RIGA, Latvia (AP) — Giannis Antetokounmpo scored 29 points and his younger brother Kostas blocked four shots as Greece beat Lithuania 87-76 to reach the EuroBasket semifinals on Tuesday.

The Milwaukee Bucks star’s clutch free throws in the final minute helped Greece seal the victory to set up a last-four matchup with Turkey.

Antetokounmpo sank two free throws to give Greece a 10-point lead with 19 seconds left after Lithuania had cut Greece’s 16-point fourth-quarter advantage in half. He had made two other free throws with 47 seconds on the clock.

Kostas Antetokounmpo’s four blocked shots all came in the first half. The 27-year-old center plays for Olympiakos. Vasileios Toliopoulos scored 17 points for Greece.

Greece is a two-time EuroBasket champion, having won the tournament in 1987 and 2005.

Jonas Valanciunas led Lithuania with 24 points and 15 rebounds.

Sengun stars as Turkey beats Poland

Alperen Sengun’s triple-double helped unbeaten Turkey to a 91-77 win over Poland. The Houston Rockets forward had 19 points, 12 rebounds and 10 assists in an entertaining performance.

With his mother in the crowd, Sengun made a one-handed pass the length of the court to Sehmus Hazer, who dunked and gave Sengun a thumbs up late in the second quarter.

Sengun found Hazer again with a spinning no-look pass in the lane in the third quarter and then treated himself to a one-handed reverse dunk with the game in hand.

Turkey pulled away to lead 46-32 at halftime after Poland’s physicality on defense and its bench presented early problems.
