Playing in the group ahead of Fowler, Thomas
and Grace, Kuchar had three birdies for a 3-under 32 on the front nine and rolled in a nine-foot birdie putt on the 167-yard 12th hole.
That gave him a share of 24th place along with veteran Phil Mickelson (who is a full 12 years younger than Langer) and ahead of young hotshots such as Rickie Fowler, Thomas
Pieters and Brooks Koepka plus the big names who missed the cut.
Carmarthen, second half: James; Cummins, Belle, Fowler, Thomas
; Behaldan, Morgan, Green, Brooks; Thomas, Follows.
Andy Fowler, Thomas
Moore (penalty) and Liam Dawson were on target for the Mariners.
SKY BLUES: Gary Montgomery; Aaron Shanahan, Daniel Hall, Lee Fowler, Thomas
Cudworth, Richard Spong, Laurent Delorge, Marco Brancati, Stephen McPhee, Martin Grant, David Pipe (Brian Ford, 82).
