Lydia not closing these out probably has more to do with the depth of the field these days than her ability and performance.
Lydia plainly didn't play well over the weekend!
The same field didn't prevent her from leading by two heading into the weekend.
True enough. She’s had a lot of ~60K checks this year. Her scoring average is back to where it was when she won a dozen times in 3 years. Maybe it’s a few shots here and there like you suggest, or maybe it’s a a different field these days. Probably some of both.
