Walker has been total crap the last month plus. Neifi has been one of the best hitters on the team over that period. I'm a fan of Walker and would rather see him play - have been since he was at LSU. However, no manager worth his salt would be playing Walker over Perez given the way they've each performed lately. A good manager would take his best players and play them all the time, even during slumps, knowing that they would work their way through them and start producing again. A good manager would take his not as good players and keep them on the bench except for occassional spot starts during long stretches without a day off. A dumb manager like Dusty tries to put his players in and out of the lineup when they are hot and cold. It never works long term. What works is making sure your best players get the most AB's because over the course of the season that will mean you get the most production. Walker has 4 doubles in the last 5 or 6 weeks and nothing else besides a few walks and singles. His slugging percentage over that period is horrid. Six weeks hitting like that is beyond a slump, it's hurting the team. I hate seeing Perez get at bats, I'd rather see Theriot and Fontenot up and playing so they can become cheap, patient utility guys in the future. However, given what's on the major league roster, there's no good reason to play Walker over Perez until Walker shows something and Perez cools off. Walker doesn't have the glove to justify at bats when his OPS is around .600 for this long, no matter how much of a fan I am of him.
