I did player search in MG, and there are 11 guys in the majors or AAA with zero power ... no career HRs for any of them. Here are the MiLB/MLB ABs for each
1,850 / 2,670
2,245 / 3,072
2,214 / 452
2,067
4,189 / 230
2,108
4,595 / 771
2,498
2,811
3,079 / 1910
2,191 / 5,140
soooo, 45,000 ABs with no HRs
