To add a little to the report from Cincinnati, it looked like Tsveti had a gameplan of just placing the ball back in with her forehand and being much more aggressive with her backhand (which makes sense to me). However, although Tsveti did have a few laser-like backhands, she missed several as well. Also, she got a few free first serve points early on but couldn't sustain this. McHale was getting more free points off her serve and dictating with her forehand (and targeting Tsveti's forehand), and the American used this to get a slight edge in the rallies. Combined with the better serving, this helped McHale get the first set.
Tsveti seemed completely dejected mid-way in the 2nd set, and I thought the match was over with McHale up 7-5, 4-2. Then Tsveti started hitting almost exclusively slice forehands, and this helped her get back into the match, as McHale started making more errors. Once Tsveti took the 2nd set, I thought she might have the momentum to win.
But Tsveti completely abandoned the slice forehand in the third, and the same pattern of the first set returned. McHale won the first point of 3 service games in a row by serving aces or unreturnables out wide to Tsveti's forehand. Tsveti couldn't get back into it and was obviously frustrated. On the forehand side, she would either hit soft and short or hit it extremely hard, and only one of these blasts went in.
Although the Cincinnati facility was pretty nice, there was an occasional problem with sound disturbing the players. There were speakers throughout the complex so that sounds from center court could be heard in other areas. At this point in the day, there was also a live band nearby playing that could be easily heard. But it became worse when this music was joined by singing on center court coming through a nearby speaker -- it was pissing me off trying to watch the match, so I'm sure it bothered the players. I think Tsveti and her father were complaining to the judge about this a few times, but the judge wouldn't (or couldn't) do anything about it.
Kiril moved around the court throughout the match -- not too much of a crowd -- and was generally cheering positively for Tsveti. On one break point, Tsveti hit the return out and acted upset, and Kiril said, "You're giving her presents". I also think I heard Tsveti say, after missing another first serve, "Get in, mother f*****" (All this was in Bulgarian, of course.)
(Not trying to make her look bad; she behaved pretty well, especially compared to what I saw in the Rodionova vs. Strycova Zahlavova match a couple of days before.)
Hopefully, she can be more consistent with her backhand and put a little more on the forehand in the upcoming hard court matches.
