King Zephyr will be shooting for his fourth consecutive victory and fifth from six career starts when he runs in the William Newton VC Handicap (1400m) at Flemington on Friday.
Part-owned by former trainer Chris Hyland, who now works for Begg as one of the inform trainer's trusted lieutenants, King Zephyr was successful on debut at Bendigo in March last year before being given a break.
After one start in August last year, King Zephyr was again tipped out before making it three wins in succession this campaign with a win at Pakenham and two at Sandown.
King Zephyr steps up in both class and distance on Friday, but it is a race that Begg had earmarked for the gelding after his most recent win at Sandown.
"We've taken each step with him as it's come," Begg said.
"We've tried to keep him in his lane, pick off the right races as they come and we're happy just taking the small steps at this stage.
"He's got to a benchmark 78 on Friday and he comes back a little in weight. He had 61 kilos the other day and comes back 59-½ on Friday."
Since scoring at Sandown on March 26, King Zephyr has finished third in a 1000m jump-out at Cranbourne on April 14.
