Just 42% of all the pitches he's thrown this year have actually landed inside the strike zone. That’s a problem for any pitcher, but Rojas especially, because hitters really haven't been squaring him up all that often. The problem is that major-league hitters are a completely different challenge. He doesn't need to suddenly become a command artist or start filling up the strike zone on every pitch. It starts with trusting your stuff and throwing more competitive pitches in the strike zone.
