Michael Sims did something yesterday that he's rarely achieved all season – completed a round of golf without a single bogey.

But even better than that, he dotted his scorecard with five birdies, shooting the second lowest round of the day at the Nationwide Tour's final regular event of the season, the Miccosukee Championship in Miami

His bogey-free 66 on the 7,200-yard, par 71 Miccosukee Golf and Country Club meant that he's now gone 25 holes without dropping a shot, after finishing Thursday's opening round with three birdies on his back nine.

It was a round bettered only by former PGA Tour star Esteban Toledo who recorded a six-under 65.

Sims and Toledo started the second round in a tie for 69th in a field of 144 and made the biggest moves of the day.

Just three strokes behind joint leaders Won Joon Lee and Josh Broadaway and in a tie for 12th at the end of the second round, the enigmatic Sims has given himself a real chance of automatically retaining his Nationwide Tour card and earning a place in next week's Tour Championship which features the top 60 money-earners.

But with $650,000 up for grabs this weekend, and $112,500 of that going to the winner, Sims will know he has to continue his sparkling form throughout today and tomorrow.

Having started the week in 65th place on the moneylist, he'll more than likely have to secure a top 20 finish tomorrow in order to achieve his goal.

Otherwise, it will be back to PGA Tour School next month.

However, his confidence will be high as yesterday he showed the kind of consistency that has eluded him for most of the season.

Too often in the last nine months his string of birdies have been offset by double bogeys.

No such blemishes appeared on the scorecard yesterday as he picked up shots at five par-four holes – the third, seventh, ninth, 12th and 13th.

Strangely, he could only make par at the course's three par-fives, holes on which he normally excells. In fact, he's ranked first on the Tour for the number of eagles collected this season – 19 in total.

At the start of yesterday's round, the 30-year-old Bermudian was in danger of missing the cut.

Now he will be focused on eliminating any mistakes today and putting himself in position to make a final round charge – a round that could ultimately determine his future.

Next week's Tour finale, at Daniel Island Club in Charleston, South Carolina, will offer a million dollars in prize-money and will decide the Tour's top 25 for the season, all of whom will advance to the lucrative PGA Tour which features the world's top players almost every week of the year.
