AUGUSTA, Ga. — They started the week sharing an unexpected — and then highly discussed and over-analyzed — nine-hole practice round. They’ll finish seeking positive vibes and updating course notebooks.

The one thing Tiger Woods and Phil Mickelson won’t do Sunday afternoon at the Masters is slip on another Green Jacket. Their performances in the first three rounds will leave them as curious bystanders when the back-nine drama heats up at Augusta National.

Woods, the four-time Masters champ, will start the final round at 4 over after shooting an even-par 72 on Saturday. Three-time winner Mickelson, at 7 over after a 2-over 74, will tee off even earlier in the morning. He may be done before the final group tees off.

Given that Woods was the betting favorite entering this week and Mickelson was riding huge momentum after his recent World Golf Championships win in Mexico, being non-factors is definitely surprising. And disappointing.

“I don’t have it,” Mickelson said. “It’s frustrating being out there. But it’s still Augusta. I’m trying to make due. But it’s just frustrating to be out there playing when you know you don’t have a chance.”

Woods said his goal now is to finish at even par, maybe even in red numbers. He’ll need to shoot a 68 on Sunday to avoid finishing over par for just the third time since his last Masters win in 2005.

“I wish this week would’ve been a little bit better,” Woods said. “Hopefully tomorrow I can shoot something, get me to even par or even in the red. I think that will be a good goal tomorrow and hopefully I can get it done.”

What Woods hasn’t been able to do is figure out his faulty iron play. Distance control has been an issue, especially in the second round when he hit several approaches over the green. He’s found places this week at Augusta National that he’s never previously visited.

As a result, he hasn’t given himself many makeable birdie putts, the strain on his putter leaving him mostly in a defensive posture. Woods called his iron play “scratchy this week” — lthough he finally hit the 12th green on Saturday after finding Rae’s Creek the first two days.

“I just haven’t gotten it done,” Woods said. “I feel like I’m driving it better than I have all year, but I’m not capitalizing on it. And when I did miss, I missed in the wrong spots. My swing’s just off with my irons just at the wrong time.”

As a result, he also has failed to take advantage of the four pars at Augusta National, the holes he’s eaten up in his 20 previous visits. Woods had entered this week a cumulative 150 under on the par 5s, but he’s just 1 under on those holes through three rounds.

Mickelson hitting from no-man’s land

“I’m hitting so many good putts; they’re just not going in,” Woods said. “But I’m not hitting it close enough. I’m not getting up there and not taking advantage of the par 5s. Consequently, a good round is even par.”

As for Mickelson, his week was summed up by his second shot on the opening hole Saturday. After his tee shot sailed into the trees down the right side, his ball rested on the pine straw. He tried to hit from under some branches but failed to connect on his first swing.

“I hit the trunk on the downswing and just whiffed it,” Mickelson explained. “And punched out and made triple. I’ve made a lot of triples lately.”

In fact, he’s suffered a triple bogey in each of the last two rounds — it’s the sixth time in any major he’s had two triples in a week. Three of those have been at the Masters (2012, 2014 and this week).

A bogey on the ensuing hole had Mickelson reeling, but he managed to shoot 2 under for the final 16 holes. In the process, he picked up a few tips on the course.

“It’s Augusta; you always learn some things,” Mickelson said. “I was taking some notes — there were some new pins there. So I’m kind of doing preparation for next year, I guess.”

At least Mickelson won’t go away empty-handed this week. Thanks to his eagle at the par-5 eighth — set up by a driver off the deck to 9 feet — he is assured of a pair of crystal glasses awarded for any eagle at the Masters.

“Every now and then I’ll hit a shot like that and it makes it fun,” Mickelson said of his second shot. “The nice thing is I’ll get some crystal out of it. It wasn’t a total loss.”
