It really depends on the sport. If you take football or something similar, it makes virtually no difference.
But if you take Fencing for example, it would be a much larger disadvantage to fence with your 'off' hand than with your 'main' hand.
One disadvantage with leftie golfers is that they all need special Golf clubs which are often more expensive.
However in say Baseball, being a left handed pitcher or batter, can give you a large advantage over someone who is right-handed.
The answer depends on which way the athlete rotates- if he is left handed, then the discus will spin counterclockwise. It will spin this way because the athlete must flick his wrist and spin the disc off his fingers when he releases the disc. If the athlete is right handed, then the disc will rotate clockwise for the same reason.
The biographies give no clue, but there are signs he might have been left-handed.
