IMO, that's better. If it were me saying the same thing I'd go with something like* "the huge wave of prospects we've had that have become productive MLB starters right away gives us a convenient baseline to compare others to. Contreras looks like a starter in that light, but even with his improvement Almora still needs to improve/a platoon partner." *I write that out not to be condescending, but to take you at your word, and also because I spend all day writing and tone policing emails so it's an occupational hobby
