In comparison to his recent match against CCA Zhang played a lot better strategically. If you saw his match against CCA in the Korean Open this year, you could notice several things: an overall lack of interest and motivation and as a result giving cheap points to CCA. Zhang not letting CCA move much, mostly playing in his comfort zone (middle of the table and FH, but not enough in the deep BH or FH). Serves were not placed or varied much, giving CCA the opportunity to instantly put pressure on Zhang without moving much. His overall level of play wasn't that bad, just his tactics weren't on point.
I haven't seen the whole match today, I tuned in in the middle of the third set. But some things were noticable: Some vocal reactions from Zhang when scoring a critical point, which was refreshing to see. Also better placed serves short FH, half long FH or middle of the table, forcing CCA to play the banana flick from there and then instantly putting pressure on CCA's BH with a BH down the line or a good placed FH. Zhang used his speed to his advantage. When comparing the two of them, CCA is slower especially coming from the short FH to the deep BH. Jike's BH was very good today, so this was like his bread and butter in the last two sets of the match. Overall, I don't think CCA had a lot of opportunities today. Jike played well on the critical points, thus giving him a logical 4-0 victory.
It certainly wasn't the best Zhang Jike we've seen, but he played much better than in his previous matches. His performance was good, not spectacular like Ma Long yesterday, who showed everyone that he is the player to beat here. I am very curious as to what the next few matches will bring for Jike.
