Bubba wants his jacket back

Bubba Watson is on course to regain the Masters title after a second round 68 moved him clear of the field.

Watson is aiming for his second green jacket in three years, boosted by five straight birdies from the 12th hole on Friday.

"I'm trying to get the jacket back," Watson said. "I want that feeling again.

Even after making just his second bogey of the tournament by missing a short putt at the 18th, Watson walked off with his second straight round in the 60s and a 36-hole score of 137.

"It's not science here," Watson said. "It's try to hit the greens, and if you're hitting the greens that means you're obviously hitting your tee shots well. So that's all I'm trying to do, just hit the greens."

Watson finished in a tie for 50th last year as the defending Masters champion, his worst showing in five previous appearances.

The 35-year-old American much prefers to come in under the radar.

"I could enjoy the Champions Dinner this time and listen to the stories. I was in awe when I was the champion, when it was my dinner," Watson said. "I didn't know how to handle it the best way, so I didn't play my best golf last year."

As for his birdie streak, Watson added: "You're so focused on what you are doing, you are not really thinking you have just had three in a row, four in a row," Watson said.

"It's one of those things. Everyone has had that stretch before, playing with their buddies or playing in a tournament, so it's not that big a deal when we think about it.

"But at the Masters, it makes it a big deal."

Looking ahead to his chances over the weekend, Watson added: "I've been lucky enough to win here. Just got to keep my head down, same thing I've been doing the last two days, try to stay level, not too energized, not too excited."
