I was wondering about some of the stats that you regularly see in baseball, and what criteria must be met to achieve such a stat, primarily with the relief and closing pitchers.
I understand that a starting pitcher must go at least 5 innings and leave with his team up at the end of the inning to be considered for the win, however after that I do not quite understand the stats for the pitchers to follow.
To my best knowledge I believe that if the game ever gets tied up again or the winning team drops below the other team's score once the starter is out, they will receive a no decision for their performance, and if the team comes back and retakes the lead, then the pitcher for that inning will be eligible for the win (not sure if there is an innings pitched requirement), while the loss will be awarded to the pitcher that last gives up the lead (regardless of the amount of innings pitched).
The stats that I am wondering about include, saves, holds, and innings pitched requirements for the win in the event that a game gets tied up after the starter leaves. As far as the saves and holds, what are the differences? Is there any requirement for a relief/closing pitcher to get the win once the starter is no longer eligible for it?
