Louis Oosthuizen is closing in on a career Grand Slam of sorts.
One he'd rather not have.
For the third time in his career — and second time in a month — the South African was runner-up in a major championship. This time, it's the British Open, where he lost to Zach Johnson in a playoff Monday evening.
Australian Marc Leishman also got in the four-hole playoff. A bogey at No. 1 essentially ended his chances.
Oosthuizen took it right to the end, misreading putts on the final two holes — one from 5 feet, the other from 12 — that could have forced sudden death with Johnson.
Oosthuizen has now finished second in every major except the PGA Championship, to go with a British Open win in 2010.
