BOSS OPEN 2026, where to watch and live stream

The BOSS OPEN runs in Stuttgart, Germany from 8-14 Jun, played on fast natural grass. Bounce sits lower than on any other tour surface and points run shorter, which puts a premium on the serve and the forecourt. It is an ATP 250 event. The singles champion takes ranking points and prize money, and a useful chunk of the season prize pool.

The 2026 edition has wrapped. The full results sit below; the recap and the 2027 dates are above.

The grass produces the lowest bounce on tour and the shortest points. The serve does roughly half the work in any match because returners are pulled forward by the skid, and a good first delivery to the body or down the T can be a free point on demand. Rallies above five shots are rare, and the player who serves at high first-serve percentage and avoids unforced errors on the return tends to find himself at break point twice a set without working too hard for it.

Footwork is quieter on grass than on any other surface and over-committing to a corner produces slips and late preparation. Slice stays low and is genuinely difficult to attack, so one-handed backhands and chip-and-charge tactics that look outdated elsewhere on tour remain perfectly viable here. Expect short sets, tie-breaks decided on a handful of points, and the higher-ranked seed to look human against a big server in the early rounds.
