Those are bad and confusing stats you're citing. It's not your fault, it's the way the stats read. But they should include holds. The 'save opportunities' were not necessarily real save opportunities.
For example, in that ugly 5-3 loss to the Yankees this year Brasier came in in the 7th and gave up the grand slam to Gardner. He was charged with a blown save.
But you know very well that he wasn't brought in to pitch the 7th, 8th and 9th. He was not going to get the save there no matter what. The best he was going to do was get a hold.
