Jack Sock has a competitive grass court record of 17–14 across 31 matches (54.8%). The record shows a player capable of competing here, though there is clear room to push the win rate higher.

At Grand Slam level (Wimbledon): Jack Sock is 6–6 (50.0%) across 12 Grand Slam matches — below .500, though the elite draw depth at the Slams makes that a notoriously difficult barrier to crack.

2 semifinals on grass without yet reaching a final — consistent deep runs that show the ability to string together wins across a full draw, with the step to the final still to come. 3 quarterfinals adds further depth to that picture.

By format on grass — best-of-five: 6–7 (46.2%); best-of-three: 11–7 (61.1%). Markedly stronger in three-set formats; the win rate drops noticeably in five-setters, which has direct implications for Grand Slam performance on grass.

Best season: 2014 — 4–2 (66.7%) from 6 matches. The best single-season display to date — a useful reference point as the grass record continues to develop.
