Need help with some Cubs autographs
 

Hello all. Can anyone help identify the signatures on this Cubs cap?
I'm stumped. Any help would be greatly appreciated and thanks in advance,
Tony

2nd from left might be Matt Sinatro but I don't think he ever played for the Cubs. Top right may be Bob Rush who pitched for the Cubs in the 60s.

Sinatro was a coach for them so that one is correct (thanks). I'll check out Rush.

Top-right looks like Bob Brenly to me.

Brenly looks right to me. Thanks!

Lower right might be Don Baylor.

I think the one above Sinatro is Ivan DeJesus. I'm not convinced the bottom right one is Baylor. There is no drop down y.

Lower right looks like Dennis Martinez. It looks familiar from my in person days of the 80's and 90's

Could be. If it is, does anyone know what his association with the Cubs would be? I have no recollection of him being with the Cubs in any capacity.

Could bottom right be Dan Plesac?

second one from the left could be Fergie Jenkins--it's a scrawl, but the F and the ending s are very similar to his flourishes
