Mika Stojsavljevic faces Marta Kostyuk in the London WTA 1/16-finals on grass on 8 June, with a best-of-three match setting up a clear ranking gap.

Kostyuk arrives as the heavy favourite, backed by stronger recent results and a much sharper return game. Stojsavljevic has shown useful grass-court serving numbers, but the wider data makes this a hard first-round test.

Stojsavljevic brings grass serve strength

Stojsavljevic has gone 2-1 on grass this season and has held serve in 85% of her service games, which gives her a clear route to staying close early. The concern is the other side of the ball. A 24% return-games-won rate leaves little room for loose service games against a player who has been breaking far more often overall.

Recent form strongly favours Kostyuk

Kostyuk has won nine of her last 10 matches, while Stojsavljevic is 4-6 across the same span. That gap matters because Kostyuk has also won 53% of return games recently, a figure that can quickly turn scoreboard pressure into control. Stojsavljevic's 76% hold rate in that run is solid, but her 30% first-set win rate is a warning.

Bookmakers see a clear gap

Bookmakers price Kostyuk at 1.08 against Stojsavljevic at 8.00, with first-set prices of 1.14 and 5.50. That is a firm market view, not just a narrow lean.

Return pressure is the main test

This match looks likely to turn on whether Stojsavljevic can protect enough service games to make Kostyuk uncomfortable. Her serve numbers on grass are useful, and her recent ace average gives her some cheap-point potential. But Kostyuk's return form, broader season record and lower recent court time over the last three matches all point the other way.

Predicted Winner

Mika Stojsavljevic

The data points clearly towards Kostyuk, mainly because of her recent 9-1 run, strong return numbers and overwhelming market support. Stojsavljevic's grass-court serve gives her a chance to keep parts of the match tight, but Kostyuk has more ways to create pressure.
