Even those watching may have questioned if Mets closer Francisco Rodriguez took the mound this afternoon.   Against the Cardinals earlier today in his  Spring debut  K-Rod pitched a 1-2-3   7 pitch inning that you could have missed if you blinked an eye...just the way he likes it.   Rodriguez  tossed a hitless  9th with the Mets down 5-4, keeping the game in tact, and then earned the win as Angel Pagan  smacked a 2 run walk-off homer just over the right field wall.  "I'm going to be a secret weapon this year," Rodriguez said after the game.   "In and out.   Pay attention"Met fans have to love the confidence of their closer heading into Opening Day, especially after struggling in the second half of the season  and not having many chances to redeem himself  last year.   However, at this point I'm not sure anything K-Rod does will ever be a "secret".  It was still good to see Rodriguez in top form...let's just hope we actually need him this year.  The Mets will need K-Rod's curve to break even harder this year
