Need help with 3 signatures on 1969 NL All Star team ball.

Panel 1 - Who is signature between Larry Dierker & Cris Cannizzaro?
Panel 3 - Who is signature on top, above Grant Jackson?
Panel 2 - Who is "Dave" between Bob Gibson & Bill Singer?

My close friend was ass't clubhouse manager on visiting side. He got ball signed and gave it to me.

All players on NL roster are identified, and on the ball, except Cleon Jones, McCovey, Phil Niekro & Glen Beckert. None of those autographs match up with my 3 unidentified signatures with exception of McCovey being the one above Grant Jackson. Dave Bristol as a coach and is on the ball, so it isn't him. "Dave" looks like Dave Concepcion but his rookie season was 1970.

Please solve my 50 year old mystery!!

Thanks!
