Wiesberger retains his stranglehold at the top in Shenzhen

Gregory Bourdy celebrates his hole-in-one at the third.

AMERICAN pair Bud Cauley and Tony Finau share the lead at the halfway point of the Valero Texas Open.

Both men are tied on eight under as Cauley, who is chasing a first PGA Tour win, fired a six-under-par 66 while Finau went one better with a 65.

Cauley struck six birdies in his blemish- free round but Finau’s card was more erratic, with an eagle, eight birdies and three bogeys keeping the scorers busy.

Australian Cameron Smith, who matched Finau’s 65 as the lowest score of the day, Bob Estes and Kevin Chappell lead the chasing pack on seven under.

Scotland’s Martin Laird is three shots off the lead after his 67 moved him to five under but Graeme McDowell shot a twoover-par 74 to fall back to six off the lead.
