CHAPEL HILL --- Xylina McDaniel scored 15 of her career-high 19 points after halftime and No. 11 North Carolina withstood a furious rally to top No. 20 Florida State, 72-62, Thursday night at Carmichael Arena. Waltiea Rolle finished with 18 points on 9-of-12 shooting and 10 rebounds as the Tar Heels won their 20th game and gave head coach Sylvia Hatchell her 899th career victory.
HATCHELL APPROACHING HISTORY
Head coach Sylvia Hatchell enters Sunday's game with a career record of 899-316 in 38 seasons, just one win shy of 900. Only two coaches in women's basketball history have reached this milestone - Pat Summitt and Jody Conradt - but Hatchell and Rutgers head coach C. Vivian Stringer are both on pace to get there in 2013. Hatchell currently holds the active lead, two ahead of Stringer's 897.
TAR HEELS WIN TWENTY AGAIN IN 2013
• With the win over No. 20 Florida State on Jan. 31, UNC reached the 20-win mark for the 24th time in program history 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 gotten to 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, good for fourth-most nationally. Only Pat Summitt, Vivian Stringer and Jody Conradt have coached more 20-win seasons.
• In addition to her 18 20-win seasons in Chapel Hill, Hatchell teams won 20 or more games 10 times in 11 seasons at Francis Marion.
TAR HEELS IN CARMICHAEL ARENA
• Carolina is 422-93 all-time in Carmichael, including a 49-10 record since the building re-opened after being closed for renovations from March 2008 to December 2009.
• The Tar Heels have won at least 13 home games in each of the last 12 seasons, including a school-record 18 during an undefeated 2007-08 home campaign.
• UNC has lost just 19 home games since the start of the 2001-02 season. The Tar Heels have been even more stingy against non-conference opponents, losing at home just twice outside of league play in the last decade.
WINNING WITH DEFENSE
Carolina has been tenacious on the defensive end so far in 2012-13, holding opponents to just 57.3 points per game and 34.0 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 20 in the nation in steals (1st), blocks (10th) and field-goal percentage defense (16th).
The numbers look even better when adjusted for Carolina's up-tempo style, as the Tar Heels are sixth in the country in points allowed per possession. According to WBBstate.com, UNC allows just 0.71 points per opponent possession.
