Let's have some fun with numbers! Kevin Gregg in 2008 BB/9: 4.85 K/9: 7.60 HR/9: 0.39 H/9: 6.68 Carlos Marmol in 2008 BB/9: 4.23 K/9: 11.75 HR/9: 1.03 H/9: 4.12 Kerry Wood in 2008 BB/9: 2.44 K/9: 11.40 HR/9: 0.41 H/9: 7.33 Bob Howry in 2008 BB/9: 1.66 K/9: 7.51 HR/9: 1.66 H/9: 11.42 I'm comparing Gregg to those three because they were the three most used relievers by the Cubs last season. While these numbers are not perfect evaluators (H/9 especially), they provide a helpful baseline that supplements a lot of what we saw over the course of last season. For example, it should surprise no one that Wood and Marmol struck out batters at an unholy rate last season. Gregg's best attribute is the ability to keep the ball in the park. He also doesn't give up a whole lot of hits. However, he has a worse problem with walks than Marmol. Unlike Marmol, he doesn't strike guys out. Essentially, I'm seeing a guy who gets himself into jams by giving up a bunch of walks, but gets out of them through putting the ball into play rather than through striking guys out. That's a bit worrying. My stance on the trade is this. I've liked Ceda since the Cubs got him in the Todd Walker trade, but I've also realized that the guy has a bit of an injury history and may not be able to harness his command and control effectively. I'm a bit sad to see him go, but he's expendable. I'm more upset that we actually acquired Gregg. I don't see a whole lot to like.
