Runs Saved by Tigers Pitchers

Yesterday, I looked at Support Neutral Wins (SNW) and Winning Percentage (SNPCT) as ways to rank the all-time best Tigers pitchers. SNW says more about pitcher longevity while SNPCT is a measure of excellence. Another statistic which combines longevity with excellence is runs saved above average (RSAA). RSAA is the number of runs saved by a pitcher over an average pitcher's run allowed. It was created by Lee Sinnis and is similar to Pete Palmer's Pitching Runs which is calculated as follows:

(Lge Runs Allowed/9 IP - Runs Allowed/9 IP)*IP

How well this statistic balances longevity with excellence depends on which one you value more but it's considered by many analysts to be a reasonable measure for comparing pitchers across eras. The Top 20 Tigers pitchers of all-time in terms of RSAA are listed in the table below. Leading the pack are Tommy Bridges and Hal Newhouser, each with 301 runs saved above average.

The data for this analysis were extracted from the Lee Sinnis Complete Baseball Encyclopedia.

  1. It seems like Tommy Bridges is at or near the top of these lists. I've always felt he was the most deserving of a Hall of Fame spot (out of Tiger pitchers not already enshrined). What's your take?

  2. His only problem is he has fewer innings pitched than most Hall of Famers. I think he's borderline but he's definitely better than any other Tiger pitchers not in the Hall of Fame. He's a much better candidate than Morris.
