McDowell slips back after disappointing 73

First round leader Graeme McDowell could only manage a one-over-par 73 in the second round of the Zurich Classic of New Orleans today, slipping to joint 11th.

The Irishman took the first-round lead by holing his second shot to the ninth, his last, for an eagle two, but on the resumption missed the green at the first and bogeyed.
