Alexandra Eala and Janice Tjen have taken different routes to the women’s top 40, but both began their journeys from a region that is rarely on the tennis map.In January, Eala, who turns 21 the day before Roland Garros starts, became the first player from the Philippines to break into the top 50.Tjen turned 24 earlier in May. When she entered the top 40 in February, she became the highest-ranked Indonesian woman since Yayuk Basuki, who reached the top 20 in 1997 and 1998.While their far-flung countries are more than 1,500 kilometres apart, they share a maritime border. The impact of the sometime doubles partners, not only on the court but in the stands, has brought them the nickname “SEASters”.The huge Filipino expat population flocks to see their first tennis star everywhere she plays.Janice Tjen is the highest-ranked Indonesian woman since Yayuk Basuki in the 1990s.
