Associated Press Johan Santana can thank Mike Baxter and Adrian Johnson for helping him and the Mets make history Friday night at Citi Field. Baxter’s circus catch against the left-field wall in the seventh robbed Yadier Molina of an extra-base hit, and third-base umpire Johnson took extra bases away from former Met Carlos Beltran by blowing a call in the sixth inning. Add an incredibly dominant performance by Santana against the highest-scoring team in the National League, and the result was the first Mets’ no-hitter in the team’s 8,020th regular-season game as the Mets blanked St. Louis, 8-0. Santana’s no-no before an announced crowd of 27,069 was sealed in the ninth. He retired Matt Holliday on a fly to shallow center, got Allen Craig on a pop to shallow left and David Freese swinging at a 3-2 slider on his 134th pitch of the night. Santana walked five and struck out eight. He hugged catcher Josh Thole after fanning Craig and the entire Mets’ dugout ran out to mob him. All this happened on the night of Beltran’s return to Flushing. In another strange twist, the Mets battered St. Louis’ Adam Wainwright for seven runs over 6 ⅓ innings. Santana missed all of last season because of surgery on his left [pitching] shoulder, and the Mets have been monitoring his pitch count very closely, worried about the possibility of re-injuring his shoulder.
