At the age of 14, nine years after he first began playing tennis, Ruusuvuori entered his first ITF Juniors tournament, the Nokia Junior Cup, in 2013. 2014 offered his first success, reaching two singles finals, two doubles finals, and winning two doubles titles.

He continued his doubles success as well, winning three events and reaching the finals of two more.

After not seeing competition in April, Ruusuvuori returned in May, participating in the Italy F13 Futures event, where he lost in the third round of singles qualifying. He then competed in the 58th Trofeo Bonfiglio junior event, losing in the first round of both singles and doubles.

Competing as an unseeded player at the US Open in September, Ruusuvuori saw his best singles Grand Slam result of the year, reaching the semifinals. En route, he defeated two seeded players: 13th seed Sebastian Korda of the United States in the second round and 10th seed Sebastián Báez of Argentina in the quarterfinals. In the semifinals, Ruusuvuori lost to eventual champion Wu Yibing of China in three sets, 6–4, 3–6, 6–7, after having two match points.
