The American lost to Brazilian star Joao Fonseca<\/a> in the final 12 months ago but will aim to go one step further on Sunday when he meets 20-year-old Belgian Alexander Blockx<\/a>. Returning to Jeddah as the top seed this year, Tien is the second man in tournament history to reach multiple finals at the event, joining World No. 7 Alex de Minaur<\/a> (2018-19).<\/p>\n \u201cI won the first and had chances in the second before he just ran away with it,\u201d Tien said of his final defeat to Fonseca last year. \u201cI will try not to let that happen tomorrow\u2026 I know Alex has been playing great this week, so I\u2019m really excited.\u201d<\/p>\n World No. 28 Tien arrived at the 20-and-under tournament as the strong favourite after a standout year, highlighted by his first tour-level title at the 250 event in Metz. However, he suffered a stuttering start to his campaign when he lost to Rafael Jodar<\/a> in five sets in his round-robin opener.<\/p>\n With the pressure on, the lefty responded with wins against Martin Landaluce<\/a> and Nicolai Budkov Kjaer<\/a> and was in control throughout the 75-minute semi-final encounter with Basavareddy, who received two medical timeouts for a deep cut on his finger.<\/p>\n In a controlled performance, Tien displayed the level that earned him five Top 10 wins in 2025, according to the Infosys ATP Win\/Loss Index. He recovered from dropping serve in the opening game of the first two sets, dictating the tempo with clean baseline ball-striking. The 20-year-old committed six fewer unforced errors than Basavareddy (19-25) and struck at the right moments to prevail. Tien will play Blockx on Sunday at 8pm local time.<\/p>\n<\/a><\/p>\n
