You're assuming that Wood started off with an even number of service years. No, I did the actual maths. Or I tried to. He was at 1 year, 39 days coming into the season. He was kept down until May 22. If I'm doing the maths right, he will miss cutoff for another year by a few days. AZ Phil was saying, a few days ago, that Wood should have been kept down at Iowa for 4 more days to gain another year before he'd be a free agent. He thought the Cubs should have sent Wood to the minors this past Saturday, pitched at Iowa earlier tonight, then recall him on Tuesday. That would have bought them the extra year of service time. http://www.thecubreporter.com/2012/07/05/obligatory-thread-overflow-post#comments (check his multiple comments)
