Dimitri Mascarenhas guided Hampshire to their second Friends Life t20 title in three years despite twice tearing a shoulder muscle in the past fortnight.
The 34-year-old skipper revealed he had to play through the pain as his side fended off a late Yorkshire charge to secure a 10-run win at the SWALEC Stadium in Cardiff on Saturday night.
He said: "I've torn my lat tendon. I tore it two weeks ago and then I tore it again last week when I tried to play Pro 40. I had a scan and it's torn so I had to grin and bear it today. It was a huge stress to be honest. It's not one of those where you can have an injection."
He added: "We were trying to sort out team selection if I didn't play and for the team balance. It's not easy when your captain is looking like he's not going to be fit. I was lucky enough to get through."
Hampshire had begun the day as the bookies' outside chance to win and, after his own problems beforehand, Mascarenhas admitted his own delight.
"Personally for me - it's the best one by far," he said. "I missed the first win two years ago because I was injured. To win two games today and captain a young and inexperienced side was a great thrill and one I'll remember for a long time."
David Miller almost single-handedly stole away victory, with a breathless 72 from 46 balls, but Mascarenhas and his young attack held their nerve to defend their 150 for six on a slow wicket.
Mascarenhas, who had been unable to bat due to the problem, set his side towards victory with a superb new-ball spell of two for 20 before 22-year-old seamer Chris Wood stopped a rampant Miller from scoring the 14 he needed from the final over.
Yorkshire skipper Andrew Gale was full of praise for Miller's efforts, hailing the South African's brutal hitting, which saw him clear the ropes five times, for taking the Tykes within sight of an unlikely victory on their first ever finals day.
He said: "When we were 40-odd for four I thought someone had to play very well to get us in a position to win and David played out of his skin. Going into the last over I was backing us. Unfortunately it didn't go our way but fair play to David for getting us in a position to win that game because we were dead and buried."
