It's as good of an excuse as any: "Lou Piniella plans to experiment with the Cubs lineup, dropping leadoff man Alfonso Soriano to No. 2 in an attempt to keep him healthy while inserting Kosuke Fukudome fifth," reports MLB.com. Soriano continues to have difficulties with his quadriceps and the move is designed to have him making fewer steal attempts, apparently. Whether that is a valid reason or not, having his free-swinging ways move down in the order is a move in the right direction.

Unfortunately, this now apparently means that the Cubs' worst hitter in the everyday lineup -- Ryan Theriot -- is going to be leading off instead of hitting second.

So who should be in the leadoff spot? Mark DeRosa appears to be the best option, absent doing something radical like putting Derrek Lee there or moving Fukudome to center and placing Matt Murton in right field and the leadoff spot.

All of this is, of course, subject to change, and to change quickly.

And it may change with a trade. As much as the Cubs like Theriot, I believe they would prefer a better hitter in the leadoff spot. Moving Soriano down may make a trade for Brian Roberts or a center fielder even more likely.

Cubs f/x thinks Soriano and Fukudome should switch in Piniella's experimentation. Perhaps. But the idea that Fukudome is an ideal #2 hitter is based on his Japanese numbers. I would like to see a couple of month's worth of performance before handing him the keys to a table-setting position in the order.

Given the following information, who do you bat second in the lineup?

The Chicago Tribune's Phil Rogers says that the long-rumored trade for Brian Roberts "is almost certainly going to happen," perhaps yet this week. (Hat tip: Bleed Cubbie Blue.) The Cubs may have to give up Sean Marshall, Sean Gallagher, and Ronny Cedeno. That's a steep price for a good player, but who has only been an above-average league hitter in two of the five seasons he has played at least 100 games. Especially since it eliminates the top competition for Ryan Dempster in the fifth starter's slot.

In any event, Rogers goes on to speculate that the lineup would look like this: Roberts, Ryan Theriot, Alfonso Soriano, Aramis Ramirez, Kosuke Fukudome, Derrek Lee, Geovany Soto and Felix Pie.

He does not explain why it would be a good idea to put the Cubs' best hitter (Lee) in the sixth spot and their worst hitter (Theriot) in the second spot. The much more likely scenario would have Soriano and Roberts hitting in the 1-2 spots.

Side question: If that ends up being the lineup, when is the last time the Cubs had a lineup that fast.

Here's a consequence of Alfonso Soriano's injury: With Ryan Theriot moving to the leadoff spot, the Cubs don't have a number 2 hitter: "Piniella said he's considering batting catcher Jason Kendall second when he returns to the lineup during the Colorado series," reports the Sun-Times. "Jacque Jones hit in that spot Wednesday for the first time since April 10."

In Rob Neyer's Big Book of Baseball Lineups (Fireside, June 2003), author and ESPN.com columnist Rob Neyer named the following players to his first and second all-time Cubs' lineups:
