Very good start with 2 birdies on #2 and #5. Then 2 bogies on #6 and #9 because to 2 awful second shot which gave me 2 awful putts for birdie => 3 putts, a stupid par on #7 and a good putt on #8 for birdie. -1 after the front 9.
The B9 was not good despite 2 very good pars on #13 and #17, the 2 very dangerous holes with these greens. A very unlucky 7f putt for birdie on #14; the ball hit the inside of the hole, took pace and rolled down off the green. Another bogey on #16 because to a 3rd shot 7y long left which missed the green (not helped by the heavy facewind) but fortunately 2 good birdies on #11 and #18 to finish under the par.
Not bad but I predict a -5 or -6 for mag, the round is less hard than the first one on Merion.
