Wuertz has been walking a lot of guys this year, and he just gave up 3 more in his last outing. I can see why they'd hesitate to bring him up. Between Samardzija and Ceda, I'd probably prefer Ceda. However, that requires adding Ceda to the 40-man, and likely means burning an option when they send him down in a few weeks. This could be a setback to Samardzija's development, however, to equate it to the stupidity of signing Neifi Perez is just plain wrong. He's over the 110 IP mark right now and he threw 140 last year. Even if he comes up and stays in the major league bullpen through the end of the year, it wouldn't be hard for him to match that 140 level, giving him back to back solid totals for a guy still learning to pitch. He's been in the bullpen off and on a couple times the past two years, show there shouldn't be much of an adjustment. I think the Cubs still view him as a front end starter longterm, so I doubt there's a lot of risk they will keep him locked into the bullpen - unless he pulls a Marmol, in which case I can't say I'd be disappointed. If he comes up and struggles, then you send him back down in early August and he still gets enough minor league starts to have 140-150 IP for the year. And at that point you have Lieber coming back, hopefully Wuertz figuring it out, and maybe Howry finally improving. I don't see a lot of downside to calling him up.
