In the ATP Challenger Split semifinals on outdoor clay, No. 269 Sascha Gueymard Wayenburg faces No. 248 Tom Gentzsch, both 22-year-olds showing sharp form with straight-sets quarterfinal wins Friday—Gueymard defeating Andrej Nedic 6-1, 7-5 after routing Jacopo Berrettini, while Gentzsch crushed Alexander Vasilev 6-0, 6-2 following a 7-6(?), 6-0 upset of seed Filippo Romano. Gueymard leads their head-to-head 1-0 (6-3, 6-1 indoor hard, Helsinki Challenger last November), but clay suits both: Gueymard 42-35 lifetime (54.5% win rate), Gentzsch even stronger at 114-72 (61.3%). No reported injuries or withdrawals; surface favors baseline grinders amid mild Croatian spring conditions.
