(Reuters) - Penpix of the top women's contenders at the 2018 Wimbledon Championships:
Simona Halep (Romania)
World ranking: 1
Born: Sept. 27, 1991 (Age 26)
Height: 1.68 meters
Plays: Right-handed
Grand Slam titles: 1 (French Open 2018)
WTA match record in 2018 (won-lost): 35-6
2018 WTA titles: 2
Biggest weapon: Halep's speed, shot placement and remarkable anticipation earned her a first grand slam title last month and the same qualities can help the Romanian thrive at the All England Club.
Biggest weakness: Despite her French Open triumph, Halep has a reputation for folding under the pressure of big matches.
Caroline Wozniacki (Denmark)
Born: July 11, 1990 (Age 27)
Height: 1.77 meters
Plays: Right-handed
World ranking: 2
Grand Slam titles: 1 (Australian Open 2018)
WTA match record in 2018 (won-lost): 26-9
2018 WTA titles: 1
Biggest weapon: The fierce Dane is not one to back down from a fight and is ruthless in attack as she grinds her opponents down with her persistence.
Biggest weakness: Wozniacki has a tendency to get drawn into long rallies at the baseline rather than finding a killer shot or moving closer to the net and finishing off her opponent.
Garbine Muguruza (Spain)
World ranking: 3
Born: Oct. 8, 1993 (Age 24)
Height: 1.82 meters
Plays: Right-handed
Grand Slam titles: 2 (French Open 2016; Wimbledon 2017)
WTA match record in 2018 (won-lost): 21-11
2018 WTA titles: 1
Biggest weapon: Defending champion Muguruza has always proclaimed that grass is her least favorite surface but the intimidating Spaniard's hard-hitting shots and unwavering tenacity are not to be messed with.
Biggest weakness: Muguruza tends to lose sight of the bigger picture and focus too much on being a perfectionist on occasion, a trait that opponents can take advantage of to rattle the world number three.
Petra Kvitova (Czech Republic)
World ranking: 8
Born: March 8, 1990 (Age 28)
Height: 1.82 meters
Plays: Left-handed
Grand Slam titles: 2 (Wimbledon 2011, 2014)
WTA match record in 2018 (won-lost): 37-7
2018 WTA titles: 5
Biggest weapon: As she has shown throughout her impressive comeback, Kvitova's powerful groundstrokes and perfect timing can be too much for her opponents to handle.
Biggest weakness: The Czech is not known for her court coverage on the tour, giving her opponents a chance to exploit her slower pace.
Serena Williams (U.S.)
World ranking: 183
Born: Sept. 26, 1981 (Age 36)
Height: 1.75 meters
Plays: Right-handed

WTA match record in 2018 (won-lost): 5-2
2018 WTA titles: 0
Biggest weapon: One of the greatest players in the women's game, Serena has shown signs of returning to her best during her comeback and the American's punishing groundstrokes can unravel any opponent.

Maria Sharapova (Russia)
World ranking: 24
Born: April 19, 1987 (Age 31)
Height: 1.88 meters

WTA match record in 2018 (won-lost): 15-8
2018 WTA titles: 0
Biggest weapon: Sharapova's relentless fighting spirit along with her imposing presence, powerful shots and match control make her hard to beat.
