Harris took two horses to Riverina Paceway and won the first two races as Roll Out ($17.00) and Blaster Ranger ($1.22) claimed a race-to-race double to kick off the eight-race card.

Roll Out sprinted sharply and used the sprint late to down odds on favourite Rollecks ($1.95) and win the TAB 3YO Pace (1740m).

Carribean Blaster then led all the way to win the Hillis Motor Group C0 Pace (1740m).

Both horses recorded identical winning mile rates of 1:55.1.

Harris was pleased to see Roll Out break through for his first victory since winning three of his first four race starts.

"I couldn't believe he hadn't been able to win a race yet this season," Harris said.

"He's been running into one a bit better than him or not having much luck.

"He's a real professional."

Blaster Ranger made it two wins in a week for Grenfell owner Ted Baker after scoring at Wagga last Sunday.

"Blaster Ranger's not such a professional. He's not a great racehorse yet but he's learning," Harris said.

"He's got some ability, without getting carried away, and once he learns to settle down, he'll race a lot better."

Harris has elected against contesting further heats of the Breeders Challenge series and will most likely instead aim Blaster Ranger for the blue and regional finals.

Cameron Hart also enjoyed a driving double at Wagga on Friday with wins on Im Feeling Firey ($6.50) and Muscle Mach ($5.00).
