Matt Wallace enjoyed double delight in the 100th US PGA Championship after reaping the rewards of a change in attitude.

Manchester United fan Wallace carded a second round of 66 to make his first halfway cut in a major and finished early enough to then watch his side beat Leicester City 2-1 on the opening day of the Premier League season.

The 28-year-old has won twice on the European Tour this season but had missed the cut in his last four starts before starting to work with psychologist Lee Crombleholme.

"The greens were really nice this morning, perfect conditions," the Moor Park-attached professional said. "I played as nice as yesterday and am slowly getting into this rhythm that I've been working on with Lee, to be patient and not be too downbeat about shots that don't come off.

"After the Open I wanted to do something different, just change the way I thought on the golf course and he's been brilliant so far. We're slowly getting back to where we want to be."

This year's Hero Indian Open and BMW International Open champion continued: "I wasn't enjoying my golf, strangely. People might think you've won twice this year and should be loving it but it's fickle this game. I felt like I was swinging it better and playing better but I was scoring worse.

"It was difficult to get my head round why and I didn't want to keep going in the same direction. It was important to catch it early and this is definitely what I needed.

"One over yesterday was a step in the right direction even though it wasn't the score I wanted. I haven't made a cut in the majors, this is my first one so I'm very happy with that. It's definitely a step forward and I'm going to go and hopefully watch [Manchester] United win now."

Wallace was lying in a tie for 23rd place on three-under par when play in the second round was suspended, and later abandoned, mid-way through the afternoon due to thunderstorms.

It is due to resume at 7am local time today with leader Gary Woodland in the club house on 10-under, one shot clear of fellow American Kevin Kisner.

Starting his second round from the 10th, Wallace made a flying start with birdies in three of his first five holes before he picked up another shot at the 18th to go 'out' in a four-under score of 31.

The only blemish on his scorecard was to come with a bogey fifth at the four, but a two at the sixth moved him back to three-under and into the final two rounds for the first time in his fourth appearance at a major.
