Slask Wroclaw exited the EuroCup with their heads held high after an 87-85 win over BC Zadar.
The Polish outfit did well to advance to Round II of the competition but they have been out of sync since.
Tomasz Jankowski's men entered Tuesday's game with just one win and four defeats in this phase.
His two free throws with 1:09 remaining put Slask ahead at 83-81, and they stayed in front the remainder of the game although Robert Skibniewski also had to make shots from the line in the final minute to see Slask home.
Frano Colak did make a jumper with seven seconds remaining to pull Zadar to within 86-85, but they allowed five seconds to tick off before fouling Fletcher and he sank one of two for the final scoreline.
Fletcher finished with a game-high 24 points for the winners.
BC Zadar had an unusual campaign.
They lost their first three games in the opening group stage but then won three in a row to reach Round II.
That fuelled hopes a place in the quarter-finals, but the Croatian team's fortunes changed for the worse when they lost at home to Lokomotiv Rostov on January 17, and followed that up last week with a 92-90 setback at Dexia Mons-Hainaut.
Tuesday's loss meant they finished their EuroCup how they began it - on a three-game losing run.
