My first choice for the Mets open rotation spot(s) is Ben Sheets. When healthy, he is a dominant, #1 type pitcher. I think Omar Minaya is reluctant to go after Sheets because he fears him turning into a younger version of injury prone Pedro Martinez and El Duque. I see Andy Pettitte as the next best option. Compare the FIP's of various pitchers:
Pettitte is not that big a dropoff from Derek Lowe. Forget Oliver Perez. The reason Pettitte isn't getting the respect he deserves this offseason was his inflated ERA (4.54 in 2008) due to bad luck and poor defense (see: Derek Jeter and Robinson Cano). He is a near lock for 200 IP even at age 36 and would be the #2 pitcher in the rotation. FanGraphs pegs Pettitte's 1-year contract value at $15 million and BtB said $14 million. He turned down 1-year and $10 million from the Yankees, and I would love to see the Mets offer as much as $12-13 million for 1 year of Pettitte's services.
