It will probably do you more good than harm. First of all, a competitor should spur you on to work hard on your product, lest everyone picks your competition instead.

Secondly, you can use it as a real marketing opportunity. What I mean is, with a product from Yahoo, there's going to be all sorts of press and many cricket fans talking about their product. That's your cue to show up (without being spammy), and get the word out about yourself. You could get some media attention at the very least, as well as word of mouth (people talking about Predictopus will be told by their friends about doosracricket).
