Winning the New Zealand championships gained Tearney a wild card entry into the qualifying draw for the
2019 ASB Classic, where he lost in the first round to
Thomas Fabbiano. A few weeks later he was in Portugal where, in an epic match with more than a dozen rallies of twenty shots or more, he beat Jacob Grills in the final of the ITF Futures tournament in
Vale do Lobo. Tearney was called up to the
New Zealand Davis Cup team in March 2020 for their tie against
Venezuela, despite no longer playing tennis professionally and working for a property development company, and defeated
Jordi Muñoz Abreu in the first singles rubber in straight sets 6–4 6–4. ==Challenger & ITF Tour Finals==
