A strong all-round display by George Linde was not enough as South Africa A slipped to a two-wicket defeat India in their second one-day match in Trivandrum on Saturday.
The result means the tourists fall 2-0 behind in their five-match series.
The Cape Cobras man first thrashed an unbeaten 52 off 25 balls (1x4, 5x6) to help the tourists post 162/5 in their 21 overs.
Linde then bagged 1/21 in three overs, but it was not enough as the hosts completed the victory with one over and two wickets to spare.
Ishan Kishan thumped 55 off 24 balls (5x4, 4x6) to wrap up the win.
