A Thousand Monkeys...

Since Sandy Alomar, Jr. became the Rockies starting catcher on July 31, the team ERA has dropped nearly a run per (5.02 pre-Alomar, 4.09 since), their WHIP (Walks Plus Hits Per Innings Pitched) has dropped 20 points (1.49 to 1.26), but their HR/IP has gone up slightly (.13 to .17). They are 10-6 since his acquisition.

The starting rotation in particular has been greatly affected by Alomar's presence:

Pitcher           Pre-Alomar  Since Alomar
                  W- L ERA      W-L  ERA
Mike Hampton      5-13 6.87     2-0  3.16
Denny Neagle      4- 7 5.92     2-0  0.45
Jason Jennings   10- 5 4.76     4-0  1.35
Denny Stark       6- 2 3.69     2-1  4.91
Shawn Chacon      5- 7 4.88     0-3 10.29

Talk about Jeckyl and Hyde numbers. It's just odd that some were hyde and became Jeckyl and some were Jeckyl and then became Hyde. It is worth noting that Alomar has missed two Chacon starts (including a 15-1 loss), 2 Hampton starts, and one Jennings start.

If he can calm this staff maybe he is worth keeping around.
