Forgot the lefty splits, look at the fact that over the last 3 years, he has shown to have a consistent walk rate while showing consistent power. His BABIP was low this year due to Valley Fever and he still posted great numbers the last 2-3 months of the season, and had very good HR and SLG numbers. According to Fangraphs, he's poised to post .354 OBP/30 HR's/.500 SLG in 2013. We can easily extend him for 5 yrs/30 mil(3 mil in 2013; 4 mil in 2014, 5 mil in 2015, 8 mil in 2016, 10 mil in 2017), given that's he only made 2-3 mil in his pro career. Sure Ike is 3 years away from FA, but he'll likely make 6+ mil in arbitration for 2014 and 2015, and it'd be wise to lock up players for below market value given this team's finances.
I'd throw in extending Tejada too, given how much short-stops get paid, maybe Murphy too.
