A right-arm medium-pace bowler, she played eleven One Day International (ODI) matches, including games at the 1988 World Cup.
Born in Amsterdam, Loman made her debut for the Netherlands in its first ODI, a one-off game against New Zealand for the 50th anniversary of the Nederlandse Dames Cricket Bond.
Loman's matches during that period including an unofficial Test against Ireland, played over three days in July 1987 at the Sportpark Klein Zwitserland in The Hague.
She led her team's bowling averages, and with Ingrid Dulfer-Keijzer was the equal leading wicket taker for the Netherlands.
Her last ODIs were played at the age of 30, at the 1991 European Championship, where she took 2/36 against Denmark, 1/47 against England, and 1/8 against Ireland.
