Carpenter is now in serious condition, her family said in a statement. They said she's "an attractive, positive, upbeat, hardworking single mom who would do anything" for family and friends.

The woman, identified as Tonya Carpenter - her family released a statement Saturday afternoon saying she’s in "serious" condition and they are "grateful to all who have reached out with thoughts and prayers but are requesting privacy at this time as Tonya recovers". The NHL added protective netting behind goals after a teenage girl was struck in the head by a puck at a Columbus Blue Jackets game in 2002.

The woman was attending the game with her husband and son, the Globe reports. The medical staff applied first aid to the injured fan, who was bleeding heavily from the injury, before she was loaded onto a gurney with the help of police officers and other Fenway personnel.

Just about all MLB ballparks have signage warning fans that foul balls and broken bats can be risky, and tickets include disclaimers shifting responsibility to the fans to protect themselves.

Tonya Carpenter was hit with a baseball bat Friday at Fenway.

Lawrie, from Langley, B.C., was out of the A’s lineup Saturday, but manager Bob Melvin said it was because of a back issue, not because of any psychological effects after the incident. Lawrie entered as a pinch-hitter in the eighth inning.

Koji Uehara, the fifth Red Sox pitcher, worked the ninth for his 13th save. And hopefully, she gets better.

Oakland Athletics third baseman Brett Lawrie had been batting at the time when his bat shattered on a pitch in the second inning and struck the woman, who was sitting down the third baseline. Emergency crews tended to a bloodied Carpenter and wheeled her off the field on a stretcher.

There are signs posted on the low retaining wall facing fans in the front row that read: "Be Alert".

Alex Merlis, of Brookline, Mass., said he was sitting in the row behind the woman when the broken bat flew into the stands. Fans said they saw the bat hit her head. Cinder needed a lot of care after she was injured in the July 2014 Carlton complex fire in the Methow Valley.

"Obviously, there is a lot of velocity involved with anything that goes into the stands, whether it's errant throws, broken bats, and foul balls - especially foul balls".

The batter, Lawrie, said after the game that at first he didn’t realize the severity of the woman’s injuries because he was running to first base. You come into a game, you see I do not know how many foul balls fly into the stands every game and for the most part, everyone is fine all the time, and these things are coming in at 100 miles an hour.

Major League Baseball expressed its concerns with flying broken bats and the danger they posed in 2008.

"Both have pitched out of the bullpen, both have given United States very good starts", Red Sox manager John Farrell said before the game. Since the beginning of the 2009 season, multi-piece bat failures had been reduced by 50 percent, according to league spokesman Michael Teevan.
