Pitching Definitions : A Hold
This pitching term was created by the people at USA Today and awards a relief pitcher who preserves the lead by not allowing any runs (earned or unearned) and passes it on to another pitcher for a save opportunity.http://baseball-almanac.com/stats2.shtml
That definition is not correct.
A Hold is credited any time a relief pitcher enters a game in a Save Situation (see definition below), records at least one out, and leaves the game never having relinquished the lead.
Note: a pitcher cannot finish the game and receive credit for a Hold, nor can he earn a hold and a save.
A Relief Pitcher is in a Save Situation when upon entering the game with his club leading, he has the opportunity to be the finishing pitcher (and is not the winning pitcher of record at the time), and meets any one of the three following conditions:
1. he has a lead of no more than three runs and has the opportunity to pitch for at least one inning, or
2. he enters the game, regardless of the count, with the potential tying run either on base, at bat, or on deck; or
3. he pitches three or more innings regardless of the lead and the official scorer credits him with a save.
