Closer Reliability Report-2008 Season-Week 1

The first week was full of both saves and save opportunities. On the surface, most saves came from the teams' announced closers, but from the thirty teams, there were Save Opportunities (SO) from 50 different pitchers! Four announced closers (five if BJ Ryan is included) didn't even have a save opportunity.

Roughly that means that each team used one to two different pitchers in the first week alone to obtain a save. 1.67 to be exact, but 2/3 of a pitcher does not an effective fast ball make!

There were 75 SO in the first week and 51 of those were converted into saves. That is a conversion percentage of greater than two-thirds, or %68.00.

Announced closers were responsible for 47 of the SO and 43 of the saves. Other relief pitchers accounted for 28 other opportunities, but only 8 saves. So while non-closer relief pitchers had 37.33% of the SO, they only converted 28.57% of those (or 15.68% of the total saves). In contrast announced closers converted 91.49% of their SO.

So on the first week there were many opportunities for both closers and non-closers alike. However, the true closers had more opportunities and were more proficient at finishing their games. This make sense, closers' save opportunities generally come in the last inning of the game and they are of a more reliable stock then their relief teammates--hence the reason why they are indeed closers in the first place.

As the weeks go on, and more pitchers are used, more opportunities will come from multiple sources. From a fantasy sense, especially in deeper leagues, it may make more sense to bench RP that you just have on your roster for potential saves, and have more pitchers who can earn you other stats such as W, WHIP, ERA, etc.
