Call it spring fever but the midweek victory from untapped four-year-old Terravista has prompted a bold declaration from his jockey and a physical reaction from his trainer.

Having his first race ride on Terravista in Wednesday's THINC Handicap (1000m) on the Kensington track, Hugh Bowman was an instant fan.

"He gave me the best feel of a horse I've ridden at a midweek meeting for quite some time," Bowman said.

"I didn't expect to be so close but he was right up there and travelling beautifully underneath me.

"The best bit was when I asked him to stretch out he found again."

Bowman's words echoed the sentiment of Terravista's trainer Joe Pride.

A half-brother to Pride's good sprinter Tiger Tees, Terravista was having just his third start and first since recovering from stress fractures which ended his first preparation.

Pride watched the win from a television monitor near the Theatre Of The Horse and was bubbling with excitement after it.

"I've got goosebumps," Pride said.

"He's pretty special.

"That's what good horses do when they resume and he's come back in really good order. There is a lot of improvement in him and I'm excited by the win."

In what is set to prove a strong meeting, an equally impressive performance was delivered a race later by Polarmore.

By More Than Ready out of Golden Slipper winner Polar Success, Polarmore settled midfield and wide in the Peters Meats Handicap (1150m) before dashing home to record a smart 33.72s for his final 600m.

O'Shea is hoping to use the spring to season the colt before turning his attention to some bigger autumn targets.

"I think he needs some miles under his belt," O'Shea said.

"He's still got to learn his trade and it's no use getting to the autumn wanting to run in good grade if he's only had two starts."

Jockey James McDonald was also blown away by the victory.

"That was outstanding. He came up the rise just smoking."
