Philipp Kohlschreiber claimed a third title on home soil at the BMW Open, the veteran German overcoming a determined challenge from Dominic Thiem in Sunday's final.
World number 15 Thiem has won more matches than any player on the ATP World Tour this season and was seeking to follow up tournament victories in Acapulco and Buenos Aires earlier this year.
However, the 22-year-old Austrian was eventually beaten in Munich by an opponent 10 years his senior, as Kohlschreiber triumphed 7-6 (9-7) 4-6 7-6 (7-4) in two hours and 32 minutes to enhance his already impressive record at this ATP 250 event.
Kohlschreiber had previously won the BMW Open in 2007 and 2012, before finishing as runner-up in two of the last three years.
There was initial frustration for Kohlschreiber as he saw set points go begging when serving for the opener at 5-4 and 6-5.
He finally prevailed in the subsequent breaker, accepting his eighth set point, but Thiem refused to fold and performed strongly behind his first serve to pull level.
Thiem again showed character when 5-3 down in the final set, breaking Kohlschreiber to love and then saving two match points on his own serve.
However, Kohlschreiber was not to be denied as he came through a second tie-break to prevail, his success sealed with a backhand volley at the net.
