Charl Schwartzel: Back in contention after second-round 68
Charl Schwartzel has urged Open Championship organisers to prevent conditions at Muirfield becoming a "lottery" over the weekend.
The South African opened with a 75 and let his frustration boil over when he slammed his eight iron into the rock-hard ground, snapping the shaft in the process.
But he took advantage of an early second-round tee-time to battle back into contention with an excellent four-birdie 68 that hauled him into the top 20 on one over par.
"Given that I'm going to be climbing up the leaderboard I hope they will water the course on Saturday morning," Schwartzel joked. "I don't like it when it starts becoming that much luck, because that's what it is.
"When it gets this crusty and you're working on balls bouncing....with six-irons going at 280 yards, but they're bouncing at 210. How do you judge that? It becomes a bit of a lottery.

"You don't know what's going to happen and you need to be able to play like we played today. That way, you can still control your golf ball and quality shots get rewarded.
"But when it gets to the afternoon, you can hit good shots and you're going to get all sorts of results. It's not exactly fair in my eyes, but if I win, I'll be kissing this golf course."
Schwartzel revealed that a change of putter paid handsome dividends in his second round as he cruised to the turn in 33 and added a fourth birdie at 14 before making his only mistake of the day at the 16th.
"I changed the putter and it really gave me some confidence," added the 2011 Masters champion. "It's the same style of putter but with one of those long grips, a bit more weight. And it made quite a bit of a difference."
He was also forced to put a new eight iron in his bag after losing his temper on Thursday, and he admitted: "It was just an instant thing. I didn't think what I was doing. I'm not really proud of it.
"When you're playing under so much pressure, and you're expecting so much of yourself, it's just a reaction that just comes.
"I've done it a few times in my career, but never, ever broken a club that way. So it just shows you how hard the ground is, the vibration that obviously went through it."
