Stuart Appleby shot the fifth 59 in a PGA Tour event on Sunday at the Greenbrier Classic.

Every week of the 2010 PGA Tour season, the editorial staff of the SI Golf Group will conduct an e-mail roundtable. Check in on Mondays for the unfiltered opinions of our writers and editors and join the conversation in the comments section below.

APPLEBY'S 59 VS. TSENG'S THIRD MAJOR: WHICH IS BIGGER?
Cameron Morfit, senior writer, Golf Magazine: As Stuart Appleby might put it, whew. We have a lot of news to get to. On the women's side Sunday, Yani Tseng won her third major and her second this year with a one-shot victory over Australian Katherine Hull at the Women's British Open. That seemed big. Then on CBS, where Yanni does the theme music, Appleby shot the second 59 of the 2010 season and the fifth in PGA Tour history to win the Greenbrier by one over Jeff Overton. Which is the more impressive accomplishment, and which of the two feats do you care more about?

Jim Herre, managing editor, SI Golf Group: I care more about Appleby's 59 and one-shot win, but two majors in a season? That's clearly more impressive, and important.

Gary Van Sickle, senior writer, Sports Illustrated: I'm with Jim. I thought Appleby's round and win were captivating. But it was one of those magical one-day things on a course where scores were low, low, low. You can't compare that to winning two women's majors in a season. Tseng's is a career achievement that indicates she may ultimately be the player to beat in women's golf.

Mark Godich, senior editor, Sports Illustrated: I'll go with the two majors (and three at such a young age). Not to take anything away from Appleby's 59, but par seemed to be about 66 for the week. Appleby has to be more excited about the victory.

David Dusek, deputy editor, Golf.com: Both wins are historically significant and impressive. To shoot a 59 is nuts, but it's even more amazing that he did it to claim a one-shot win and earn himself a spot in the PGA Championship (and Kapalua and Augusta). That said, a second major in a season, on a course like Royal Birkdale, may top it.

Alan Shipnuck, senior writer, Sports Illustrated: Birkdale is a big-time course and Tseng has now made it clear that she's going to be a monster for the next decade. Big picture, this was the most important win. But it was impossible not to get swept away by what Apples was doing. His magic round is an all-time stunner.

Damon Hack, senior writer, Sports Illustrated: I'm going with Yani. Three majors by the age of 21, and one win shy of a career grand slam. Nobody male or female has done so much so soon in the history of the game.

Farrell Evans, writer-reporter, Sports Illustrated: I care more about what Appleby's 59 represents for the game. I'm not saying there's anything wrong with birdies, but par should mean something more than just once a year at the U.S. Open.

Shipnuck: Back in Geiberger's day a 450-yard par-4 was a monster. Now it's a driver/flip wedge. With soft conditions and little rough, a Tour course needs to be 8,500 yards or more to have teeth. Seriously.

Van Sickle: There's a lot to like about Appleby's win. Now he's in this week at Akron (he had previously committed to the event at Turning Stone) and also in the PGA Championship. Nice upgrade.

Godich: Don't forget that two-year free pass. Not bad for a guy who had to use a career exemption to get into fields this year.

Herre: I bet Appleby was just as excited to see so many putts go down. He's the classic Aussie — ball-striking genius, not so hot on the greens.

Dusek: Appleby should also be licking his chops about getting to play Kapalua again. He won the season-opening event there in 2004, '05 and '06.

IS THE GREENBRIER TOO EASY FOR THE TOUR?
Morfit: There were loads of low scores at the Greenbrier, where during one round Overton reportedly hit wedge into every hole but one (excepting the par-3s, I assume). Was this a Tour-worthy golf course?

Herre: Greenbrier looked like a course anyone would love to play, but maybe not a great test for the pros. Although the low scoring made for a fun show, and the Tour is show business, right?

Van Sickle: Was Greenbrier exciting TV every day it was on? Absolutely. No one is going to say, "Scores were too low — that sucked." They'll be saying, "Wow, did you see all those birdies and eagles and guys with chances to shoot 59?" Nothing wrong with having an easy, low-scoring week on the PGA Tour. Variety is good.

Hack: I don't mind the occasional birdie-fest to liven up the summer. Plus, if it was good enough for Sam Snead ...
