Center Court opens at 12:00 pm CEST with the opening semifinal. Expect the second singles match to roll into the mid-afternoon. Doubles action sits on deck not before 3:30 pm. Stuttgart runs on fast local time, and the order stays strict unless weather intervenes.

Injury Updates & Team News

All four semifinalists come through their quarterfinals without fresh injury flags. Shelton battled through a rain-delayed, three-set thriller. Fritz survived two straight three-set scares. Lehecka and Bublik looked sharp in straight-sets wins. Everyone appears ready to go.

Key Player Battles

Shelton’s massive lefty serve and explosive athleticism against Lehecka’s smooth movement and steady baseline construction. Lehecka reached the Queen’s final last year and knows how to blunt big weapons on grass.

Fritz’s heavy serve and proven big-match experience on this court versus Bublik’s variety, creativity and ability to disrupt rhythm. Bublik loves throwing in the unexpected on fast surfaces.

Head-to-Head Records

Shelton leads Lehecka 2-0 overall, including a win on grass. The American has taken every set in those meetings.

Fritz and Bublik share a tight rivalry. Bublik holds a slight 4-3 edge in their head-to-head, though Fritz has won important recent encounters. Expect plenty of tiebreaks and service holds.

Match Prediction

These should both go the distance. Shelton’s raw power and improved grass movement give him the edge over Lehecka in three sets. Fritz’s experience defending this title and his comfort on the surface should see him through a tight battle with Bublik, also in three sets.

The winners will meet in Sunday’s final with Wimbledon looming just weeks away.

Fritz chases back-to-back titles in Stuttgart after claiming the crown last year. Shelton hunts his first ATP 250 final on grass. Lehecka looks to reach his second straight grass-court final after last year’s Queen’s run. Bublik aims to snap a recent skid and reach his first Stuttgart final.
