Raging Blizzard stormed home to land another electrifying victory at Sha Tin on Sunday, but the boom on Wunderbar was lowered again when the talented sprinter suffered his third straight defeat.

Master trainer John Size was left with mixed feelings after the Class Two Tai Tong Handicap (1,200m), claiming victory with the in-form Raging Blizzard while conceding he was mystified by Wunderbar’s flat fifth as the $1.8 favourite.

A strong tempo established by Full Credit, who ran the first 200m 0.67 seconds inside standard time, set the race up for Raging Blizzard to swoop from last with an inside run for Hugh Bowman.

In contrast, that hot speed appeared to contribute to Wunderbar’s flat performance as the raging favourite trailed Full Credit in running and was swamped late when beaten two-and-a-quarter lengths.

“I don’t know what to make of it just at the moment,” Size said of Wunderbar, who was also fifth behind Raging Blizzard last month as the $2.5 favourite.

“On face value it was disappointing, but we’ll get into the detail and see if that tells us anything. Let’s have a look at him at home and take it from there.”

Backing up his dominant win on his previous start, Raging Blizzard made ground along the inside rail in the straight before launching a powerful sprint at the 200m when Bowman took him one off the fence.

The Per Incanto gelding shot to the lead just before the 100m and held on late to beat Gorgeous Win by a neck, with Copartner Prance and Swift Ascend close behind in third and fourth respectively.

“He’s very genuine, he has a beautiful attitude toward racing, he enjoys being left alone early but he’s there for you when you need him and he’s got a good record together now,” Bowman said after Raging Blizzard improved his record to six wins from 13 starts.

“He’ll head up to Class One and he won’t be out of place there.”

While a Class One over 1,200m on February 9 looms as Raging Blizzard’s next option, feature sprints could be on his agenda in the near future, with his rating set to soar into the 100s after Sunday’s triumph.

“He’s never been racing this well,” Size said.

“There was pressure on and the tempo of the race suited him. He’s obviously done no work early and he got an inside run and saved a lot of energy. He was able to finish it off well.”

Raging Blizzard clinched a double for Size, with the 12-time champion trainer continuing his resurgence after a quiet start to the season.

Country Dancer claimed a last-gasp success in the opener, the Class Five Tsam Chuk Wan Handicap (1,200m), under Karis Teetan to make it two wins from his past three starts.

The Nicconi four-year-old justified $3.1 favouritism when he ran on strongly from eighth to beat Sterling Wongchoy by a nose.

Size boosted his tally of wins for the term to 18, lifting him to ninth in the trainers’ championship and eight behind title leader, Pierre Ng Pang-chi.

It could have been an even bigger day for Size, with the 70-year-old notching four thirds on Sunday with Bundle Of Charm, Sight Supreme, Magnificent Nine and Bundle Award.
