Which golfer became the first European to win the Masters in 1980?

Seve Ballesteros became the first European to win the Masters in 1980.

At age 23, the Spaniard won the 44th Masters Tournament at Augusta National Golf Club from April 10–13. Ballesteros opened with a 66 and held a seven-stroke lead after 54 holes. Trouble at Amen Corner on Sunday briefly reduced his advantage, but he steadied himself with a birdie at the 15th hole and finished with a 72.

His four-round total of 275 was 13 under par, four strokes ahead of Jack Newton and Gibby Gilbert. The victory was Ballesteros’s second major championship, following his 1979 Open Championship triumph. He later won a second green jacket at Augusta in 1983.

The question refers to the first European winner, not the first international winner of any kind. Ballesteros’s achievement helped establish a new era of European influence in major golf. His 1980 Masters record as the youngest champion lasted until Tiger Woods won at age 21 in 1997.
