Jason Giambi's heroics brought an exciting culmination to an otherwise ugly Yankees performance

  On a 0-2 slider, Toronto's closer B.J. Ryan served up what would be an astounding upperdeck homerun to Jason Giambi, and the New York Yankees plucked victory from the jaws of defeat.  Lost in the excitment of a walk-off homer, are the other aspects of a inferior effort the Yankees have put forth on a daily basis.  Chien Ming-Wang pitched ineffectively once again, Melky Cabrera made an inexcusable error, and Robinson Cano looked apathetic trying to lay down a bunt.  These are all tell-tale signs of a fundamentaly flawed ball club that can not get out of its own way.   Giambi's homerun provided a snapshot of the Yanks season so far, a talented and gifted bunch who have faltered to put together consistent play.  Giambi who have gotten hot of late, showed that he still have the ability to hit the baseball a long way, but can he and the Yankees do it on a fairly regular basis remains to be seen.  The Yankees dearly need Wang to perform as a #1 starter, otherwise they will continue to play up and down ball.  The true test awaits in the momentun a season altering homerun can bring. Will the Yankees energize their play to sweep a horrific Royals squad, or will their continued inconsistency plague them once again?
