Osuigwe carries momentum from a 13-11 YTD record, splitting recent clay results with a comeback win over Dalayna Vidmanova on April 14 but falling to Sinja Kraus three days later in Oeiras qualifiers. Teichmann, a former clay standout with Madrid SF and Rome QF runs, has limited 2026 play (1-1 YTD per WTA) after a qualifying loss to Anouck Vrancken Peeters on April 13, amid past back concerns now cleared. No late withdrawals or injury reports; mild Portuguese spring weather favors baseline grinders.",
