The Cubs did lose to the Rays tonight 5-4 after another comeback attempt in the 9th inning against Percival. The big news from tonight was that Carlos Zambrano was taken out in the 7th inning with right shoulder discomfort. He’ll be flying back to Chicago tomorrow to have an MRI done and said at his press conference he was already feeling better. So maybe it’s nothing to worry about. But what if it is?
There’s no point in trying to figure out what is wrong and how long he may be out since we simply do not know. Let’s say he’s out for the rest of the year. I ran some numbers a bit ago to see how much damage that would do to the Cubs and how it might affect their playoff hopes.
I used the Marcel projections, which are done by Tom Tango. I had, prior to the season, calculated pitcher WAR, but couldn’t easily locate the file so just did it again. Carlos Zambrano was projected as a 4.05 WAR player. That’s 4.05 Wins Above Replacement. We’ve played 44% of the season so over the final games this year, Zambrano would be expected to produce 2.27 additional WAR. So if Zambrano were out the rest of the season we wouldn’t get that production from Zambrano, but we would get some production from whoever replaced him.
There are a few options. Sean Marshall is probably the most likely followed by Jon Lieber and Rich Hill. I’m not even including Kevin Hart partly because Marcel projected him as a reliever, but mostly because he just plain sucks and I don’t want to see how ugly the numbers would be. Below is the projected WAR for Lieber, Hill and Marshall.
Rich Hill: 2.68
Jon Lieber: 1.08
Sean Marshall: 1.29
Lieber was projected to only throw 114 innings and Marshall 122. Rich Hill was projected to pitch 165 innings.
90 games left. That’s about 16 starts for the 5 starters. 6 inning average per start. That’s 96 innings. Readjusting those 3 WARs for playing time gets you the following:
Rich HIll: 1.56
Jon Lieber: 0.91
Marshall: 1.02
Each of those 3 pitchers, if allowed to make 16 starts and throw 96 innings, could realistically be expected to produce at that level. Obviously Rich Hill is the best option, but he’s lost all control of the strike zone so those numbers don’t mean a whole lot at this point. Sean Marshall is the next best option and the most likely option.
As mentioned earlier, one could expect Zambrano to be 2.27 WAR the rest of the way and we can reasonable expect Marshall to be 1.02 WAR from this point forward. My handy dandy calculator tells me that’s a difference of 1.25 WAR. So whatever was true about this team before the game today, it’s still true. A little over one win less than we would have had were Zambrano healthy (and he may still be, but this is just an exercise). But there is Zambrano’s offense compared to whoever replaces him. It’s hard to know exactly how much more, but I’d guess probably about half a win, tops, over the rest of the season. So maybe closer to 1.75 less wins. Thereabouts.
So worst case scenario is that Zambrano is out the rest of the season and we lose an additional 1.75 games. Or, in other words, 1-2 games. I think most of us would have said the Cubs would likely win between 91-95 games prior to today. Losing Carlos Zambrano, if that’s in fact what happens, will suck, but if we were that good before his loss, we’ll end up winning 89-94 games. Still pretty damned good.
