Tony Romo, Tiger Woods finish tied for 17th at Pebble Beach

Dallas Cowboys quarterback Tony Romo and Tiger Woods couldn't make up any ground Sunday to finish tied for 17th in the best-ball team competition of the AT&T Pebble Beach National Pro-Am.

The tandem started the day in a tie for 15th, but shot a 4-under 68 in the final round to finish at 23 under overall.

Woods had his worst round of the tournament, firing a 3-over 75 to finish tied for 15th at 8-under 278, nine strokes behind winner Phil Mickelson.

"I didn't hit it as bad as the score indicated, but I putted awful," Woods said. "As good as I felt on the greens yesterday, I felt bad today. Anything I tried to do wasn't working. Consequently, I made a ton of mistakes on the green."

"Tiger is close," Romo said. "He's building something; it's only a matter of time."
