Sergio Garcia, who came from four down to beat Ryder Cup team-mate Padraig Harrington in the quarter-finals, staged another recovery act at Wentworth today.
After losing three of the first six holes to New Zealander Michael Campbell, the 22-year-old Spaniard clawed his way back to all square at lunch.
He was round in a six-under-par 66 to Campbell's 67.
In the other semi-final - also delayed for 30 minutes by early-morning frost - Open champion Ernie Els was four up after five on Fiji's Vijay Singh, but only two ahead after 16 holes.
