Hello, I'm Pinethicket. I noticed that you made a change to an article, Tennis ball, but you didn't provide a reliable source. It's been removed for now, but if you'd like to include a citation and re-add it, please do so! If you think I made a mistake, or if you have any questions, you can leave me a message on my talk page. Thank you. Pinethicket (talk) 21:01, 20 December 2012 (UTC)
