Tenacious and lightly raced galloper Blue Grotto chases three straight victories as he looks to build on his impressive record at Moruya on Sunday.

The name is a racing institution on the Northern Rivers and for the McGurens - Samantha and Matthew - who met as brilliant young apprentice riders, their first city starter, outsider Fortyfive Parklane ($41 on TAB) is likely an endurance test for Matt into a TAB Highway at Rosehill Gardens on Saturday.

Brave Maso is expected to firm sharply from her $4.60 on TAB for Friday's Moruya race meeting following an impressive first-up victory at the course on June 21.
