Yahoo is messed. I just realized that for 7 inning games, if a RP comes in with a lead in the 5th (so a hold situation), and maintains the lead, Yahoo doesn't give them a hold.
Here is their response.
. In our game, a save situation will not be considered if the pitcher enter prior to the 6th inning of a game. Castillo entered the game in the 5th inning, so it was not considered a save situation and would not get a hold in his fantasy stats for this game.
