Justin Verlander might become the first $200 million pitcher. Max Scherzer already is due a hefty raise in arbitration. And while Miguel Cabrera and Prince Fielder are locked into long-term deals, there's another potential cornerstone the Detroit Tigers are going to have to worry about in the near future. Center fielder Austin Jackson isn't eligible to be a free agent until after the 2015 season, but what's his worth going to be? "At age 25 and in his third season as a big leaguer, Jackson showed that he had become a complete player who offers Gold Glove-caliber defense, hits for average (.300), gets on base (.377 OBP) and hits for power (55 extra-base hits). Andrew McCutchen's six-year, $51 million contract extension might be a good comp for what a Jackson extension might cost the Tigers," wrote ESPN.com's Jason Martinez. Martinez is examining the "window of contention" for each team. As you'd imagine, that's 2013 for the Tigers. He's also noting players who are coming up for new contracts in the coming years. And that includes Jackson. So what about his McCutchen comparison? McCutchen, in his fourth season in 2012, hit .327 with 31 home runs and 96 RBI and finished third in the National League MVP voting.
