How best to handle Soriano's injury?
4 Comments Published by Colin Wyers on Tuesday, April 15, 2008 at 9:25 PM.Let's assume for a moment that he's only going to be out a few days. That assumption means no callups. How best to deal with Soriano's injury? (When I say wins, I mean WAR over a full season.)
DeRosa in left, Fontenot at second?
This should come as no surprise to you - DeRosa is less valuable as a left fielder than as a second baseman - by about half a win. Fontenot, meanwhile, is somewhere between 1 to 1.5 wins worse than DeRosa at second.
Ward in left?
Ward is below replacement as a left fielder, given his atrocious defense in the outfield. In fact, the more I think about it, the more I don't like having Ward on the team. He makes the bench seem a lot shorter than it really is.
Johnson in left?
Probably the best option; it's, after all, why teams carry fourth outfielders. That means keeping Pie in the lineup, however, which the team has seem reluctant to do so far this season.

Let's take a look at the accumulated press reports and see if we can't divine what Lou's plans are for the day, shall we?
- Henry Blanco will start. Soto's a young guy, but he hardly leads the team in days off at this point, and it's a long season. I'd prefer it to be J.D. Closser as the backup, but what do I know, right?
- Hill is going to pitch in relief today. I imagine this will change if Marquis is having a complete-game no hitter or something, but other than that the idea is to get a few innings out of Hill and hopefully see an improvement in his ability to pitch in the zone.
- Gordon Wittenmeyer hints that last night's odd arrangement (putting Fukudome in
leftcenter and DeRosa in right) might become more common, as the Cubs try to work Mike Fontenot into the lineup so that we can have two lefties. (May I suggest Eric Patterson?) [Sorry about the mixup - I typed left and meant center for Fukudome. -CW] - Expect to see either Johnson or Cedeno or both today; both have hit Moyers very well in their careers. (Which is something I don't care about but Lou does.) Johnson was probably a given anyways. The other Cubs who have hit Moyers well are D-Lee and Rich Hill. (Maybe that's why he's starting today.)

Fun with regression to the mean

Let's go ahead and do a throwdown-to-showdown, between Cubs centerfield options Felix Pie and Reed Johnson. (It's a hot topic of discussion among Cubs fans who aren't too busy pining after Ronny Cedeno.) And let's use OBP as our stat of choice for comparing them for the moment. How much more often will Johnson get on base than Pie?
We're simply going to focus on 2008 production for just a minute, because people seem to be much more excited about 2008 production to date than they are about the latest build of the ZiPS projections, for instance.
According to Baseball-Reference.com, Reed Johnson has a .478 OBP in 23 plate appearances; Pie has a .217 OBP in 23 plate appearances. Obviously Johnson is a better choice as a center fielder, just based upon OBP, right?
At 23 plate appearances apiece, we know no such thing. What we do know, on the other hand, is that both of them are major league baseball players, and the central tendancy of OBP talent among major league players is roughly .330. That's the mean; now we can regress to the mean. (A great primer on how to do that is available from Sal at Athletics Nation.)
Once we go ahead and regress Reed Johnson's OBP to the mean, we end up with a .338 OBP. For Pie, once we regress to the mean, we end up with a .321 OBP.
Fun, right?

The Cubs have had a wild ride the past few days, somewhat masking the fact that the Cubs have a four-game winning streak under their belts. They haven't been winning pretty, but they've been winning.
And while Lou calls it simply "playing his bench," I don't know how many teams are sitting two starters on back-to-back days in this early in the season. Ryan Theriot and Felix Pie have been sitting in favor of Ronny Cedeno and Reed Johnson. Both Cedeno and Johnson have been taking advantage of their opportunities; Johnson is hitting .375/.474/.438 so far, for an OPS of 912, while Cedeno hits .333/.400/.444, for an OPS of .844.
Meanwhile, Pie has a .200/.238/.200 line to his name, and Theriot is at an amazing .207/.281/.241 batting line on the season so far.
I don't think either Pie or Theriot have precisely lost their jobs yet - Pie is probably in a platoon situation for the time being, with Johnson eyeing more of Pie's playing time. His game-winning hit probably helped his cause some.
Theriot, on the other hand, needs to seriously keep his eyes open for some infield predation at this point. Pie was a top prospect who was held out of a lot of trading talks by the Cubs this winter; Theriot's no better than a lot of minor league journeymen at this point and is lucky to have a spot on a 25-man roster.
[Yes, there may be some wishful thinking in that paragraph. When June rolls around and Pie is either traded or at AAA, while Theriot is still our starting shortstop, I plan on eating my own arm off for fun.]
