Johanna Larsson

Against an average opponent

Serve and return points won, refitted against every opponent at once so a record built on weak or strong opposition is put on the same scale. Career, all surfaces, with a 90% margin. Raw is the plain share of points won.

Value per 100 shots

Points gained per 100 shots compared with an average tour player in the same position, adjusted for the strength of the opponents faced, with a 90% margin (shots clustered by match). Raw is before the opponent adjustment. Built on 2,626 shots.

Shot expected value

The share of points Johanna Larsson goes on to win after each option in the positions they face most often, shrunk toward tour average when the sample is small. Showing the 8 most-used options; teal marks the best one with at least 30 shots.

Serve under pressure

Pressure predictability index −4 How much less varied Johanna Larsson's first-serve direction gets on break points. Positive means easier to read. Based on 73 break-point first serves.

Is the serve mix in equilibrium?

Game theory says a well-mixed server wins equally often with every direction they use. If one direction wins more, it's underused and points are being left behind. This is the minimax test Walker and Wooders ran on Wimbledon finals, applied to every charted first serve. Win rates include faults. "Optimal" allows for returners reading a habit. A direction loses 0.19 points per 100 serves for every 10 points of habitual usage, measured from WTA servers whose mix drifted between matches. Shifts stay within the range servers' habits actually vary, the only range that response was measured over.

Exploitability 0.54 points per 100 first serves What the optimal mix would win over the current one, both courts. More exploitable than 100% of WTA servers. Tested on matches they weren't fitted on, WTA mixes picked this way win 0.42 per 100 first serves on average.

Repeating the previous direction to the same court: +0.8±8.7 points per 100 against switching. Negative means returners read repeats. Tour-wide, repeating costs women about 0.4 points per 100 and costs men nothing, so men's returners don't measurably anticipate direction. (166 repeats, 266 switches.)

Signature patterns

Recurring sequences that win more than Johanna Larsson's own baseline, ranked by edge weighted by how often they're used.

Discovered sequences

Mined from every me → opponent → me run of three shots, with no templates. Ranked by how much more often Johanna Larsson wins the point once the sequence happens, weighted by how often it happens. Think of them as chess openings.

2. FH crosscourt → FH through the middle → BH through the middle used 1.2% · won 42% · +7.3±12.6 vs own baseline · +6.1 vs tour on the same sequence Disrupted by Mona Barthel (3/6), Kurumi Nara (3/6)
3. BH crosscourt → BH through the middle → FH crosscourt used 1.1% · won 41% · +5.9±12.7 vs own baseline · −3.9 vs tour on the same sequence Disrupted by Kurumi Nara (2/6)
4. BH crosscourt → BH crosscourt → BH through the middle used 1.3% · won 38% · +3.1±12.1 vs own baseline · −1.8 vs tour on the same sequence Disrupted by Kurumi Nara (2/8)
5. FH crosscourt → FH crosscourt → FH crosscourt used 2.4% · won 37% · +1.9±10.3 vs own baseline · −10.0 vs tour on the same sequence Disrupted by Kurumi Nara (2/6), Agnieszka Radwanska (3/6)
6. FH crosscourt → FH through the middle → FH through the middle used 1.2% · won 37% · +2.5±12.3 vs own baseline · −4.6 vs tour on the same sequence
