BP's Goldstein wrote about this, so I looked it up. Kyle is on fire in the hot Tucson sun. If we were to bring him up, who do we push down? Do we need three catchers, 12 pitchers?
Since he has already been up, not sure of the concerns about "rushing" him. He is 24, turns 25 in Sep. Given he can also play some OF, he could get some OF and 1B playing time. A little extra pop would go a long way in this line up.
