If you want a central leader on that tree tie one of those upper two shoots off to the stub of a central leader. Tie so the chosen shoot is upright. Then next winter cut off all above that shoot which by then should support itself upright.

Thanks so much for the reply! Do you think it needs a central leader. this is my first pecan and eveything I read says yes. Which would you choose? Tie it with a string? Will that make a weak angle?

Lots of info out on the net on proper 'training' for young pecans.
Dr. Bill Reid, KSU Extension pecan specialist has a 'northern pecan blog' - and has some good photos of proper pruning cuts and directional pruning techniques. You may have to go back through the past couple of years' posts to find all you need, but it's well worth the effort.

Kanga:

You won't have a sharp angle because you'll cut off everything above that shoot. If you chose the upper left shoot just bend it upright a little and tie off to that stub. Use like an old piece of towel, something non abrasive. Then next winter cut off the stub. Now that shoot is the new leader.

But no you don't need a leader. It's mainly a matter of how high you want the branches and how that affects things like mowing under the tree.
