Harimoto – Boll: experience matters

The 2017 ITTF World Tour Platinum China Open will always be remembered because of the “Chinese issue”. However, the event of not having any Chinese player competing since the Round of 16 brought us an exciting and totally unpredictable tournament.

It was in the Semi-Finals when one of the most expected matches happened. Tomokazu Harimoto, the Japanese sensation faced Timo Boll, who was already World’s number 1 when his opponent was born, 14 years ago. A difficult match for both of them, as it was their first official encounter and it was hard to place any bet.

In this article, we will analyze the match as usual, revealing the numbers behind, showing some graphs and charts and casting some light on the tactics that Timo used to deactivate the player of the moment.

The match

The result: 1-4 (11-6, 9-11, 8-11, 10-12, 5-11) for Timo Boll seems an easy match. Nonetheless, it did not develop in such a way, as Harimoto had chances to win it most of the time.

The Japanese player started the match with his typical aggresive style, taking the initiative with the backhand and finishing with strong forehand topspins. Boll seemed to have trouble adapting to that game speed and made five unforced mistakes. Moreover, he failed to return three serves, something totally uncommon on him. A result of 11-6 for the Japanese player allowed him to start leading the match.

The second set had a similar fashion: Harimoto attacking and winning points with well-placed forehand topspins. However, Boll managed to find confidence with very spinny first-attacking balls that completely disturbed Harimoto, who seemed not to be used to them. The youngster made seven unforced mistakes that allowed Boll, even with three more service return failures, to take the second set 9-11 and tie the match.

A leading 5-1 for Harimoto in the third set ended up being benefitial for his opponent. Boll managed to comeback and Harimoto used his timeout when 6-5. However, it did not work much, as Boll found the way to make Harimoto move and his footwork was not good enough to reach the balls in the proper moment. Furthermore, Boll’s variation on his service provoked four return mistakes on Harimoto and he recorded an 8-11 to lead the match 1-2.

The fourth set of the match for sure taught Harimoto many things for the rest of his career. He lost the set after being 8-1 up and suffered a German “tornado” who got the initiative in most of the points and did not let him react at all. Even with 10-8 for Harimoto, Boll kept attacking and the Japanese failed to block two spinny topspins. In the end, 10-12 for Boll who avoided a very close 2-2 in the set score to reach 1-3 instead.

The fifth and last set showed us a surrended Harimoto who was physically and mentally consumed by a constant and precise Boll. The young Japanese gambled with several difficult shots – specially serve returns – from which he failed most of them and gave a 2-6 advantage to his opponent. As it had happened during the rest of the match, Boll kept playing smart when pushing and waiting for the most appropriate ball to attack. An ending 5-11 finished the match and Timo Boll booked a slot in the Final where he would play against his mate Ovtcharov.

The analysis

Let’s begin with some rough numbers:

numbers

Although the match result was 1-4, Boll only won 8 points more than Harimoto. Moreover, the German player made much more forced mistakes than Harimoto, which even being 13 years old hit the ball stronger than Boll. However, this fact made him commit more unforced errors: 8, exactly the total points difference they had.

The way that Harimoto plays affected the length of the points and therefore the match. If we check the rally length evolution of the match, we have:

rally_length_with_sets

As can be seen, the average hits per point is close to 4. Just as a reference, Boll had a rally length average of 5.4 in his match against Ovtcharov that we analyzed some time ago. It is also remarkable the amount of points that had only two hits – 20 – which shows the impact of the serve during the match, with many return mistakes from both of the players.

Let’s see now whether the rally length went in favour of any of the players checking the longest rallies of the match:

Rally length Winner
12 T. Harimoto
10 T. Harimoto
9 Timo Boll

8 T. Harimoto

6 Timo Boll

It is obvious that Harimoto controlled most of the longest rallies of the match, which usually make Boll suffer, specially when he is forced to step back farther from the table.

If we take a look at the shot usage during the match…

stroke_usage

Both players have a quite different playing style which is proved with these pie charts. While Boll seeked for his forehand topspin as much as possible, Harimoto trusted his backhand flick to attack short balls. On the other hand, Boll felt comfortable pushing with his forehand, which became the second most used shot.

Compared to previous analysis we have made, the amount of forehand flicks that these two players performed is significantly higher: 22 between both of them. For example, Ma Long and Fan Zhendong only initiated the attack with a forehand flick three times in the 2017 WTTC Final.

Nonetheless, the shot usage stats do not depict how successful the players were. Let’s see it with the following charts:

shot_eff_harimoto

In general terms, Harimoto had a fair distribution of unforced mistakes on all the strokes. The way Boll attacked the ball with a lot of spin and placement variation provoked most of those mistakes. In order to stop Boll from attacking, he forced too much with the backhand flick, making much more mistakes than usual.

His winner shots mostly came, as usual, with forehand and backhand topspins. However, the ratio of errors is quite high on both (32.4% and 20%). Anyway, the worst performer stroke was the backhand block, where he made 9 mistakes on 17 attempts.

shot_eff_timoboll

Timo Boll was generally more accurate. The winners mostly came from forehand topspins, while the majority of mistakes happened when blocking. However, most of them were forced errors. It is outstanding that he had approximately the same amount of forehand topspins than forehand pushes in the table, which denotes how well placed Timo is when playing short, covering the whole table with his forehand.

In fact, this last aspect of the game determined most of the match outcome, as it allowed Timo to attack with higher probabilities of success. The following chart proves it:

winner_by_first_attacker

As we can see, Harimoto wont exactly 50% of the points when attacking the first ball. Seems like a fair number, if Boll’s figures were not so good, as he achieved a 62.16% of points won when he managed to either flick or hit the ball with a topspin before Harimoto.

Was Boll repetitive with his first attacks placement? Let’s analyze it:

first_attack

The first remarkable thing is that he only made 7 mistakes. Apart from that, he seeked more for Harimoto’s backhand, probably after noticing about his weakness when blocking with it.

The keys

All in all, Harimoto was good enough, considering the experience and level of his opponent. However, some aspects of the game were controlled by Boll and ended up making a difference:

  • Harimoto was not consistent enough when attacking, as he made too many mistakes, specially with the backhand flick.
  • Boll felt comfortable pushing short balls and then attacking with very spinny balls, specially to the backhand side of the table, that triggered many mistakes on Harimoto’s backhand.
  • Long rallies, where Boll would have suffered more, almost did not happen, as the rally length was quite short during the whole match. The spin variation and mistake ratio were continuously in favour of Boll.
  • Boll’s comeback in the fourth set severely affected Harimoto’s mood. He surrended in the last set, not even fighting for the match. Lack of experience, physical deficiency, mental tiredness… or a mix of them were the root cause of it.

Future predictions

Timo Boll has been one of the best players in history. Being 36 years old, he is still competing at the highest level. In fact, this year he won the German League with Borussia Düsseldorf, reaching also the Champions League Final and the 2017 WTTC Men’s Singles Quarter Finals.

It was precisely at that stage when Harimoto was knocked out too. While Boll is already thinking about retiring, Harimoto is starting to build a successful future. The latter could at some point reach what the German never did: the World Champion title. We will have to wait to check that. In the meanwhile, we can only compare them at the table, and this time, Boll was the winner.
