I don't know Dane, if you break down the line up.
Altuve on top will give you .295 bottom, .315 high
Not much power 6 to 8 homeruns, 55-60 RBI, 80 + runs scored, 35 SB's.
A bona - fide table setter.
Valbuena is not going to hit much more than .240, but will hit 15 homers, if not a little more.
Three to six in the Astro order can and more than likely will hit 100 homeruns combined.
#3 - Gattis has hit 21 and 22 homeruns first two years, can improve on those numbers.
#4 - Carter - Chris Carter hit 37 homeruns last year, 29 in 2012, but, lots of holes in his bat, he's going up there swinging though.
#5 - Springer - Connecticut homey, seen him play as a kid, legit MLB power, hit 20 out last year, his rookie season
#6 - Rasmus - very sneaky pop, has hit over 60 homers the last 3 years combined, has hit over 20 homers 3 times in his 6 seasons.
#7 - Lowrie - will stabilize the order.
With the middle of the order you will not get average, you will get lots of power throughout.
