Sandpiper ID help

My dad spotted this sandpiper in the Cumberland Farm fields in Middleboro, MA. It seems to be similar to a least sandpiper (yellow legs) and a juvenile semi palmated. The splotches on the wings are not characteristic of either type (at least according to my bird books). Please note the prominent streak above its eye and the secondary streak above that one as well as the dot behind the eye. My dad believes that the bird was much too large to be a least sandpiper.

I will post three photos. Any help you can provide will be greatly appreciated.

Here is photo #2

Here is photo #3

Pectoral Sandpiper. Probably a juvenile. The streaked breast ending abruptly, yellow legs and streaked brown cap above white eyebrows pretty much eliminate anything else for me. I see a faint brown wash on the chest in photo #3, which is the reason for saying probably a juvenile.

Thanks Jim!
