Key facts and figures from Stanley Cup Final Game 4

The Chicago Blackhawks have turned a best-of-7 Stanley Cup Final into a best-of-3 series -- and they'll have two of them at raucous United Center.

The Blackhawks blew a pair of two-goal leads and a couldn't hold one-goal advantage in the third period before beating the Boston Bruins 6-5 in overtime Wednesday in Game 4 at TD Garden. Brent Seabrook's goal 9:51 into OT got the Blackhawks even in the series and gave them the chance to win the Cup by holding serve at home.

It was an up-and-down contest, replete with goals and scoring chances that were uncharacteristic of two of the best defensive teams in the NHL.

Here are some of the key facts and figures from Game 4:

1 ­-- Power-play goals scored by the Blackhawks during the Final. Chicago was 0-for-3 on Wednesday and 0-for-14 in the series before Patrick Sharp scored at 11:19 of the third period. Chicago had been scoreless in its prior 24 power-play opportunities since scoring in Game 2 against the Los Angeles Kings in the Western Conference Final.

2 -- Overtime goals by Seabrook, who got the winner at 9:51 of OT. The defenseman also had the winner in OT in Game 7 of the Western Conference Semifinals against the Detroit Red Wings.

2 -- Shorthanded goals scored by Chicago this spring after Michal Handzus beat Tuukka Rask during a first-period Boston power play. The other was by Michael Frolik in Game 2 of the Western Conference Quarterfinals on May 3. It was the first postseason shorthanded goal of Handzus' 16-year NHL career.

3 -- Overtime games during this year's Final. The most recent time there were as many as three OT games in the Stanley Cup Final was 1993, when the Montreal Canadiens won Games 2-3-4 against Los Angeles in OT.

5 -- Overtime victories by Chicago in this year's Stanley Cup Playoffs. The Blackhawks are 5-2 in OT; the Bruins  fell to 5-3.

6 -- Playoff goals this spring by Boston defenseman Johnny Boychuk, whose blast with 7:46 left in regulation led to overtime. The six goals are more than Boychuk has ever scored in a complete regular season.

8 -- Shots on goal by Sharp, the most of anyone on either team. The eighth shot became the Blackhawks' fifth goal. Sharp got all eight of his attempted shots on goal -- and the Blackhawks were on target with 47 of their 70 attempts.

10 -- Postseason assists by Boston's Jaromir Jagr, who had yet to score a goal this spring. The last player to reach double figures in assists in a playoff year without scoring a goal was Mike Ridley of the Washington Capitals (11 assists) in 1992.

11 -- Combined goals by the Blackhawks and Bruins in Game 4, matching the most scored in a Stanley Cup Final game that went past regulation. The other time 11 goals were scored in an overtime game in the Final was Game 1 in 1982, when the New York Islanders beat the Vancouver Canucks 6-5.

19 -- Players who've taken part in 200 Stanley Cup Playoff games. Jagr joined that group Wednesday when he took the ice for the Bruins. He's played for six teams during his career and made the postseason with five of them.

27 -- Overtime games during this year's Stanley Cup Playoffs. That's the second-highest total in NHL history, one short of the record set in 1993.

30 -- Consecutive penalty kills by Boston before Chicago scored on the power play in the third period.

38 -- Faceoffs won by the Blackhawks in Game 4; they lost 39. That was a huge improvement from Game 3, when Chicago won 16 of the 56 faceoffs.

40 -- Shifts by Chicago defenseman Duncan Keith, whose 32:37 of ice time was the most of any player. The Blackhawks played most of the game with five defensemen; Nick Leddy saw 2:37 of ice time, though the team didn't announce if he'd been injured.

42 -- Games since the Blackhawks had allowed more than one power-play goal. Boston became the first team to get two extra-man goals in the same game against Chicago since the Edmonton Oilers did it March 10.
