The Latest: Sock calls French Open umpire "atrocious."

PARIS (AP) — The Latest on the French Open, the year's second Grand Slam tennis tournament (all times local):9:30 p.m.

Jack Sock, the No. 14 seed, ranted and railed as he lost in the French Open first round for a second consecutive year.

His tormentor Tuesday was 136th-ranked Jurgen Zopp of Estonia, who won 6-7(4), 6-2, 4-6, 7-6(5), 6-3.

Sock blamed the Brazilian umpire, disputing her calls and questioning her competence.

"This is your job, right?" he said after serving a double fault to go 5-2 down in the second set. "Hard to believe."

On his way to losing the fourth set, he said to the umpire during a changeover: "You're atrocious. If we could request a new one, I would. This is shocking stuff.
