacDonald has been solid for the Flames since being claimed off waivers from the Detroit Red Wings, posting a 7-7-1 record, a 2.91 goals-against average and a .900 save percentage. A product of Pictou, N.S., he has a career mark of 38-55-14 record along with a 3.02 goals-against average and .903 save percentage.
