Viktor Hovland holds a two-shot lead at the half-way point of the Arnold Palmer Invitational after Rory McIlroy endured a disappointing finish.

Overnight leader McIlroy was not as sharp as he was on the opening day at Bay Hill but still looked in with a chance of retaining his status as pacesetter for much of the round.

That was until the 15th, when he needed three putts from 30 feet. He then missed a birdie opportunity on 16 and failed to save par from eight feet on 17.

The Northern Irishman ultimately finished at level par for the day with 72 – Hovland, who started on the 10th, carded 66, giving him the round of the day and the lead.

His score would have been even better had he not bogeyed the 13th, however he responded admirably to that set-back with three birdies in his next four holes.

Hovland added two more on the fourth and sixth to ultimately set the clubhouse lead as he moved to nine under for the tournament – McIlroy failed to rise to his challenge.

Joining McIlroy two shots back on seven under in a tie for second are Talor Gooch and Tyrrell Hatton, the latter of whom felt his four-under 68 was "pretty flattering".

Similarly, Hovland is not getting carried away with his position in the standings, particularly considering he was only two shots off the lead heading in the weekend last year and went on to finish 15 off the pace.

"I kind of try to forget the weekend here last year," Hovland told the PGA Tour. "I played really well the first few days, very similar to how I played so far this year.

"The course just gets harder and harder every single day, and it started blowing. A few too many bad swings and I ended up in bad spots and just didn't really take my medicine."

As for McIlroy, the four-time major champion was taken aback by how quickly conditions on the course changed from Thursday, adamant he will be better prepared on day three.

"Those are the sort of greens you expect to see late on a Sunday, not late on a Friday," McIlroy added. "It's going to be interesting to see where they go from here, but it's going to be a good test over the weekend.

"I'm glad I got 18 holes in those conditions because the course definitely changed a lot from when I played it yesterday morning to this afternoon. I'll be a little more prepared for it [on Saturday]."

Billy Horschel is one shot further back on six under, and then there's a three-shot gap to a group of seven – world number one Jon Rahm is at two under.

Patrick Reed, Henrik Stenson and Justin Rose were among those to miss the cut, which was set at three over par.
