BOSTON (AP) -- Ohio State coach Jim Foster knew his team was fortunate to reach overtime.
Marscilla Packer scored 18 points, including a key 3-pointer in overtime, to lift No. 4 Ohio State to a 66-61 win over Boston College on Saturday.
"I think we were lucky to have a fresh start and go out and get a chance to win the game," Foster said. "I liked our team a lot in overtime. I didn't like us for the first 38 minutes."
The Eagles opened a 50-46 lead on Brittany Johnson's two free throws with 2:06 to play, but the Buckeyes forced a pair of turnovers and tied it on Packer's two free throws with 48 seconds left.
"We found a way to win," said Brandie Hoskins, who scored 13 points. "It was an ugly win."
Jessica Davenport, battling double- and triple-teams the entire game, added 12 points on 4-of-9 shooting for the Buckeyes (5-0). She's averaged 19 points in the Buckeyes' first four wins.
Kathrin Ress led the Eagles (6-2) with 16 points, Johnson had 15 and Aja Parham 12.
The teams were tied three times in overtime before Davenport's two free throws pushed the Buckeyes ahead 59-57. Packer then made a long 3-pointer from the left wing as the shot clock ran out for a 62-57 lead with 1:31 left in overtime.
BC's Brooke Queenan missed a potential game-winning reverse layup and the ball went out of bounds in favor of the Eagles with two seconds left in regulation. The ensuing inbounds was tipped into a group of players as the horn sounded.
"We put that play in practice yesterday for that type of situation," BC coach Cathy Inglese said of Queenan's miss. "We got the shot we wanted."
The Eagles outrebounded Ohio State 48-31 but turned the ball over 21 times to the Buckeyes' 10.
"Certainly the disappointing part is when you're up four in the last two minutes," Inglese said.
Ress had 10 rebounds but hit just 4-of-13 shots while playing only 29 minutes because of foul trouble.
"A disappointing loss," Parham said. "We can definitely take some positives out of it."
Ohio State, which led the nation in field goal percentage the past two seasons, led 23-22 at halftime despite shooting just 30.3 percent (10-of-33).
The Buckeyes' previous four wins were by 39 points or more.
