Giovanni Mpetshi Perricard v Gabriel Diallo
Every number combines what Giovanni Mpetshi Perricard does well with what Gabriel Diallo allows, each measured against the tour average and shrunk toward it when the sample is thin. Flip perspective
Forecast
Each player's serve and return strength is fitted against every opponent they were charted against, so a record built on weak opponents counts for less. Both were charted enough in the last three seasons, so those carry the most weight. The result is then nudged by Giovanni Mpetshi Perricard's record against Gabriel Diallo's tactical lookalikes and in their charted head-to-heads (lookalikes: +2.3 on serve, +2.2 on return vs expectation (613 points)). A game-by-game Markov chain turns point odds into match odds; the 90% range covers the uncertainty in the two strengths, not the nudges. Charted matches lean toward big events, so treat this as a scouting estimate, not a betting line.
Head to head, per 100 shots
| Career | Giovanni | Gabriel |
|---|---|---|
| Direction choice | −0.26 ±0.07 better than 9% | −0.28 ±0.06 better than 7% |
| Shot selection | −0.11 ±0.24 better than 38% | +0.45 ±0.13 better than 89% |
| Execution | +0.77 ±0.79 better than 90% | −2.12 ±0.74 better than 2% |
| Points left on the table | 3.39 ±0.12 lower than 10% | 2.80 ±0.17 lower than 31% |
Each player's career against an average tour player in the same position, adjusted for opponent strength, with a 90% margin (shots clustered by match). Points left on the table is the gap to the best-value direction for the same stroke, so lower is better. Percentiles are within each player's own tour. A side is highlighted only when the gap is larger than the margin on the difference.
Serve plan
The share of points the server wins when a first serve lands in that direction (hover a rate for its 90% interval; ± is the 90% margin). "Matchup" combines the server's rate with how this returner handles that serve. "Optimal" is the mix that wins most against this returner once they start reading a habit, at the response measured across the tour, and only within the range servers' habits actually vary. The gain over the current mix is how exploitable that mix is.

Return plan
Value of each return, in points per 100 returns against an average return of the same serve (direction, court, surface): the tour's result with that return, the returner's own edge with it, and what this server gives up when it comes back to that side. Returns with no charted direction are left out, so values compare with each other rather than with zero. Depth isn't a choice here: missed returns have no depth. Serve quality isn't charted, so a block through the middle partly reflects the serve that forced it.
