Sheldon Keefe couldn't been pleased at his Devils for the shoddy performance two nights ago in a 7-2 loss to the Bruins. The message should clear for tonight as Keefe will expect a more-focused effort in a dress rehearsal of sorts for the upcoming playoff series vs. the Canes. Three impressive wins preceded the Boston debacle, and Ruff tonight gives a rest to Jacob Markstrom, with Jake Allen getting one more tune-up in goal after mop-up duty in the last 9 minutes vs. the Bruins. The Pens are off of a 5-0 thrashing of the Blackhawks but prior had lost five of seven amid many defensive breakdowns. Play Devils on the Puck Line.
