To be fair, Roberts did have 100 more plate appearances than Soriano in 2007, so Soriano's K totals would likely be up a bit, as would his HR totals. Also, I didn't explain that the runs per PA was lifetime, not just last year. Soriano's PA per run in 2007: 6.36 Roberts' PA per run in 2007: 6.95 Soriano's PA per run in 2006: 6.11 Robert's PA per run in 2006: 7.4 I included 2006 in the event someone wanted to argue that the Cubs heart of the order was clearly better than the Orioles heart of the order, even though I believe the two were very comparable. Clearly, the 2006 Nats heart of the order doesn't nearly compare to either of the 2007 Orioles or Cubs heart of the order. Just for giggles, I'll include the 3-5 hitters for each of the above teams: 2007 Cubs: 3rd: .309 .391 .496, 80 RBI 4th: .312 .381 .531, 122 RBI 5th: .256 .321 .401, 75 RBI 2007 Orioles: 3rd: .288 .353 .457, 109 RBI 4th: .276 .357 .422, 99 RBI 5th: .267 .325 .408, 85 RBI 2006 Nats: 3rd: .259 .346 .443, 93 RBI 4th: .269 .390 .467, 96 RBI 5th: .267 .339 .450, 99 RBI Looks like the 2007 Orioles win the RBI battle, followed by the 2006 Nats. But, the Cubs heart of the order had better AVG, OBP and SLG. 2006 Nats 1/2 OBP: .357/.362 2006 Nats 1/2 RS: 119/97 2007 Orioles 1/2 OBP: .375/.320 2007 Orioles RS: 107/97 2007 Cubs 1/2 OBP: .341/.336 2007 Cubs 1/2 RS: 127/99 Cubs get last place in OBP at the top of the order, but win the runs scored contest. Imagine how much better the Cubs heart of the order would be if Soriano hit lead off and Brian Roberts hit 2nd. Especially when you factor in how much better Fukudome will be hitting behind Ramirez. Without Roberts, Soriano/DeRosa would be much better than Soriano/Theriot and not too far off from what Soriano/Roberts would likely provide. One thing that does need to be considered about Roberts is the first year in a new league could hamper his numbers a bit. Some guys do quite well switching leagues. Others, well, not so much. It cannot be assumed that Roberts will automatically do better or equal performance switching leagues and facing a lot of pitchers for the first time. I will say that Soriano, Roberts, Lee, Ramirez, Fukudome is arguably one of the best 1-5's in baseball, depending on how Fukudome's numbers from Japan translate to MLB.
