Andrey Rublev continued his winning buildup to the French Open on Saturday as he beat Casper Ruud 6-4, 6-2 to reach the Hamburg Open final.

The Russian hit four aces on his way to winning in 1 hour, 23 minutes against Ruud, who has the most clay-court wins of anyone on the ATP tour this season with 15.

Rublev advanced to his third career clay final and seventh overall. Now 24-6 in tour matches this season, he equaled his achievement of reaching the final in Hamburg last year when he lost in three sets to Nikoloz Basilashvili.
