Rory McIlroy has spoken of the testing conditions at TPC San Antonio following the first round of the Texas Open.
The Northern Irishman carded four birdies in an even-par 72, but was left frustrated by "silly mistakes" that cost him the chance to go under on his opening round for the first time this year.
"I started well, but then I threw in a couple of those silly mistakes I was talking about trying to eliminate last week," The Independent quotes McIlroy as saying.
"I hit the ball OK, it was not my best, but it was tricky out there. If the wind starts to blow then it is a tough course.
"I am still to break par in a first round this year, so it would have been nice. It is a tough course to make a few birdies with the conditions like they were this morning. I will give it a go tomorrow and try and post a good score and get ready for the weekend."
