The Answer....
There were a few Mets ties in that All-Star game. Tom Seaver was the starting pitcher, pitched 3 innings, and was replaced by a pinch-hitter...future Met teammate Rusty Staub.
The National League squad was managed by Gil Hodges.
But the two key Mets directly involved in the play were Jim Hickman, then of the Cubs, who was an original Met. Hickman hit the ball that Rose scored on, a single to center-field. And then Amos Otis, who came up with the Mets and was traded prior to the 1970 season to the Royals, made the throw to Fosse to try to nail Rose.
Congratulations to Timothy Dougherty, who was the closest with his guess. His prize is on the way...
