I kinda got this crazy idea to make a comment, on every single Wimbledon match in the first round. Idea behind it, is to get an argumented debate going on. Something like brainstorming. Because good picks will not fall from the sky, into your lap. You have to work for it.
So, lets get it started.
(all the lines, from Pinnacle)
Kimiko Date Krum-Ekaterina Makarova (+5 and u/o20)
Makarova has very decent record on grass, and also few titles, if I am not mistakes. Still, Date Krumm can be very dangerous on grass. She is very tricky to play against. Taking those groundstrokes on the rise, not allowing opponent much time for aticipation on the defense. Also pretty good at the net. Initial lean: over 20
Misaki Doi-Elina Svitolina (+4 and u/o20.5)
Hm... Asian player usualy do well on grass, but Doi hasn't show much on the tour, for quite some time now. Svitolina's favorite surface is grass. her ball striking is pretty good and she starts to feel it, she is hard to stop. Initial lean: Svitolina -4
Polona Hercog-Paula Ormaechea (-2.5 and u/o21.5)
Polona has improved her serve in past few seasons, but aside from that, I don't see her doing very well on grass courts. Ormaechea is underrated on faster courts. Initial lean: over 21.5
Ana Konjuh-Marina Erakovic (+2.5 and u/o21.5)
Haven't heard much about Konjuh, since that upset win in Auckland against Vinci. It is obvious that girl has talent, but the question is where her form is at the moment. Grass is the favorite surface for Marina Erakovic and it is time to show it. But since I don't trust Marina at all, I think that the under is the best play here. She might get the job done, as she should. Or dissapoint completely. Initial lean: under 21.5
Johana Konta-Shuai Peng (-2 and u/o 21.5)
Interesting one. Konta played some decent tennis sicne the begining of the grass season. But should she really be the favorite here? Peng is not in the best form at the moment, but I still think she has the game for the grass. Expecting a good battle. Initial lean: over 21.5
Alla Kudryavtseva-Barbora Zahlavova Strycova (+4 and u/o21)
Zahlavova might be slightly overrated because of those finals in Birmingham. Kudryavtseva is very decent player on grass. Good serve. Flat groundstrokes. It should be an interesting one. Initial lean: over 21 games
Sloane Stephens-Maria Kirilenko (-5 and u/o 19.5)
Grand slams usualy bring the best out of Stephens. She also played well in Birmingham. Kirilenko was able to perform well on grass in the past, but her performance in Hertogenbosch was an indicator, that she is currently in pretty poor form. There is not much value, backing Stephens here, but I still think it is better choice then Kirilenko. Initial lean: Stephens 2-0
Elena Vesnina-Patricia Mayr Achleitner (-6 and u/o 18.5)
Vesnina might be a solid grass court player, but the line seems bit to high. Mayr is not such a scrub. Initial lean: over 18.5
Yanina Wickmayer-Samantha Stosur (+4.5 and u/o19.5)
I am in the dark here. You never know what to expect from Stosur. Despite having some serious weapons for the grass courts, she slipped so many teams, in the early rounds of Wimbledon. I would like to fade her in this spot, but I am not sure if Wickmayer can do it. Oh well... Initial lean: Wickmayer +4.5
Rest of the comments, coming later. Now it's your turn guys. What am I missing? Where I went wrong?
