When Serena Williams beat Simona Halep Wednesday night at the US Open she put herself in line to win a record breaking23 grand slam tournaments during her Tennis career. With just two games to play and win, she could set that amazing record. There is another personal hurdle to overcome and this requires just one more win.

Potential first 4th grand slam final in a single season

If she beats Karolina Pliskova in the semi's, she will advance to her 4thgrand slam final in a single season for the very first time. If she gets through and takes the finals Williams will have won her7th US Open tournament.

That would beat the record of six titles she currently shares with Chris Evert, so there are a lot of reasons for her to give it her best shot.

Her game against Simona Halep that qualified her for the semi-finals was no doddle in thepark and she had to work hard. She only converted four of a potential 20 break point opportunities, and although she got in 50 winning strokes, she also dropped 43 unforced errors.

Pliskova is a player on the rise

The women'ssemi-finals will be played on Thursday 9th at 7.00 EDT and Serena will have to face off against Pliskova who beatAna Konjuh. She also knocked out Venus Williams in the 4th round. Serena has played against Pliskova once before back in 2014 and Serena took the game in straight sets.

Pliskova has not the same experience behind her as Williams, and played her first senior grand slam tournament in the 2012 French Open. That does not mean she has not got the 'go' in her to threaten Serena's record breaking ambitions. In 2015 she climbed into the top 20 rankings after reaching the final at the 2015 Apia International in Sydney and saved Serena's #1 ranking spot when she beatAngelique Kerberat theWestern & Southern Openlast month.

2015 US Open was a missed opportunity for Serena

Last year, just when the semi's looked like a real opportunity for a 7th US Openwin,Serena lost toRoberta Vinci, who then went on to lose toFlavia Pennetta. Pennetta is not in the contest this year as she retired from professional tennis last year.

Serena took her first US womens singles title in 1999 when she beatMartina Hingis.

She did not make it to the finals the following year and in 2001, lost to her sister Venus Williams. Since then she has won the 2002 US Open, the 2008 tournament and then in stunning display of consistency took the 2012, 2013 and 2014 prize money.
