Black has been called up and sent down twice this year after not performing. If he's the best we got in the minors then nobody else will make any impact. This is the Garrett Mitchell talking point all over again.
If that was Murphy's reasoning he should've remembered Myers threw an eight inning shutout earlier this season. Even Dillard said Murphy should've left Myers in the game.
In the off season I posted something a Padres fan posted on another site where he suggested one of their top prospects )don't remember who) for Frelick straight up and it was scoffed at by everybody here, including me.
