Aleksandra Krunic defeated Heather Watson 7–6, 6–4 in the first round of the WTA 250 Birmingham tournament on grass on 16 June 2015, an upset victory that defied the pre-match odds favouring Watson at 1.37 to Krunic's 3.34. Krunic's composed performance on the grass court, particularly her ability to secure the opening set via tiebreak, proved decisive against the higher-seeded British player. The Serbian's clinical execution in the second set, where she broke Watson's serve and held firm to close out the match, demonstrated her capability on the surface despite entering as the outsider. The result represented a significant scalp for Krunic and suggested Watson's grass-court form may have been vulnerable heading into the latter stages of the season.
