New York ? Johan Santana is a member of the New York Mets.

The two-time Cy Young Award winner passed his physical Saturday, finalizing the blockbuster trade that sent him from Minnesota to New York for four prospects: outfielder Carlos Gomez and right-handers Philip Humber, Kevin Mulvey and Deolis Guerra.

“We’ve been lacking what we consider a true No. 1 starter,” Mets general manager Omar Minaya said on a conference call. “It doesn’t get much better than Johan Santana.”

The Mets and Twins announced the deal one day after Santana agreed to a $137.5 million, six-year contract with New York – record riches for a pitcher. The deal includes deferred money and a club option for 2014 with a $5.5 million buyout.

Santana is 93-44 with a 3.22 earned-run averqage in eight major-league seasons, winning the AL Cy Young Award in 2004 and 2006 with the Twins. He has been less successful in the playoffs, going 1-3 with a 3.97 ERA.

The left-hander slipped a bit last year, finishing with a 15-13 record that included marks of 0-5 against AL Central champion Cleveland and 1-3 vs. Detroit. He dropped seven of his final 11 decisions as his ERA rose from 2.60 to 3.33 ERA, his highest since 2001. He also allowed a career-high 33 homers – most in the AL.
