A son of Spirit Of Boom, Booming Lad then went down in a close finish when second to Missile Thunder in a 1000 metre Open Handicap at Townsville on May 27.
Simmons has booked apprentice Gabrielle Semmens for Booming Lad who has a good record at Mackay with two wins and three seconds from five starts.
He also is a two-time winner from four starts over the 1100 metre trip at the Ooralea track.
“I tried for Olivia Kendal as she ran second on him last start in Townsville, but she was unavailable, so I booked Gabrielle Semmens,” Simmons said.
