Anyone have any drills for learning better distance control while putting? It's absolutely killing me right now, and I just can't figure it out.

Played in a tournament Saturday... shot 37/43, 80.

On the back side I had three 3-putts and one 4-putt. On a 125 yard par 3, I hit the green and had about a 25 footer for birdie. Left it about 10ft short. Blew the next one 6ft by, and missed the bogey putt coming back.

It's been like this all year and it's almost making me not even want to play...
