The world's best golfers, including seven of the top 10, have converged for the Memorial Tournament, running through Sunday at Muirfield Village Golf Club in Dublin.

As it usually is, the event known as the Masters of the Midwest is up for grabs.

Over the years, Memorial winners have come from Australia, Fiji, Sweden, South Africa and the United States. Some are old masters like Tom Watson in 1996, while others are stars on the rise. A young Tiger Woods won three straight starting in 1999.

This 120-player field starts official rounds Thursday. Here are a few golfers to watch.

Tiger Woods

Official World Golf Ranking: 1

That his season is considered lackluster shows only how good he really is. Woods has retained the No. 1 world ranking, finishing in the top 10 in five of six starts. His win at the Arnold Palmer Invitational March 29 and strong showing at the Masters indicate he's ready to compete. If he can regain his late-surge prowess, he could become the first player to win the Memorial four times.

Kenny Perry

Official World Golf Ranking: 7

With the course's similarities to Augusta National, you might expect 2009 Masters winner Angel Cabrera to be a favorite next week. In reality, Perry, one of two players Cabrera defeated in a playoff, is more likely to shine. Perry is a three-time Memorial winner (1991, 2003, 2008) and has been on fire this year. He has lowered his season scoring average below 70 and has finished in the top 10 six times in 13 starts.

Geoff Ogilvy

Official World Golf Ranking: 5

Through 11 events in 2009, Ogilvy has claimed two difficult championships: the Mercedes-Benz Jan. 11 and the Accenture Match Play March 1. He sits No. 3 in the FedEx Cup, a good barometer of consistent play in various tournaments. He ranks fourth in both birdie average and putting average - two skills that will translate well at Muirfield.
