RFI sandpiper but which one?

[gb_eh]

Need a hand with the id of these two sandpipers (two different shots of each). They were not together, shot on different days:

1st (suspect this is a chick):




2nd:

The top one looks like a Semipalmated Sandpiper (in winter plumage) with the short, thick bill.
The bottom one I would say is a Lesser Yellowlegs. The bill doesn't look long enough for a Greater.
