Jean Segura has been a very pleasant surprise for the D-backs, and certainly a much better player than he was over the past couple of seasons in Milwaukee. But is he a good lead-off hitter?
The typical leadoff hitter can usually run. He has a high on base percentage, good average and takes his walks. The leadoff hitter can handle the bat by bunting, good hit and run guy and doesn’t strike out a lot. He can create havoc on the bases when necessary. -- ProBaseballInsider.com
That seems a good general overview of the requirements.
