Unlike the guys ahead of him on this list, Dan Uggla hurts his team in the field. He likely ranks as the worst defensive second baseman in the game. Fortunately, his bat has usually made up for this deficiency.
That being said, Uggla does not come without his troubles at the plate. He may be the safest bet in the game for 30 home runs, but the rest of his stats fluctuate rather wildly. His season-by-season batting averages look like this, starting in 2006: .282, .245, .260, .243, .287 and .233. That does not scream consistency.
Fortunately, Uggla walks often, so he still gets on base at an acceptable rate, even when his batting average disappoints. Also, as mentioned, there are few guys as reliable as Uggla in terms of power production.
While he plays a more one-dimensional game than the better second baseman, Uggla’s reliable and dominant power makes him one of the most valuable second basemen in the majors.
