In the 5th set tiebreak, Sargsian was serving at 5-4 and Mathieu hit a return that clipped the line. The ball was called out even though Hawkeye (ShotSpot) showed the ball was clearly on the line. This was obviously a crucial point. It gave Sargsian 6-4 in the tiebreak and two match points instead of being tied up at 5-5. Mathieu complained about the call to no avail but it clearly aggravated him. In frustraion, on the next point (match point) he hits the return of serve into the middle of the net. Very dissapointing way to end an extremely high quality and entertaining match with lots of drama and intensity. Mathieu's service game at 4-4 in the 5th went to like 8 deuces. My confusion is that, at the time, Courier said he was glad that the officials got the call right and this was right after they had shown the Hawkeye replay showing the ball was in. Did Courier miss the Hawkeye replay? Why did he say the officials got the call right when they clearly got the call wrong. Hawkeye showed the ball in but the linesman called it out. :? The difference between 5-5 and 6-4 in the 5th set tiebreak is huge. BTW, I'm not taking anything away from Sargsian. He played his heart out and played a tremendous match coming back from 2 sets to love down. He deserved to win. Congrats to Sarge!!
