James Adducci, who took home $1.19 million on a bet when Tiger Woods won the Masters, is again putting his faith in the 15-time major champion.

Adducci took $100,000 of his winnings and placed it on Woods to take the title at all four majors this season, according to Golf Digest, which confirmed the bet through sports book operator William Hill U.S. Adducci placed the bet at SLS Casino in Las Vegas, the same sportsbook where he gambled $85,000 on Woods to win the Masters at 14-to-1 odds.

Adducci, a 39-year-old from Wisconsin, is getting 100-to-1 odds on Woods winning the Grand Slam, which would pay out $10 million.

The second leg of the Grand Slam, the PGA Championship, will be held next week at the Bethpage Black course in Farmingdale, N.Y., with the U.S. Open in June and the British Open in July. Woods is the betting favorite for the PGA Championship at 8-1, according to Westgate Sportsbook.

No golfer has ever won all four modern majors in the same season, although Woods held all four titles at the same time over the 2000 and 2001 seasons. The term Grand Slam was coined in 1930, when Bobby Jones won the British Open, U.S. Open, U.S. Amateur and British Amateur.
