The 20-year-old also beat a round-high seven defenders, made three clean breaks and assisted a try to cap a fine solo performance among a good team display.
Saints assistant coach Alex King was full of praise for the young full-back.
"Tom works incredibly hard at his game," he commented post-match. "He's a natural athlete who's got pace to burn, but he also works at all the basics. He stays after training and does all his add-ons.”
