ATLANTA -- Braves slugger Evan Gattis has a total of two hits in 21 at-bats in June, so the threat of his impact on games probably outweighs his actual production.

But the mere threat is tangible, maybe because rival pitchers, catchers and managers have all seen what he can do to a baseball. Like when he crushed a neck-high Stephen Strasburg fastball beyond the bullpens back in April, or earlier this week, when he turned a pitch into a cloud of rosin -- literally -- in San Diego.
