BOSTON (AP) --- Sylvia Hatchell became the third women's coach in NCAA history to join the 900-win club on Thursday night, reaching the milestone when No. 16 North Carolina beat Boston College 80-52. As the players dribbled out the final seconds, Hatchell finally let a smile come over her face and accepted the congratulations from her assistant coaches and even one of the referees. Xylina McDaniel had 15 points and seven rebounds for North Carolina (21-3, 9-2 Atlantic Coast Conference). Tierra Ruffin-Pratt scored 14 with six rebounds and six assists, and Krista Gross had 12 points and eight rebounds.
HATCHELL MAKES HISTORY WITH 900TH WIN
With the win over Boston College on Feb. 7, Sylvia Hatchell became just the third women's coach in history to reach 900 career victories. Hatchell, who enters Sunday's game with a career record of 900-317 in 38 seasons, joined Pat Summitt and Jody Conradt in the exclusive 900-win club. Hatchell is also the active leader in wins, two ahead of Rutgers head coach C. Vivian Stringer's 898.
TAR HEELS WIN TWENTY AGAIN IN 2013

• Carolina has won 20 games under Sylvia Hatchell 19 times in 27 seasons and 11 times in the last 12 campaigns.
• The win on Jan. 31 marked the first time Carolina has reached 20 wins in January since the Final Four team of 2006-07. That squad started 24-0 and finished 34-4. The 34 wins stands as the single-season school record.
• Hatchell has coached her teams to at least 20 wins on 29 occasions in 38 seasons, tied for third-most nationally. Only Pat Summitt (36) and Vivian Stringer (32) have coached more 20-win seasons.
• In addition to her 19 20-win seasons in Chapel Hill, Hatchell teams won 20 or more games 10 times in 11 seasons at Francis Marion.
WINNING WITH DEFENSE
Carolina has been tenacious on the defensive end so far in 2012-13, holding opponents to just 58.2 points per game and 34.7 percent shooting from the field. The current school record for opponent scoring average is 55.0 points per game in 2006-07. The Tar Heels have won three times in 2012-13 when scoring fewer than 60 points, something that had only happened once since 2005 prior to this season.
On Jan. 6, Carolina established a new school record for fewest points in a win in the 48-45 victory over Virginia Tech, breaking a record that had stood since 1976. The Tar Heels currently rank in the top 25 in the nation in steals (1st), blocks (14th) and field-goal percentage defense (24th).
The numbers look even better when adjusted for Carolina's up-tempo style, as the Tar Heels are eighth in the country in points allowed per possession. According to WBBstate.com, UNC allows just 0.73 points per opponent possession.
