BALTIMORE, Md. --  Fourth-ranked Johns Hopkins continued its unbeaten season with a 4-1 victory against Springfield in the second round of the 2011 NCAA tournament to improve to a perfect 21-0 on the season, Sunday night at Homewood Field. Senior Paulina Goodman made history in the win with the Blue Jays first hat trick in a NCAA tournament game.

The Blue Jays season will continue as they move on to face Amherst in the third round, marking the fourth trip in as many seasons. The Pride finish their season at 15-4-2 after their fifth run in the NCAA tournament in the last seven years.

Goodman wasted little time in the opening frame taking a quick pass from freshman Hannah Kronick near the front of the box to chip the ball into the back of the net just out of the reach of the Springfield junior goalie, Erin Greenstein early in the 11th minute.

Kronick once again connected with Goodman in the 35th minute, feeding the ball through two Pride defenders to lead Goodman to the top right corner of the box. Goodman drilled the ball into the top left corner over Greenstein's head for her second goal of the game and 12th of the season.

A quick 90 seconds later, it was the freshman's turn at a goal as Kronick collected the ball off the foot of senior defender Jessica Hnatiuk to slip the ball past Greenstein and give the Blue Jays a 3-0 lead. The goal was Kronick's 19th of the season to tie senior Erica Suter's team-leading season goal total and is just one goal shy of the single-season freshman goal record.

Goodman put the finishing touches on her second hat trick of her career and this season in the 42nd minute, this time taking a quick pass from senior Leslie O'Brien around 10 yards out of the net and once again chipped the ball over the reach of Greenstein to put the Blue Jays up 4-0 going into half time.

The Pride scored last in the game in the middle of the 66th minute when sophomore Vicky DiNatale wrangled the ball off a corner kick from senior Janelle Jahoda and shot the ball past junior goalkeeper Meredith Maguire to cut the Blue Jay lead to 4-1.

The Blue Jays would hang on to the 4-1 lead and advance to the next round of the NCAA tournament. Maguire needed just five saves in her eighth win for the Blue Jays this season while Greenstein suffered the loss for the Pride with five saves of her own. Greenstein falls to 14-3-2 for the season.

The Blue Jays led in shots 15-11 and held the advantage in corner kicks 5-1.
