Anyone who has played fantasy baseball is familiar with the concept of trying to acquire players when they're slumping and trading players when they're on a hot streak. Let's take a look at the Cubs roster and see if we can spot any trends for the second half of the season. There are of course the traditional statistics such as ERA, wins and losses, WHIP, etc, but for the most part I'll be looking at some of the peripherals that are good indicators of what to truly expect from these guys. I'll begin with the starting rotation.
Carlos Zambrano - 8-3, 3.13 ERA, 5.76 K/9, 3.05 BB/9, 1.89 K:BB, 0.59 HR/9, .297 BABIP
There are three areas of concern with Big Z. The 5.68 ERA he put up in June, the alarming decline in his strikeout rate and of course, the shoulder strain that put him on the disabled list. Yeah, he'll be back by Friday, but anytime a pitcher goes down you have to worry about re-injuring himself. You can try and chalk up June to just having a bad month and maybe his shoulder was acting up on him before he actually told anyone, but what you really have to be worried about his is the 5.76 K/9 rate he's sporting this year.
It seems to have been a conscious decision on his part to go less for the strikeout and gain some more control on his pitches. His walk rate has dramatically improved to go along with the decrease in his strikeout rate (3.05 BB/9 this year compared to 4.20 and 4.84 the last two seasons). And you can't argue with the success he's had for the most part this year, but there's not a lot of pitchers that can put up ERA's in the low three's with that low a strikeout rate...I mean, we're talking almost Jason Marquis territory here. His groundball to flyball ratio has improved as well with his new approach and I think he can still dial it up whenever he needs to, but I' d sure feel a lot more comfortable if he got that K/9 rate above six at least.
