Just 15, Mississauga, Ont's Bianca Andreescu reaches the final of the prestigious Orange Bowl

The Orange Bowl isn't quite what it used to be, but it's still one of the most prestigious junior tournaments outside the Grand Slam events.

And 15-year-old Bianca Andreescu of Mississauga, Ont. is in the girls' 18-and-under finals.

The Canadian, No. 15 in the ITF junior world rankings and seeded No. 9 going in, upset No. 2 seed Dalma Galfi of Hungary 2-6, 6-4, 6-2 in the semi-finals Saturday to reach the final, where she will meet No. 6 seed Kayla Day of the U.S.

Galfi is two years older than Andreescu.

Ranked No. 37 going into the Internationaux de Repentigny, a big junior event held outside Montreal as the tuneup for the US Open juniors, Andreescu has had quite a surge late in the season.

She won the singles title, defeating countrywoman Charlotte Robillard-Millette in the final, and reached the doubles final with fellow Ontarian Katherine Sebov.

After a first-round loss at the US Open (injured, she withdrew from the doubles), she led Canada to a third-place finish at the junior Fed Cup in Spain in September. Andreescu went 9-1; her only defeat came with Robillard-Millette in the semi-final doubles, the deciding match against the Czech Republic.

She then reached the finals of the Grade 1-level Yucatan Cup in late November, losing to Day, and won the doubles with another Canadian, Vanessa Wong.

The 15-year-old was on fumes when she arrived at the Eddie Herr tournament last week, scheduled to play on the Monday on a completely different surface, after the trip from Mexico. But despite losing in the second round of singles, she still made the doubles semi-finals.

And now, the capper on her season. Ranked a career-best No. 12 after Eddie Herr, she will surely make her top-10 debut in the next ITF rankings with her efforts in Plantation, Fla.

Tennis Canada undoubtedly has seen her potential for awhile now. Not only did they not mandate that she join the rest of the hand-picked prospects at the national training program in Montreal, they assigned Frenchwoman Nathalie Tauziat, a former world No. 3 and Wimbledon finalist, to coach her rather than one of their staff coaches. Tauziat has been doing multiple weeks with Andreescu since the spring clay-court season, and has been with her on this last stretch.

The last Canadian to win the Orange Bowl was Gloucester, Ont.'s Gabriela Dabrowski, who defeated Kristina Mladenovic of France to take the 2009 title. Carling Bassett won it in 1982, and Mike Belkin (whose name came up often during Milos Raonic's Grand Slam runs in 2014) won it in 1961 (the previous year, Belkin won the 15-and-under division)  (the illustrious list of past Orange Bowl champions is here).

Bjorn Borg won it in 1972, John McEnroe in 1976, Roger Federer in 1998 and Caroline Wozniacki in 2005.

Andreescu took the girls' 16-and-under Orange Bowl title just a year ago, the fourth consecutive Canadian to take it after Erin Routliffe in 2011, Gloria Liang in 2012 and Robillard-Millette in 2013.

For those already looking for the next wave, that streak was broken in 2015; No. 8 seed Brindtha Ramasamy and No. 13 seed Tiffany Lagarde lost in the third round.

On the boys's side, Eddie Herr champion Félix Auger-Aliassime was upset by Toru Horie of Japan in the second round. It's been rare for young players to be able to put together back-to-back winning weeks at the Eddie Herr - Orange Bowl combo given the heat and the length of matches on the Har-Tru surface. Austria's Dominic Thiem, currently ranked in the ATP Tour's top 20, did it in 2011 at age 18, three years older than Auger-Aliassime.

If she wins, Andreescu will be the first female player since Mary Joe Fernandez of the U.S. to win the 16s and 18s in back-to-back years. Fernandez, now a television commentator and the captain of the American Fed Cup team, did it 1984 and 1985. Chris Evert won the 16-and-unders in 1968 and the 18-and-under title in both 1969 and 1970.

On the boys' side, Ivan Lendl did it in 1976 and 1977 and Jim Courier in 1986 and 1987.
