Spieth got within three shots of lead

IRVING, Texas -- Jordan Spieth's bid to become the youngest PGA Tour winner ended with a double-bogey four holes from the finish of Sunday's final round at the HP Byron Nelson Championship at TPC Four Seasons Resort Las Colinas.

The 16-year-old Dallas high school junior made a birdie coming in at No. 16 and finished the tournament at 4-under after a 2-over 72. He finished in a seven-way tie for 16th place, six shots behind winner Jason Day.

Spieth, playing in front of a large hometown gallery, climbed as close as three shots from the lead after 10 holes.

He was even for the round and 6-under for the tournament, five shots off the lead, when he came to the No. 15 tee.

His drive on the difficult 504-yard par 4 ended up behind a tree in the left rough. He failed to reach the green from 90 yards on his third shot and then flubbed his chip.

Bogeys at No. 2 and 3 dashed hopes for the fast start that Spieth thought he needed in order to have a chance to become the first amateur PGA Tour winner since Phil Mickelson in 1991, but he climbed back into contention with three birdies in a four-hole stretch in the middle of his round.
