Neither of them had their finest hour but Woods loss ratio (21 from 37) is significantly worse than Mickelson (22 from 47) and more might be expected of Tiger as he is clearly the greater individual player.
what are their respective rates in the singles?
For me, that's the only record that show's how they preform at the event.
Mr Ryder Cup himself wouldn't have won a point paired with Mickelson this week.....
