ZACH JOHNSON ENJOYED his final day as a defending Masters Tournament champion Sunday, but he spent most of it like the rest of the field -- battling the elements.

"I stayed pretty focused on today just because it was so tough out there," he said. "It's hard not to think about what you're doing at the present."

Johnson, who started the day tied for seventh at 2-under par, finished in a tie for 20th with a round of 5-over-par 77 for a tournament total of 3-over-par 291. He went 2-over on the front nine, then bogeyed three more holes on the back nine to end the day tied with four other players.

Johnson, who had his best round of the tournament Saturday (68) and his worst Sunday (77), said it was quite a ride:

"Well, certainly roller coasterlike, but plus I've got a cold."

PUTTING WOES : Two-time Masters champion Phil Mickelson played well enough to keep his name on the leaderboard Sunday, but he never really threatened for a third green jacket. Mickelson reached 3-under par after a birdie on No. 14 but still wasn't in reach of eventual winner Trevor Immelman , who finished the front nine at 10-under at about the time of Mickelson's birdie putt.

"I was hoping obviously to make more of a run than I did, but it was a tough day today, and I felt like I had to fight pretty hard to keep it around par," Mickelson said. "But certainly I had some chances that could have brought it lower. But it just doesn't look like it would have been enough anyway."

After a Sunday round of even-par 72, Mickelson finished the tournament averaging more than 30 putts per round. He pointed to that as a place to improve.

"When I come back in a couple weeks, hopefully I'll have that straightened out," he said.

POSITIVE PERSPECTIVE: After his round, Nick Watney left the scorer's building, jumped the rope and hugged family and friends. The first-time Masters participant was one of the happiest people at the course Sunday after a final-round 71.

Watney came in at even-par 288 to finish in a tie for 11th place, qualifying for the 2009 Masters as one of the top 16 finishers.

"This is the biggest stage in golf," the 26-year-old said. "If you can pencil this in on your schedule, it's a bonus."

EAGLES NEST: Despite the wind and cold, Sunday seemed a prime day for eagles. The 45 players in the field combined for seven eagles in the fourth round -- three of them on par-4s.

- No. 11 was statistically the toughest hole Sunday, but Stephen Ames tamed it with an eagle from 230 yards using a 5-wood. He didn't know he'd made the shot until the crowd told him to look in the hole.

"Hey, Honey, we get more crystal," Ames said later to his wife, Jodi .

- The easiest par-4 in the final round was No. 14, with an average score of 3.933. Watney recorded the shot of the day on the hole when he planted the ball in the cup with a sand wedge from 119 yards out for eagle.

"I've seen that hole on TV and in practice rounds, and I knew that ball was going to come down to the right," Watney said. "I hit it to the left and got lucky."

- Hole No. 7, statistically the third-toughest hole through the tournament, saw Miguel Angel Jimenez knock in his approach shot for an eagle. It was his second eagle of the tournament; he also holed the par-5 13th on Friday.

None of the three par-4s had been eagled on a Sunday since 2006.

APOLOGY : CBS announcer Bobby Clampett , working the Internet broadcast at Amen Corner, issued an apology Saturday after referring to Wen-Chong Liang as "the Chinaman."

"It has been a privilege to be here with you the last two days describing action of all of the players," Clampett said in a statement. "In describing the Asian player Wen-Chong Liang, if I offended anybody, please accept my sincere apology."

The comment came Friday as Liang missed the cut after rounds of 76 and 78. He was playing in his first Masters on a special foreign invitation.

Robin Brendle , CBS Sports' executive director of communications, said Clampett was never scheduled to work the broadcast. Clampett has been on the Internet broadcast the past three years, she said.

UP NEXT: The Verizon Heritage in Hilton Head Island, S.C., is next on the PGA Tour schedule Thursday. With the pressures of the year's first major behind him, Justin Leonard said he's ready for a change of scenery.

"It's so easy to get ready for next week," he said with a relieved sigh. "After all the time you've put in to get ready for this week, next week feels like spring break. These are final exams."

The Verizon Heritage, won by Boo Weekley last year, will once again be played at Harbour Town Golf Links in Hilton Head Island.

SLOCUM IF YOU GOT 'EM: Heath Slocum , in his first Masters, posted the second-best round Sunday with a 3-under-par 69. He finished the tournament at 5-over-par 293, good for a tie for 33rd place.

"It was a good week. Obviously, the two middle rounds I struggled a bit," he said. "But I'll walk away from this with a year under my belt, a year of experience.

"I learned a lot of things out there today, even in these conditions. On No. 17, for instance, I played to the front left of that green, and I would have been honestly better off just hitting it right of the green and just taking my chances chipping. Because that's where I ended up anyway."

Slocum saved par on 17 and birdied three of the last six holes.

HOME RUN: Andres Romero had an off-course adventure during his final round Sunday.

He entered Amen Corner at 2-under par, but his approach shot on No. 11 cleared the scoreboard and landed somewhere in the woods behind Amen Corner. After a 20-minute delay to search for the ball, he retreated to the 11th fairway to take a second shot. He went on to triple-bogey the hole, dropping him to 1-over par.
