Gavin Smith will make a decision within the next 24 hours on the racing future of open class trotter Great Things Happen.

The seven-year-old Love You gelding was scratched from Friday night’s Summer Trotting FFA at Addington with a suspected broken splint bone.

At best, the injury will be screwed and Great Things Happen will just be out for the season.

But, there’s a 50/50 chance he will be retired.

“There’s a hairline fracture and I suspect it may have been there for a while,” Smith said.

“He had a hematoma on the inside of the leg a while back and while that cleared up, it resurfaced again so I had x-rays done.

“That showed the fracture and now we need to look at things a lot more closely and get some expert opinions.

“If it becomes an issue with the suspensory it may be terminal, or not worth bringing him back again if it’s likely to be a problem again.

“He’s been a great horse to us and he’s already been through a lot with various other issues.”

Smith would have started the week thinking he had live chances in three of the features at Friday night’s Premier meeting.

Great Things Happen would have been a short priced favourite for his event.

Smith still has high hopes for Alta Maestro in the Summer Cup and Step Up in the Breeders Stakes.

Smith has got the drive again on Alta Maestro with John Dunn opting for Henry Hubert.

Henry Hubert was in dazzling form in the spring with a six length romp at Ashburton in a 1.55.7 mile rate for 2400m, which was just a fraction outside The Dorchester’s track and national record.

The horse then went on to win the Sales Aged Classic at Kaikoura.

Henry Hubert was then out of luck in two races in strong company at the Cup meeting and was spelled.

He has won both of his trials at Rangiora in recent weeks beating the likes of Dream About Me, Ultimate Machete and Alta Orlando.

“That’s going to be an intriguing and very tactical race with the Dunns having five starters against the All Stars’ two.

“If Ultimate Machete got to the front he would be very hard to beat but I can’t see him getting there easily.

“Funatthebeach has done nothing wrong in recent months and Henry Hubert and Alta Maestro are also marching towards open class.

“Then you’ve got Sheriff coming back into form and Franco Cristiano back after being off the scene for two years.

“All the ingredients are there for a very exciting race.”

Like most, Smith will be wondering if the real Dream About Me and Elle Mac are going to show up this week.

If they do not, Step Up will be as good a chance as any in the Group One.

“It was just a sprint for home last time and she wasn’t really entitled to make up the ground that she did.

“Barrier five is a bit of an in between draw because you don’t really know if you’re going to be going forward or back though.”

The promising trotting filly Swiss Miss resumes at the start of the night off the back of a very good trial behind Sundees Son and Kings Landing at Rangiora last week.

But, she has been dealt a bad draw with one of the second line.

“Ironically she follows out her half-sister (Motu Great Sensation) who is a good beginner, but I’m still not quite happy with the way Swiss Miss is trotting.

“She’s very smart though and I’m looking forward to the Oaks and the other features later with her.”

Shecandance is probably just a place chance racing against the likes of Cast No Shadow and Chiller Bay.

Smith is having his first drive on Machs Mareta in the last event and says she can win with the right run.
