Karola Bejenaru is through to the main draw at a $10,000 tournament in Romania while, closer to home, Hilden's Peter Corrie has picked up his first junior world ranking point after both players had impressive wins yesterday.
Eighteen-year-old Windsor player Bejenaru defeated Romanian Alexandra Filip in final round qualifying as she came from 0-3 down in the deciding set to win 6-2 1-6 7-5.
Bejenaru's victory means that if she can defeat Hungary's Lucy Nagymihaly in the main draw today she will earn herself a world ranking point and climb up the ladder.
Corrie followed up his weekend Ulster Junior Open triumph by booking his place in the second round of the ITF junior world ranking tournament in Dundalk.
The 15-year-old was also involved in a close contest as he came from a set down to beat Italian Miguel Romanvello 2-6 6-4 6-4 and he will now face top seed James Davies today.
The McCullough twins, Caitlin and Annie, along with Lucy Octave, also won yesterday in Dundalk but there were defeats for Laura Reid and Emily Beatty.
Caitlin, who won her first Ulster Junior Open title on Saturday, scored a superb 6-2 6-0 win over Lithuanian Emilijn Gedvilaite to earn a date with second seed Megan Davies (GB) in the second round.
Annie was also in fine form as she defeated Germany's Lara Schmid 7-6 6-0 but she, too, has a tough task ahead as she will now play top seeded Dubliner Georgia Drummy.
Octave dismissed seventh seed Maria Povilionyte (Lithuania) on a 6-3 6-2 scoreline, and will meet British player Florence Abbot in the last 16.
Beatty went down 6-3 6-2 to Greece's Anna Arkadianou while Reid lost 6-4 6-3 to Abbot.
