"The scratchers were calling out to me," Harrington said.
The player selected a Diamond Bonus Crossword ticket.
"I scratched it, and I thought I'd won maybe $200 or so," he recalled.
A closer examination revealed Harrington had scored the $300,000 top prize. He previously visited lottery headquarters in July 2020 to collect a $125,000 jackpot from a Pick 4 drawing.
Harrington said he plans to invest his latest winnings.
