I may write up more later on Perez plate discipline, but here is a list of players that are +/- 1% in K% and BB% to Perez's career line of 4.2% BB% and 9.3% K%. Try not to throw up.
Leaders from 2002 to 2012 (combined data):
| Name | PA | BB% | K% | wRC+ |
| Yuniesky Betancourt | 3869 | 3.3% | 9.4% | 78 |
| Bengie Molina | 3722 | 4.0% | 9.3% | 89 |
| Toby Hall | 1952 | 4.2% | 8.9% | 70 |
| Neifi Perez | 1769 | 3.8% | 8.1% | 59 |
| Kenji Johjima | 1722 | 3.8% | 8.6% | 90 |
| Mike Redmond | 1413 | 4.7% | 9.8% | 81 |
| Tike Redman | 1312 | 4.6% | 8.8% | 86 |
| Deivi Cruz | 1278 | 3.2% | 9.0% | 75 |
If you are still able to keep reading, I changed the query for just comparable single seasons:
Leaders from 2002 to 2012 (single season data):
| Name | Season | BB% | K% | wRC+ |
| Robinson Cano | 2009 | 4.5% | 9.3% | 120 |
| Freddy Sanchez | 2006 | 4.9% | 8.2% | 119 |
| Ichiro Suzuki | 2003 | 5.0% | 9.5% | 115 |
| Cristian Guzman | 2008 | 3.8% | 9.3% | 105 |
| Kenji Johjima | 2006 | 3.7% | 8.5% | 105 |
| Joe Crede | 2006 | 4.8% | 9.9% | 104 |
| Shea Hillenbrand | 2004 | 4.0% | 8.1% | 104 |
| Jose Lopez | 2008 | 3.9% | 9.8% | 101 |
| Ben Revere | 2012 | 5.0% | 8.5% | 98 |
| Kurt Suzuki | 2009 | 4.6% | 9.6% | 94 |
| Jay Payton | 2006 | 3.7% | 8.8% | 92 |
| A.J. Pierzynski | 2009 | 4.5% | 9.7% | 90 |
| Miguel Tejada | 2010 | 4.4% | 9.8% | 89 |
| Ichiro Suzuki | 2012 | 3.4% | 9.6% | 82 |
| Tike Redman | 2004 | 4.0% | 9.0% | 76 |
| Jack Wilson | 2005 | 4.9% | 9.1% | 71 |
| Yuniesky Betancourt | 2009 | 4.1% | 8.7% | 59 |
The list of player is full of some good, some bad and one walking scum of the earth. They are all high contact hitters and only Ichiro and Cano would be considered stars.
Perez hopefully will improve his plate discipline over his career as most hitters do as they age. If he does continue his current plate discipline levels though, he may end up struggling mightily at the plate.
