Jefferson Rojas has been the biggest positive surprise out of camp by a healthy margin. But Pedro has been #2 and he's got a healthy lead on #3.
The power this spring looks like it's grown into being probably average-ish, but that's way better than what I was expecting coming into the spring. This is a guy with plus defense, plus plate discipline, and plus contact ability. Those pluses with 5-10 dong power is a quality bench guy or second division starter. With 15+ homer power? Now we're talking about a quality starter. Need to make sure he can keep the groundballs in check, and that the new power doesn't have a major contact tradeoff (it hasn't this spring), but it's exciting.
