Demp has a worse ERA and has given up more homers in your stats, but he had a better K:BB ratio before today and his K/9 is 7.3 vs 4.7 for Lowe. Demp's WHIP is also better in those stats. As for everything going for him last year, Dempster had a better WHIP on the road last year and a better K/9 away from home. He was very good at home and on the road last season. I don't think the K/9 is a valid argument when comparing these two. Lowe works toward contact on the ground. He never has been a big K pitcher. Again, I'm glad the Cubs avoided Lowe, but I don't see that Dempster has been better than him. 147 K is his career high. And when you pitch to contact, you rely more on defense and luck to to keep good numbers. Because Dempster has a higher K rate, he's more likely to be better the rest of this season. I'm not crazy about the contract either, but given their similar numbers this year, Dempster's better numbers last year, Dempster being cheaper and Dempster being younger, Dempster was the better signing.
