The sixth-seeded Buckeyes (21-10) trailed just 33-32 at halftime. But BC (27-6) outscored OSU 30-16 in the second half. OSU went eight minutes and three seconds without scoring in one stage and made just 4 of its first 24 shots from the floor in the second half.
"This was an NCAA Tournament game with the opportunity to advance to the Sweet 16," said Jim Foster, wrapping his second year as the OSU coach. "There are three four-team tournaments you have to negotiate. We're not ready to negotiate that yet. We have a lot of work to do in the off-season."
Boston College got balanced scoring from Amber Jacobs (17 points), Kathrin Ress (16) and Jessalyn Deveny (15).
Freshman guard Brandie Hoskins scored 13 of her game-high 16 in the first nine minutes for OSU. Caity Matter was hounded into an off night, hitting just 4 of 12 shots and finishing with 10 points. BC double- and triple-teamed OSU's inside duo of LaToya Turner (seven points) and Jessica Davenport (four points).
Davenport had a string of 15 straight double-digit scoring games broken, while Turner was held under 10 points for just the fourth time all year. Turner grabbed a game-high 10 rebounds in the final game of her roller coaster five-year career.
"This is the end," Turner said. "There is nothing to really say. That's it."
BC advances to play the winner of Kansas State-Minnesota next Sunday in Norfolk, Va.
"We came together at the defensive end," said BC coach Cathy Inglese. "We were able to shut down their inside scoring and also make it tough for them to get off perimeter shots. Our defense got us going."
Foster's Buckeyes were eliminated from the second round of the NCAA Tournament for the second year in a row. OSU came into the game ranked No. 1 nationally in field goal percentage at 51.5 percent. But the Buckeyes were held to 36.8 percent (21 of 57) in this game and also made just 2 of 9 free throws. Plus, they committed 19 turnovers.
"We just didn't do the little things we needed to do for us to score and make shots," Matter said. "We didn‘t play together as a team."
Hoskins kept OSU in the game early as BC led by as many as seven points on three occasions in the first 20 minutes. But the Buckeyes capped the half on an 8-2 run as Candace Dark nailed a three-pointer and made a layup and Matter drilled a trey with 19 seconds left in the half to cut the halftime deficit to 33-32.
OSU's Kim Wilburn then stole the ball and scored to open the half and put the Buckeyes up 34-33. Matter's 16-foot jump shot later gave OSU its last lead at 37-36 with 17:14 left. After Davenport rebounded her own miss and scored to cut the BC lead to 40-39 with 14:38 left, BC went on an 18-3 run over the next 11 minutes to push its lead as high as 16 at 58-42.
A Matter three-pointer with 6:35 left ended an eight-minute OSU scoring drought and cut BC's lead to 50-42. Wilburn then stole a BC pass and was headed in on a two-on-one break. But she missed Matter with the pass, which flitted out of bounds. The Golden Eagles methodically reeled off the next eight points to put the game away.
"That is a fundamental basketball play you just have to make," Foster lamented.
* Inglese and her players praised the OSU-partisan crowd for their showing.
"Can I just say that was the most incredible atmosphere," Jacobs said. "They were loud."
Inglese added, "This was a great venue to play in. It was loud. We saw on ESPN a lot of games in empty arenas. I think our players would rather play in a venue like this. It was a fun crowd. I think they fed on that and really enjoyed that."
* OSU announced a scoring change on Davenport from Saturday's NCAA win over West Virginia. After reviewing the videotape, OSU sports information officials found that Davenport had incorrectly been credited with a miss with 16:33 left in the second half.
The scoring change gave Davenport an OSU single-game record of 10 for 10 on field goal attempts. It also tied an NCAA record for a first- or second-round tournament game.
* This was OSU's 13th NCAA appearance and the Buckeyes now have an all-time tournament mark of 15-13. Foster is now 26-18 in 18 NCAA appearances over his 26-year career. That includes a 2-2 mark at OSU.
* The loss was OSU's first in six games at St. John Arena under Foster.
The tournament was played at SJA due to Ohio girls state basketball tournament action at Value City Arena this past weekend.
The crowd figure bettered OSU's season high home mark of 8,159 for the Saturday game against West Virginia. OSU's largest crowd at VCA was 6,754 for the regular season home finale against Illinois.
* OSU's 14 field goals were a season low. The previous low as 17 in a loss at Michigan State. The 48-point output was one more than the season low of 47 set in that same game.
