Can't say Sanchez's and Buehrle's feats were a surprise -- not if you believe in trends.
Even before Sanchez broke the ice on July 10, this three-month-old season had seen a remarkable assault on no-hit territory.
In mid-April, no-hitters were threatened on four consecutive days by one rookie (Oakland's Trevor Cahill) and three veterans (Ted Lilly, A.J. Burnett and Tim Wakefield).
No fewer than 21 bids have been taken past the sixth inning. There is no historical documentation of where that trend rates -- but for a reference point, all last season, there were 21 such serious no-hit bids (besides the realized no-hitters by Jon Lester, Jered Weaver and Carlos Zambrano).
The 2009 chronology of no-hit attempts (who broke it up, and how):
