You can't play against players ranked about 60 or so below you and call that a credible winning streak. She has a two match winning streak.
It is not as impressive because of the lower tiers, but win streaks are impressive no matter what. Sprems was impressive on the ITF circuit, as well as Li Na's. The reason is even if you are a great player it is difficult to go out their and consistently win against any professional tennis player. Not to say that Masha's win streak is as good as any (clearly Tier 1 or a GS in their would be better), but it isn't like she's only won two matches.
