Do the Blue Jays worry about Marco Estrada's curious recent struggles?
About a defence that suddenly looks slow, porous and generally unreliable?
Or perhaps about the ice-cold offence?
How about all of the above?
The Blue Jays kicked the ball around, failed to hit and saw one-time ace Estrada knocked around again on Friday night in a troubling 13-3 loss to the first-place Red Sox that pushed the club two games back with a pair of games remaining in this series.
The scuffling Blue Jays fell for the fourth straight time and have now dropped 6-of-7.
