An imported galloper, Light Infantry Man had been struggling for form until winning during Melbourne Cup week at Flemington before striking Group 1 form at Ascot in Perth in December.
Brown now has eight Group 1 winners to his credit of which seven have been supplied by Maher, including his first aboard Snapdancer in Adelaide back in 2022.
He said the partnership he has formed with Maher means a lot.
"I do go on about it a lot, but I just continue to get good support from Ciaron and this ownership group," Brown said.
"They really have batted for me in the last six-to-12 months and put me on their good horses and it's just so rewarding to deliver them results."
Brown said he was expecting a stronger tempo on Saturday, but the race worked out perfectly.
"It was sedate early but, as Jenni does, she picked it up a long way out," Brown said.
"He was always going to relish it this bloke. The 2000 metres was never a worry for him, but all the cards fell our way today.
"It's a long straight that Flemington straight, but he really appreciates being ridden like that and I'm super rapt to get the job done today."
Craig Newitt, who partnered Pride Of Jenni, described the mare's performance as a 'bit of a head-scratcher'.
"She flew the gates, and I was happy with the first couple of furlongs, and she had travelled well, and we got to the 1200 (metres) and they were still there," Newitt said.
"I let her slide a little bit, but she was well and truly beaten at the thousand which was very unlike her."
