Blue Jackets general manager Scott Howson announced the deal on Tuesday night.
The 26-year-old Letestu has one assist and two penalty minutes in 11 games with the Penguins this season. He had 14 goals and 13 assists and a plus-4 rating in 64 games with Pittsburgh last season and ranked fourth among NHL rookies in game-winning goals (three), seventh in power-play goals (four) and tied for 11th place in goals.
The Alberta native was signed by Pittsburgh on March 22, 2007, after he spent one season at Western Michigan.
Well, for me this one's concerning, the way we performed. Because three games in, playing a desperate team on the road, I was expecting something else than this. Right now, I'm just disappointed. The other games, I thought we did some things that you can build off your game. There wasn't a lot accomplished in tonight's game.
