I think sometimes we're just so unaccustomed to any kind of Cub sustained excellence that we have to step back say "whoa".
There's a story at ESPN (Better Fastball Has Dempster Tossing Zeroes) that says in the last 100 years, Dempster is the 5th pitcher to not allow a run in 5 consecutive wins.
The others are Don Drysdale, Bob Gibson, Orel Hershiser and Brandon Webb.
Nice company, eh?
And it's nice that the bats have supported Dempster through this stretch of brilliance, yesterday scoring 4 runs on 9 hits which was more than enough to beat the Diamondbacks, who scored once.
Anyway, if you look ahead Dempster has potentially 2 more starts before the July 31st deadline, 3 if you count the 31st.
Of course I doubt he'll be a Cub much longer, but as long as he is I'm so looking forward to his encore performance(s).
