CHARLOTTE, N.C., May 4 (UPI) -- Tiger Woods, Arron Oberholser and Vijay Singh are tied for the lead after two rounds of the PGA's Wachovia Championship at Charlotte, N.C.

The three are 6-under-par 138 through 36 holes.

Woods shot 4-under 68, Oberholser shot his second straight 3-under 69 and Singh came in with a 1-under 71 Friday.

"I got off to a pretty good start this morning, Woods said."(But) I felt like I pretty much have maximized my rounds."

"I couldn't get the greens this morning, I don't know why," Singh said.

Ted Purdy (69) and Jason Bohn (72) are tied for fourth place at 5-under 139.

First-round leader Padraig Harrington (75) is tied with a large group including Phil Mickelson (71) at 3-under 141.

A bogey-triple bogey ending cost Harrington a shot at the leaders.

Luke Donald (148) and Jim Furyk (150) were among those who missed the cut.
