Mayer is an all-court player known for his unique and creative style of play. He has an unusually long take-back on both his forehand and two-handed backhand and generally hits more top-spin than flat on both wings. Despite his height, his groundstrokes and serve lack power, but are consistent and unpredictable. He uses a variety of spins on both wings to mix his shots up and hit drop-shots. He is well known for his double-handed backhand slice, similar to that of Fabrice Santoro and Jimmy Connors, and often pulls off jumping backhands and jumping slice drop-shots which catch his opponents off guard. His drop-shots are particularly effective on clay and grass, where he has had most success. Despite having a weaker, top-spin serve, Mayer occasionally serve and volleys and is also known for his two-handed backhand cutting volley. He also often uses a Chip and charge tactic during points to finish points off. This makes him unpredictable and tricky to play against.
Mayer's biggest weaknesses are his lack of match consistency and fitness, having had inconsistent results throughout his career and a relatively small build. He has also suffered from numerous injuries throughout his career, most notably his groin injury in 2015 that prevented him from playing for more than a year. However, he has since made a comeback, winning his second title at the 2016 Halle Open.
Current through the 2017 US Open.
