Heyman recently brought up the fact that the Yankees lineup might have issues with balance now that Swisher and Martin are gone and A-Rod will miss most of the season. Here are the players on the Yankees who had 100 AB against lefties and had an OPS above .700.
Jeter, 214 AB, .941 OPS
Rodriguez, 146 AB, .924 OPS
Martin, 124 AB, .880 OPS
Teixeira, 175 AB, .865 OPS
Swisher, 185 AB, .769 OPS
Granderson, 216 AB, .762 OPS
Jones, 168 AB, .705 OPS
As you can see most of them are no longer on the team or will be injured most of the year.
