For the three-game series against Boston at Safeco Field that starts Friday, the Mariners rotation sandwiched Chris Jakubauskas and Jason Vargas around Erik Bedard.
Now Bedard will likely be skipped because of a tender hamstring - and replaced for one turn by Garrett Olson.
The Red Sox offense, then, faces three guys who began the '09 season in the Seattle bullpen - or Tacoma.
The team hopes Bedard bounces back in time for his next start, and the bullpen will be a bit short since long relievers Vargas and Olson are now starters.

Boston, by the way, will counter with Jon Lester, Josh Beckett and Justin Masterson.
