When predicting winners on hard courts, several key statistics can be influential. Players' hard court winning percentages, first serve percentage, and second serve points won are critical, as a strong serve can dictate matches on faster surfaces. Additionally, analyzing return stats, such as break points converted and return games won, can provide insights into a player's ability to capitalize on opponents' weaknesses. Groundstroke statistics, particularly forehand and backhand winners to unforced errors ratios, indicate consistency and offensive capability. Recent form, head-to-head matchups, and physical fitness should also be considered, as hard courts can be demanding and favor players in peak condition. Lastly, court conditions, such as indoor vs. outdoor hard courts, can influence performance due to variations in speed and bounce.
