Matt Kuchar, William McGirt and Gary Woodland share the 54-hole lead at the Memorial Tournament, but several big names are lurking. Here's what You Oughta Know heading into the final round at Muirfield Village.
• This is Kuchar's sixth lead/co-lead after 54 holes. He's converted two of the previous five into wins. The 2013 winner is 68 under in this event since 2009. That's 35 strokes better than Dustin Johnson.
• McGirt is seeking his first win in his 165th start, and that could be good news – the last two champions at Muirfield Village (David Lingmerth and Hideki Matsuyama) were first-time winners.
