Boston Bruins

A few observations from the Bruins’ 4-game winning streak

More than a half hour prior to the club’s scheduled practice Saturday morning in Brighton, Tuukka Rask was in net and fielding shots from injured forwards Brad Marchand and David Backes.

Coach Bruce Cassidy said Rask, a backup for the club’s recent string of four straight wins, is the starter Sunday when the dysfunctional Oilers visit the Garden for late-afternoon matinee. Rask’s most recent start, a loss, was Nov. 15 in Anaheim.

Prior to the start of the 11 a.m. workout, the Bruins announced that they recalled forward Jordan Szwarz from AHL Providence on an emergency basis. They also returned defenseman Rob O’Gara to the WannaB’s.

A few quick observations regarding the season-high four-game winning streak:

■ The Bruins outscored the opposition, 11-7, with the goals coming from a chorus of 10 different scorers. Rookie Jake DeBrusk, with strikes against New Jersey and San Jose, was the only repeat scorer in the bunch.

■ Anton “The Rubber Baron’’ Khudobin recorded all the wins in the Boston net, limiting opponents to 1.75 goals per game and stopping 94.5 percent of the shots he faced.

■ The Bruins led in the four games by a collective time of 205:41 and trailed for only 1:27 (during the first period in San Jose). Average lead time: 51:25 per game.

■ Of their 11 goals scored in the four games, nine of them involved players with NCAA playing experience. Four were scored by ex-NCAAers: Charlie McAvoy (BU), Danton Heinen (Denver), Sean Kuraly (Miami, Ohio) and Matt Grzelcyk (BU).

■ The Bruins squeezed out two-goal leads in three of the four games. Prior to Friday’s action, clubs able to amass a two-goal lead in games this season were a collective 244-13-19, garnering an astounding .918 point rate.

■ The 20 shots recorded by the Penguins Friday was a team low for 2017-18. It was also the stingiest the Bruins have been this season.

■ The Bruins went 0 for 10 on the power play during the four victories.
