Final, St. John's Prep 5, Needham 1 -- More dominant play from the Eagles in the third backed by goals from Devin Murray and Shane Eiserman, and Prep skates away with the victory to move to 2-0 in Super 8 play. With a win tonight from BC High or a win Sunday over BC High, St. John's Prep can guarantee itself a spot in the crossover round.

End of 2nd period, St. John's Prep 3, Needham 1-- The Eagle lead stays at two thanks to a goal from Colin Blackwell 57 seconds into the frame. The senior charged the Needham zone for a one-on-two, but by the team he reached the hashes, he'd already deked through both defenders. Blackwell roofed the puck by Murray from right atop the doorstep.

Needham had consecutive power-play chances right after the Blackwell goal, but failed to convert, and didn't get on the board until the 2:08 remained in the frame. No word on Rocket forward DJ Walsh's religious views, but either way, the junior's Ash Wednesday prayers were answered when he whipped a desperation centering pass into a pack of Prep defenders. The puck bounced off an Eagle leg and skidded five-hole on goalie David Letarte, cutting the deficit to 3-1.

End of 1st period, St. John's Prep 2, Needham 0 -- Freshman Shane Eiserman put the Eagles on the board first, but credit should really go to senior Harvard-commit Colin Blackwell. The standout broke from the left halfwall with the puck and emerged with it in the slot after deking around the entire Rocket defense, which was cramped mostly around the left hashmarks. From the slot, Blackwell wristed one in front, where Eiserman's tip bounced off Needham goalie Connor Murray and in for the 1-0 lead.

Nick Pandelena stretched the lead to 2-0 with a buzzer-beater at the end of the frame. Yes, that's right, a hockey buzzer-beater. The defenseman wound and fired a desperation slapper from the right point, and just before the horn sounded, the shot zipped under the crossbar.
