backhand, which he used to disrupt the rhythm of the point and to construct offensive positions. He also possessed a strong serve and a functional set of volleys. Haas was known for his refined footwork and racquet skills, both of which he used to construct quick defensive-to-offensive transitions. He was widely considered one of the best players to have never won a grand slam, having been restricted by numerous injuries. Reviewers described him as having nice "fluidity" and how his game overall allows him to adapt to most situations, as demonstrated by his equal win percentage over both right and left-handed players, as well as his relatively even win percentages on all surfaces. Haas' mental game was described as solid, boasting a positive win record in deciding sets (3rd or 5th). Personal life On 27 January 2010, Haas became a United States citizen, but continued to represent Germany in tennis. Since 2010, Haas has been engaged to actress Sara Foster. They have two daughters together, Valentina and Josephine. Haas is the son-in-law of David Foster.
