Woodrow Wilson coach Ron Kidd revealed Fortune shot 74 percent in the regular season.
"I approach them the same every time I go to the line. I know I'm going to make them," Fortune said.
Martinsburg's Isaac Thornton struggled to maintain a strong handle on the ball as he dribbled up the right side and fired an airball from beyond the 3-point line that was rebounded by Woodrow Wilson in the final seconds.
"We were kind of hoping to go to the basket. Maybe I should've called a timeout," Martinsburg coach Dave Rogers said. "That's one of those calls you look back on and it will probably haunt you forever."
The Bulldogs (20-5) led by as many as four and went ahead 50-47 with 1:47 remaining on Brandon Cato's two free throws.
From there, Martinsburg's Michael Cole stole an inbounds pass, but Cato's cross-court pass was intercepted by Isiah Walton, who went in for a layup to cut the lead to one with 54 seconds left.
Cole was fouled with 30.8 seconds left, but missed the front end of a 1-and-1, leading to Fortune's free throws.
Free-throw shooting in the fourth quarter has been a problem all year for the Bulldogs.
"We've not been a good foul-shooting team," Rogers said. "I think as a team we were 60 percent. That's been our Achilles' heel at times."
An 8-for-18 performance from the line in the fourth wuarter nearly cost the Bulldogs in the Region II final against Musselman, which Martinsburg won 49-47. The Bulldogs were 4 of 11 overall from the line on Thursday.
"We played good defensively. We came up short," Brandon Cato said.
Thornton led all scorers with 14 points and added six rebounds and four assists for Martinsburg. Tevin Walker scored nine, Cameron Cato and Kirk Hairston each had eight and Brandon Cato added seven. Hairston also grabbed six rebounds in only 10 minutes.
Travis Parkulo had 13 points and 12 rebounds for Woodrow Wilson (17-7).
"I don't think there's any question out of all four (top seeds) we got the toughest draw," Rogers said. "They've got athletes, they've got plays, they've got a rich tradition. You're always in for a fight when you play (them)."
Fortune finished with 11 points, five more than his season average. His 3-pointer with 2:45 left gave the Flying Eagles a 47-46 lead, but Thornton responded with a jumper to put Martinsburg back in front.
Martinsburg led 17-16 after the first quarter and 27-25 at halftime, but trailed by one after the third.
Damien Tunstalle had 11 points and eight rebounds for Woodrow Wilson, scoring seven straight in the third quarter to make it 41-38. He also guarded Thornton on the final possession of a game that featured seven ties and 13 lead changes.
"I was trying to keep him in front of me. I saw he was a little off with his dribble, dribbling it off his knee and stuff. I was just trying to contain him."
