On Friday, Luke Donald decided to give his regular caddy John McLaren the day off in order to have Robert Karlsson's side-kick, Gareth Lord operate as his bag man for the round.
The result was a 2-under 68, which was two strokes better than his opening round score.
While the improved performance was an added bonus, the caddy switch had nothing to do with the skills of either bag man. The reason McLaren had the day off was because Donald allowed him to attend the birth of his first child.

"For me that was an important thing in my life to be around for [the birth of a child], especially your first one, and enjoy that experience," Donald said. "But I know what he's like. He's very passionate about his job, as well, and he'll get back here when he's ready.
