In part due to his relative youth at the time he won the 1978 WSoP bracelet (aged 28), Baldwin has the earliest Main Event victory of any poker player alive.

[5] He defeated a final table that included professional poker players Ken Smith, Jesse Alto, Buck Buchanan, WSOP bracelet winner Louis Sager Hunsucker Jr., and businessman Crandell Addington, whom Baldwin defeated in heads-up play.

When Baldwin won the 1978 World Series of Poker Main Event at age 28, he became the youngest winner in its history.

In 1979, he won the $10,000 Deuce to Seven Draw event again, earning his fourth and most recent bracelet at the WSOP.

[6] Baldwin also competed in the Super Bowl of Poker tournaments, organized by 1972 world champion Amarillo Slim.

In 2005, after the acquisition of Mandalay Resort Group by MGM Mirage, Baldwin became CEO and President of the announced Project City Center, while continuing his responsibilities as CEO of the Mirage Resorts subsidiary.
