If you want to make sure there is only one value printed (like a implicit |uniq) you need to quit after the first match:

Code:
sed -n '/^Rows:/ {;s/^Rows:[^0-9]*\([0-9][0-9]*\).*/\1/p;q;}'

This will print the first line starting with "Rows:" and leave sed after printing it. I have tried to improve the regexp so that (variable numbers of) blanks before and behind the number eventually get deleted too.

I hope this helps.
