Mike Weir was born on 12th May 1970 Sarnia, Ontario, Canada.
He plays golf left-handed.
Mike wrote the famous letter to Jack Nicklaus when he was 14 asking him if he should play left or right handed.
Jack replied and told him to "do what feels natural".
Less than 10 years later he was the first Canadian to win a Major Championship, the 2003 Masters Tournament.
