Good grief try to look even an inch beneath the surface. Your criticism is essentially boiling down to you thinking that every club in MLB is supposed to have 8 leverage relievers available to them at all times and anything less is inexcusable because it's easy to build a perfect bullpen in MLB as injuries and underperformance apparently don't exist in your view. Through a cascade brought about by a ton of rotation injuries, shorter starts from the rotation and heavy leverage group usage in the prior few games it was necessary to bump some mid leverage arms up the chain a bit. Nance didn't pitch that badly in the final game of the Angels series, and Fisher unfortunately had a little bi of a tough outing that was aided by an unfortunate well placed softly hit fly ball that fell in due to the alignment of the outfield. If/when the rotation rounds back into form and a lot of key starters begin to return the rotation innings should stabilize a bit, and with Garcia potentially nearing his return this can add another key leverage arm back into the mix.
