WHAT TO EXPECT: Moving day

Expect a lot of players to make their move in today's third round.

Several of the top players -- Tiger Woods, Phil Mickelson and Padraig Harrington, to name a few -- are more than five shots behind co-leaders Chad Campbell and Kenny Perry.

They'll want to shoot low scores today so they can get into Sunday's final pairing. Since 1990, all but one winner has come from the final twosome.

MEET THE ROOKIE: Ken Duke

The 40-year-old native of Arkansas is making his first Masters appearance. Duke, who had the best year of his PGA Tour career in 2008, shot rounds of 71 and 72 to make the cut.

Q: Were you thinking about the cut line?

A: Not really. I was just trying to shoot par. And I played good all day, just missed a short putt on 16. I pulled it.

Q: Tell us about the pin you're wearing.

A: My mom's recovering from breast cancer surgery. So that's for my mom. ... She's doing great.

Q: Is it a joy for your mom to see you play out here?

A: It's been a dream of mine for my whole career for her to be here. And so many people are up from Arkansas up here that've been pulling for me and rooting for me.

WHERE TO GO: Amen Corner

The 11th, 12th and 13th holes should be part of the critical action today, if history holds true.

The leaders will want to give thanks if they can get through the famous stretch of holes in even par or better.

The challengers will want to make pars on Nos. 11 and 12 and at least a birdie on the par-5 13th.

Herbert Warren Wind, the golf writer for Sports Illustrated , came up with the name for the trio of holes as he described the action at the 1958 Masters.

He took the name from a jazz recording, Shoutin' in That Amen Corner . Wind wrote that the album was recorded by Milton Mezzrow, but research has shown that Mezzrow did not make a record by that name.

Nevertheless, the nickname became part of the tournament's lore, and Masters patrons flock to the corner every year.
