Some fun details on this situation coming out of Chicago...
1) The last two years of the contract have options. No one's quite sure if they are player, team, or mutual, but he's guaranteed six years with the Cubs.
2) According to an interview with Piniella, the Cubs intend on playing him at one of the corners. He said the team intends to pursue starting pitching and a center fielder now, so I'm guessing that means Murton or Jones gets moved. Some people think Jones might move to CF, but that seems unlikely.
3) The Cubs reportedly were upping their payroll up to $120m this offseason. With this signing, the current payroll is at around $100m.
4) There also is reportedly a no trade clause that lasts for 5-6 years.
