I saw the bat signal! Polanco's issue with options actually dates back to 2010. 90 days is the threshold for a "full season" when calculating for a potential 4th option year. All of the rookie league seasons are less than 90 days long, so generally rookie league assignments don't count as "full seasons." But while Polanco technically spent the whole 2010 season in rookie league ball, he actually split it between two rookie leagues -- an early starter and a late ender -- and thus he spent 92 days on an active roster that year. For comparison, Vargas and Kepler both signed the same summer as Polanco (2009), and both were added to the 40-man roster at the same time too (November 2013), but they both qualify for a 4th option this year because neither played a "full" minor league season prior to 2013. They've already used all 3 of their options, and have only 4 "full" pro seasons total. Thanks to 2010, Polanco has 5 "full" seasons and thus does not qualify. So Polanco's usage in 2014 and 2015 did not matter, as far as his options were concerned. He basically burned options both of those years when he was assigned to the minors out of spring training. The only alternative for the Twins at that point to conserve his options were to either leave him off the 40-man roster and exposed to Rule 5 draft, or to keep him in MLB for virtually the whole season. The problem was 2010. Maybe it's not a big problem -- he's more or less ready to stay in MLB in some capacity now -- but it is an odd one that limits our flexibility. I'd be curious to hear what happened in 2010 that Polanco split the season between two rookie leagues. He started in the Dominican Summer League, then moved to the Gulf Coast League -- did they want to quickly get him out of the Dominican for some reason? Even so, I think it would have been possible to assign him back to DSL late in the season on paper, and he wouldn't even have had to report there, and that would have ended his season a little early and kept him under 90 days active. Seems like a pretty big oversight for a guy who was a pretty well regarded international signing (Polanco's $775k bonus in 2009 was actually a Twins record for a few days, until Kepler signed for $800k and of course Sano a few months later), especially considering he stayed in rookie league ball for 2011-2012 too (he wasn't on a fast track like Sano). As always, the Cub Reporter web site offers a great read on the fourth option year rule: http://www.thecubreporter.com/book/export/html/3521
