While Andhra trounced Gujarat by nine wickets to notch up its fifth straight victory, Mumbai won its fourth game to make sure of advancing.
K S Bharat with an unbeaten 106 (132 balls, 4X4, 4X6) and Ashwin Hebbar (99, 108 balls, 11X4, 2X6) helped Andhra steamroll Gujarat reaching the target of 251 in 45.2 overs.
Meanwhile, Mumbai rode on half-centuries by Surya Kumar Yadav (71), Prithvi Shaw (53) and captain Aditya Tare (59) to post a four-wicket win over Goa.
Shaw,who led India to a memorable triumph in the under-19 World Cup in New Zealand recently, put Mumbai on track with a well crafted half century.
