Holmes would have been frustrated with his disappointing second-round 73 as he hit three balls into the water on the Blue Monster course.
However, no one was more frustrated than Rory Mcilroy on the second day of the tournament as the Ulsterman lost his cool on the eighth hole.
After sending his tee shot into the water, Mcilroy flung his three iron into the drink as well. As a result, Mcilroy is expected to be fined by the PGA Tour.
Despite his mental breakdown on the eighth hole, Mcilroy struck six birdies and four bogeys in a two-under 70, which leaves him eight shots behind Holmes.
The 32-year-old bounced back with a birdie after registering a six on the first. However, his comeback was short-lived as he found the water again at the third.
But, in an emerging pattern on the second day, Holmes clawed his way back with two birdies in three holes.
It was on 18 that Holmes hit his third ball into the water. Even though he ended up finishing with a double-bogey six, he still managed to maintain a two-shot lead at the end of the second round.
Ryan Moore is currently Holmes' closest competitor as he registered two birdies and one bogey on his way to cutting Holmes' four-shot lead in half.
Adam Scott surged up to third place following a solid four-under 68, which included six birdies.
