Berdych has often flattered to deceive but the way the Czech dealt with Ferrer, who is a relentless athlete, made Mats sit up and take notice.
Perhaps now Berdych is ready to make a sustained challenge against the sport's great names...
In the women's draw, the big shock was the victory of teenager Eugenie Bouchard against Ana Ivanovic.
Mats said he was taken aback by Bouchard's maturity as she came from a set down to win 5-7 7-5 6-2.
Bouchard also joined GS&M in the studio to discuss her brilliant run to the last four of the competition.
Li Na is next up for Bouchard in the semi-finals, and Mats has taken note of how the Chinese star has improved and improved as the tournament has worn on. Now she has a good chance of winning the title.
