I mentioned in comments but forgot to post on the front page that nobody got the exact answer (June 7, 3B) in the Marte pool. I’m declaring David Remy the winner, with June 8 at third base. There was a tie for second. Bledsoe had June 5, third base, while Sansho had June 6 but left field.

All three can if they desire choose a worthless prize, a book from my box of discarded books nobody will ever read.
