Arvidsson ripped several winners to take the first set 6-3, before falling behing 1-5 in set two as Peer took control with a mix of
topspin defensive groundstrokes and flat groundstroke winners.
"She was returning very well, and she got more first serves in," said Arvidsson.
At set point a Peer backhand down the line winner evened the match a one set all.
"I played pretty good in the beginning," Arvidsson said. "But then I started playing in more her tempo. She slowed it down a bit.
She liked the longer rallies. She played well in the end. We had some tight games and she won the important points."
In set three the pro Peer crowd grew louder with their cheers of 'come on Peer' and 'go Peer' as Peer raced to a 5-2 lead following
Peer winners from an overheand and a forehand down the line.
"It always helps when there is support," Peer said. "They want you to win. It's nice when people are cheering for you."
"All three sets it was really really tough. She was playing very good and me too the whole match. But I think I changed a
little bit the tactic from the first set. I just was very aggressive. I tried to pull out this match and I did it."
In the final game of the match, Peer saved four breakpoints before closing the match out with an overhead winner.
"From 3-2 to 5-2 were the toughest two games." Peer said. "I was able to pull out a good game at 5-3 somehow... and I always kept
fighting, fighting and that's what gave (me) this match."
