POLAND CLAIM FIFTH WIN
Poland had to work a lot harder to claim their fifth success, a 64-60 Group F win over Latvia.
Karolina Pobozy, who is pouring in 15.2 points and grabbing 9.8 rebounds per game, had 22 and 10 against the Latvians.
Latvia battled back from a 13-point deficit early in the fourth quarter and closed the gap to 63-60 on a jumper by Digna Strautmane with just 56 seconds remaining.
The Poles held their nerve.
Latvia's Kitija Laksa missed two potential game-tying three-balls as Poland held on.
"It was a tough game because of the big difference in heights," Latvia coach Mudite Zandere said.
"Our main point guard was injured and also one of our centers got injured during the game.
"At the end, we missed out on couple of shots.
"I praise the girls for fighting until the end. Our team has character.
"We'll continue fighting."
Both Finland and Poland have sealed places in the Quarter-Finals.
The Latvians are 2-2 and face Luxembourg (1-3) on Wednesday.
Belarus (0-4) fell to Luxembourg 85-69 on Tuesday with Lisa Jablonowski doing a little bit of everything for the winners.
She finished with 26 points, 10 rebounds and four steals - all team highs.
"We had some trouble in the beginning of the game," Luxembourg coach Thierry Kremer said.
"I guess we were not really ready to play and perhaps took the game too easily.
"After the break, we came back and we were ready to play.
"This is such a young team and you can see, they play with their hearts."
