Ross is light-years more useful than Le Q, for sure, but even with the three bombs on his record, he's still hitting .242/.306/.478- which is no scarier than Russ Branyan territory. (Useful, but not clock-stopping.)
He's whiffed 55 times in 207 at-bats, which is also Branyan territory.
Denorfia's got to be better on defense and the basepaths. Ross is going to have to hit more than a fistful of homers to be more useful than Chris as a fourth outfielder.
