After a series with the Astros, we're going back to PNC for a series against one of the few teams with a worse record than the Astros, the Padres. It's a good thing it's the Padres, too, because Yoslan Herrera is starting tonight and his WHIP is 3.84. That's not a typo. Herrera is actually allowing nearly 4 base runners an inning in his two starts with the Pirates. His problem has been well laid out just about everywhere; he's got good off-speed stuff that he's over-reliant upon, but he's over reliant upon it because his fastball is terrible. That's a catch-22 with absolutely no answer. Herrera is, quite simply, very bad and there's not anything that anyone can do to fix it.
