Yes, this SA and India series looks like completely fixed. All match results are unexpected. Some this is fishy don't bet more on these matches.
whether the matches are fixed or not, what to do , we want to earn money from this matches. next match that is 4th odi between India vs South Africa , the winner will be India, then the series will become more interesting.
Yes, agreed with you that if India wins the next match then series will be more interesting. fifth match will be series decider and it will be a big final. Result of the first three matches were really unpredictable but I don't agree that the matches were fixed, India and South Africa are top teams in the world and its impossible to fix the matches as they have some great players and its bad to raise a question on their spirit of sportsmanship.
I also think in 4th odi match India has great chance to win to make this series level, when we look at this trend than it seems India will win this match and take this series to level and than 5th match will be link final match and will be more interesting.
I think toss will be very important for the next match. As per the trend in this series you can see that the team who won the toss has elected to bat first and the other team has always failed to chase the target. If the same trend continues then both the captain will go for bat first so the toss will be very crucial for the remaining matches.
