Francisco Cerundolo has become only the second Argentine to reach the Queen's Club Championships final as he battled past Alex de Minaur's conqueror Brandon Nakashima in three tough sets.
For the third time in his four matches on the grass this week, Cerundolo was taken to a deciding set but again stayed composed to prevail 6-7 (5-7) 6-3 6-4 on Saturday and set up a final against 2024 champion Tommy Paul.
American Paul, who never got the chance to defend his title last year because of injury, beat Frenchman Ugo Humbert 6-3 6-3 in the other semi.
Cerundolo confessed this week to never having played on grass before turning professional but the 27-year-old seventh seed showed the surface holds no fear for him as he edged past Nakashima, who'd knocked out top seed de Minaur in the quarters, in two hours and 43 minutes.
