MONACO (AP) -- Jared Donaldson ranted at the chair umpire over a line call during his 6-3, 6-3 loss to Albert Ramos-Vinolas in the first round of the Monte Carlo Masters on Monday.
The 21-year-old American got irate with a call when Ramos-Vinolas was serving at 3-2, 40-0 in the second set. Donaldson thought the serve was out and pointed to the ground, shouting, ''There's a mark right here,'' and then screaming the same words inches from the face of French chair umpire Arnaud Gabas.
He then squared up to Gabas and shouted: ''Yes it is, yeah it is,'' as he insisted his mark was right and the umpire's call of in was wrong.
''You're not showing me one (accurate) mark,'' Donaldson yelled while Gabas started walking backward.
Donaldson received a code violation. He then sat in his chair, with Ramos-Vinolas leading 4-2, repeating ''supervisor'' over and over.
The tournament supervisor jogged on and spoke to Donaldson, while Gabas was back up in his chair.
Following a brief exchange, Donaldson laughed and said, ''Ah, I'm sorry. I hurt your feelings,'' as he appeared to mockingly extend his hand up to the chair umpire.
Donaldson, ranked 51st and making his first appearance at the clay-court tournament, was jeered by the crowd on center court.
