Fleury blanked the Rangers on back-to-back nights, helping the Penguins claim a 2-1 lead in this Eastern Conference semifinal series. He followed up a 22- save performance in Sunday's 3-0 win at Pittsburgh by stopping 35 more shots in Game 3 on Monday.
Sidney Crosby ended his 13-game playoff goal-scoring drought, but the woes continue for the Rangers' power play.
New York totaled 10 shots while finishing 0-for-5 on the power play and has failed to score 34 straight times with the man advantage.
The Rangers played on back-to-back days for the second time in these playoffs (Games 6 and 7 in the first round against Philadelphia), and Monday's contest was their fifth in seven days overall.
New York will look to even this series Wednesday night.
