Iga Swiatek is wasting no time implementing changes with her new coach, Francisco Roig. The world number one brought the seasoned coach, known for his long tenure with Rafael Nadal, onto her team just ahead of the crucial clay-court season, signaling her intent to refine her game on her favorite surface.

The pair began their collaboration with intensive training sessions at the Rafael Nadal Academy in Manacor before heading to the Stuttgart Open. In a recent interview, Swiatek revealed that two significant technical adjustments are already underway, focusing on shoring up a known area for improvement: her serve.

"We focused more on the baseline game, but the serve is something that I've been changing quite a lot in my life," Swiatek told Eurosport. "I didn't really feel comfortable with the last movement I had." Faced with the dilemma of making a mid-season change, Swiatek decided that discomfort was a sign to act. "If you feel uncomfortable with something, you can't really continue if you're not 100% in your head, committed to it."

The key change involves a subtle but crucial tweak to her elbow position. "I changed the movement to get my elbow in the back a little bit more bent, which can give me, I think, more speed and more dynamics later on," she explained. While Swiatek's game is built on relentless baseline pressure and phenomenal movement, adding more pop and consistency to her serve could make her an even more formidable opponent, especially on faster surfaces.

Her Stuttgart campaign offers an immediate test for these new adjustments. After a first-round bye, she faces home favorite Laura Siegemund, against whom she holds a dominant record. A potential quarterfinal clash looms with the red-hot 17-year-old Mirra Andreeva, followed by a possible semifinal against power-serving top seed Elena Rybakina. Navigating this tough draw will require Swiatek to be sharp from the start, making her new partnership with Roig and their technical refinements a fascinating subplot to watch.
