When did Wes shoot 290? I know he shot 290 the hard way a few years ago during match play (11-in-a-row, then a foul). There are a lot of 280+ games that no one really keeps track of. Even the 290+ games are hard to find references to. Steve Jaros shot 300 on TV, then a 290, a 569, and an 814 to round out USBC Masters a few years ago.
I believe WRW has a 290+ game, as does Mark Roth (I saw that one on ESPN Classic a while back). Johnny Petraglia has at least a 298 and a 300 that I can think of.
If there's a definitive answer, I'll go out on a limb and say it's someone like PDW, WRW, or Duke, but only because they have so many shows under their belt and have been successful for so long.
