In tennis, Grinding is a playing style where a player stays at the baseline for long rallies.
They hit consistent shots to wear down their opponent over time. Grinders focus on getting every ball back rather than hitting winners. They have great endurance and mental toughness. Grinders often use topspin to keep the ball in play.
They wait for their opponent to make mistakes.
Rafael Nadal was known for the grinding style early in his career.
