Bruins goalie Tuukka Rask had the lowest save percentage (.899) and the highest goals-against average (2.94) of the starting goalies on the eight teams that advanced to the second round.
Rask allowed four goals three times against the Maple Leafs, including Game 5, when the Bruins had a chance to win the series, and in Game 7, when Boston trailed 1-0 and 2-1 in the first period and 4-3 after two periods before winning 7-4.
Rask has allowed four goals in five of his past 10 starts, including a 4-0 loss at Tampa Bay on April 3.
"Tuukka is fine," Bruins coach Bruce Cassidy said. "He's been there. He's going to be good for us. That's that. We've just got to be good in front of him as well."
