The favored team in Las Vegas won 25 of the last 26 games in the round of 64, including 15 of 16 on Friday. The run began Thursday with favored Xavier's win overOle Missand kept going until underdog Daytongrinded past Providencein Friday's nightcap.
Favorites were winning, but they weren't always covering the spread. Underdogs went 8-8 against the spread Friday and were 20-12 against the spread over the first two full days of the tournament.
Thursday was huge. One sportsbook said Thursday was its biggest single-day win in memory.
"Epic day, absolutely," Jay Rood, vice president of MGM race and sports, said of Thursday. "Tough day for the players coupled with the fact the books did well Wednesday, too."
"Yesterday was amazing," Dave Pemberton, director of specialty games for Caesars Entertainment, added Friday night.
Including the First Four games Tuesday and Wednesday, underdogs covered the spread in the first 10 games of the tournament. Favorites went 4-12 against the spread Thursday. No. 14 seeds Georgia State and UABpulled off upsets as double-digit underdogs, damaging brackets and destroying money-line parlays everywhere.
"We didn't sweep the board [Thursday] but we were pretty close," Jason Simbal of CG Technology's sportsbook said.
The betting public isn't at its most sophisticated in March, when spring break collides with the NCAA tournament in Las Vegas. The public normally fancies the favorites and parlays at long odds. When underdogs go on runs, like they did Thursday, the books win big.
Even No. 16 seed Hampton, the largest NCAA tournament underdog in 16 years, had believers in Las Vegas. William Hill accepted 260 money-line bets on Hampton upsetting No. 1 Kentuckyat 150-1 odds. That money will be staying in Vegas.
Kentucky cruised to a 79-56 victory but did not cover the 35-point spread. The line was the largest in an NCAA tournament game since Duke was a 47-point favorite over Florida A&M in the first round of the 1999 tournament.
The majority of money-line bets on Hampton were for $5 or less. The largest was a $314 bet that would have paid $47,100. In total, $2,240 was risked on Hampton beating Kentucky, according to William Hill. Eight people bet on Kentucky on the money line, laying monster odds of minus-50,000 (1-500). The largest money-line bet on the Wildcats was $600 and paid $1.20.
