Since nothing new was posted today, I thought I'd briefly mention a Tribune article which states that Jeff Samardzija will get a shot at starting in 2009. According to Paul Sullivan of the Tribune, whose article is linked in the previous sentence, it's his gig to lose.
Unfortunately for him, there's a lot of politicking involved in any decision. If he wins the role, the Cubs probably won't have room for Angel Guzman, who's likely to be cut. If he loses the role, he can be sent to Iowa where he'll get to hone his craft while other guys who want to be a starter will continue to get their chance.
I'd have to say that Shark would need to out pitch his rivals by a wide margin to actually start the season in the rotation. But as I posted earlier this past week, he'd be my first choice unless he lost it by a wide margin.
