Ohhh....... What a score

Just happened to see the scoreboard of the Mumbai (vs) Baroda ranji trophy semifinal match. What interested me in this news is the fact that the score card read 5-0 during Mumbai's second innings. Anyone who follows cricket would understand that it is normal to have a score of five for no loss at the beginning of an innings. The interesting part is that it is actually zero for five wickets. The top 5 batsmen of Mumbai scored a duck!!!! The other fascinating thing is that Mumbai went on to win this match. Is it that the ranji matches have become so competitive or is it because the standards have fallen so much? Knowledgeable folks, please help me out.
