You could also go with Babe Ruth and Tris Speaker (1915).
Or, you know, Pujols and Trout.

I am biased, but I had the pleasure of seeing Paul Molitor and Robin Yount play side by side many times at County Stadium between 1978 and 1989, with Molly starting at second base, and then moving to third, and the Kid playing at shortstop.

As teammates (from 1978 to 1992), the numbers they put up are pretty staggering:

Games played: 4,016
At Bats: 15,929
Runs: 2,605
Hits: 4,736
Doubles: 868
Triples: 195
Home Runs: 386
RBI: 1,964
Stolen Bases: 623
Total Bases: 7,152
AVG: .297
OBP: .359
SLG: .449
OPS: .808

The only teammates I know of to have more combined hits than Yount and Molitor's 4,736 are Roberto Clemente and Bill Mazeroski, who tallied 4,895 hits between 1956 and 1972. Of course, they played in 4,472 games combined to 4,016 for Yount and Molitor.

Best power hitting duo of all-time? The two duos that immediately come to mind are Ruth and Gehrig, and Aaron and Mathews.

Ruth and Gehrig were teammates from 1923 to 1934.
Aaron and Mathews from 1954 to 1966.

Ruth and Gehrig combined to hit 859 home runs, driving in 3,029 runs.
Aaron and Mathews combined to hit 863 home runs, driving in 2,627 runs.

That's a lot of balls flying out of the park!

Right behind them, Willie Mays and Willie McCovey hit 813 home runs as teammates, driving in 2,344 runs.
