Ahh, the Brewers - everyone's sexy sleeper pick! Although Zambrano is more durable Sheets has been the better pitcher the last two years with WHIP of 0.98 and 1.07 compared to Z's 1.22 and 1.15. I'm not knocking Z - he's awesome but Sheets has been better IMO. Not sure why whip is the only stat you're including. A closer look at the stats shows that Sheets has better control. Thus, the better WHIP. But that's it in favor of Sheets. Let's look at their careers. Big Z: 1.27/.228/3.26 Sheets: 1.22/.258/3.83 That's career WHIP/BAA/ERA. Aside from the nearly idenitcal WHIP, Z has the advantage, and it's a fairly healthy one. Other pertinent stats: Big Z: 7.73 K/9 • 1.97 k/BB • .341 SLG • .656 OPS Sheets: 7.57K/9 • 3.79 k/BB • .417 SLG • .717 OPS Nothing surprising here. Z has the better numbers except for a lopsided advantage for Sheets in K/BB. But Z's OPS against is over .050 better, primarily because when people hit Sheets, they hit Sheets much harder. Factor in the age (24 vs. 27) and the durability, and it seems to me the Z is a prett clear cut winner. Sheets gets hit more often and harder than Z. He gives up more runs and Ks less people, too. Don't get me wrong, he's a great pitcher, but it seems like the only thing he's got on Z is control. I can't imagine anyone in their right mind would trade Zambrano straight up for Sheets. IMO Zambrano is going to keep getting better and unless he has some injury issues may very well wind up being the dominant SP in baseball over the next few seasons.
