"I feel like I'm due for a good ball-hitting day". The Official World Golf Ranking is the tiebreaker. By hitting the mesh fence, it rolled up and snagged the ball, which eventually spit out of the fence and this time landed out-of-bounds.
The double-bogey included a freakish attempted recovery shot, with the left-handed Mickelson switching to a right-handed stance in a failed attempt to play his way out of trouble when his tee-shot ended up nestled against a fence alongside the left fairway.
Englishman Tommy Fleetwood (66) and former major victor Keegan Bradley (68) share the 36-hole lead at nine under - four strokes ahead of a five-way tie for third including reigning British Open champion Francesco Molinari.
Given the difficulty of thick rough and fast greens at Orlando's famed Bay Hill course, Leishman is confident he can claw his way back up the leaderboard with a hot second round on Friday.
The Englishman was mistake-free at Bay Hill and fired off five birdies, including two on the last four holes.

Bradley's first-round 67 put him one shot clear of several players tied for third at four under, including Phil Mickelson - who worked his way around a double-bogey at the 10th to shoot 68. "It just wasn't going to work out". "The wind's up, but it was a favourable condition today the way the wind was going".
He didn't think the first shot was all that hard, but he at least rallied with three birdies that left him three shots out of the lead.
Even with a four-shot advantage, Fleetwood and Bradley have to be concerned with more than themselves in the final group.
"Oh, man, those are two great guys", Watson said.
Hatton faced a tough chip after the missed iron shot, but he recovered to hit it foot from from the hole and salvaged a par.

Day told the PGA Tour that he had an MRI on Monday that revealed he has a tear in a disk in his lower back.
Off camera, you can hear Hatton's caddie say, "No".
"I was on a dose pack to try get the inflammation out of it, and that didn't get any better". He finished in sixth place in 2017. He had five top-15 finishes in five starts this season.
The lone par during the birdie run was enough for some of Sloan's Canadian supporters to get after him for not being a Maple Leafs fan.
"That's typical Leafs fans, they're bitter because their team never pulls it out so I can understand that", Sloan quipped.
