Keys M. vs Samsonova L. prediction

in quarter finals of wta berlin keys will play against samsonova. my prediction in this match is that will keys win in straight sets. she is in decent form, with huge win over sabalenka, very good serve which is important for grass, good return and excellent play from baseline. on other side samsonova manage to win 4 in row with very good game but her opponents played under their real quality and keys is much better. to sum up keys is better player and i expect easy win in two sets
