Mets fans and collectors will appreciate these three baseballs used by two pitching greats in different eras. Two of the balls were in the potent left arm of Jesse Orosco when he notched his 99th and 101st career saves (May 27 and 29, 1987 vs. the Giants). Both are Official National League (Paul Giamatti) balls that feature the dates and save numbers while showing good use. The third ball was used by Pedro Martinez, though it is unclear in which game. That is an N.L. (Coleman) ball that comes with a COA, shows nice use and the signature rates 8/10.
