After a tough loss on Tuesday night, the Jays came back for the series win. Swee-ee-t. Last night's game had the feel of a loss in the making early on. Falling behind 2-0 with Harden looking sharp on the mound is not a recipe for success, but the boys used patience and the big hit from Vernon along with fine bullpen work to head for Texas with a second straight W notched in their belts.
It was quite a series, as the Jays faced the three young pitching stars of the A's- Haren, Blanton and Harden. Jason Kendall was acquired this off-season; many, myself included, thought that part of the reason for the acquisition was to provide a steadying influence on the young pitchers. I reminded myself of the positive effect Pudge Rodriguez had on young pitching staffs in Florida and Detroit the past two seasons. I wondered if one could test whether this supposed steadying influence could be observed statistically.
So, I did a study. I looked at the effect of arrival since 1980 on veteran catchers on the young pitchers on their new teams. I used only teams which had at least 2 pitchers, who were either 25 or younger or had less than 30 prior starts as of the arrival of the veteran catcher. Each of the pitchers had to pitch in the previous season. It is for this reason that Javy Lopez was not included in this study, as Daniel Cabrera and Erik Bedard did not pitch in the major leagues prior to Lopez' arrival. The seasons included in the study were: Ivan Rodriguez, 2003 and 2004, Gary Carter 1985 and Carlton Fisk, 1981. It should be noted that 1981 was the strike season; that is the reason for the reduction in innings pitched for each of the White Sox starters that season.
Here are the results of the study:

I had anticipated that there would be some improvement in the ERA, as all of these catchers were fine defensive players. I guessed that there would be small improvements in the walk and home run allowed rate. The results were not exactly what I expected- the ERA improvement of over half a run per game is larger than I would have guessed, and the improvements in strikeout and hit rate surprised me. I stress that the study is only a first look at this question. There are on average improvements for young pitchers, and those would need to be accounted for. If one wanted to, one could do a cohort study with young catchers.
Gregg Zaun will probably have a number of young pitchers on the staff in 2006. We'll see how well he does.
