Israel maintained their unbeaten record by overhauling a competitive Estonian total of 154 for three to top the table.
Batsmen dominated the clash between Israel and Estonia at Ropa No. 1, with Nand Lal Riar making a 34-ball 59 and sharing an opening stand of 57 with a patient Mart Tammoja, and Tim Filer making an unbeaten 48 as Estonia put on a creditable 154-3.
Riar also caused the Israelis problems with the ball, snatching two quick wickets as Israel slumped to 7-3. But Eshkol Solomon, who has been their most consistent batsman throughout the tournament, put on 55 with Gabi Schachat and 86 with Danny Hotz to turn the game around, and Israel reached their target with 10 balls to spare and five wickets in hand.
Solomon finished with an undefeated 85, made from 52 deliveries with seven fours and two sixes, while Riar ended on two for 20 from his three overs.
