"There's not really anything to make out of it," Robertson said. "My job is to get better every day and do what the manager asks me to do. It doesn't matter who is pitching, I'm just trying to get better."
The Rangers acquired Robertson on May 18 from the Padres at a time when they were desperately looking for healthy bodies. At the time, Robertson looked like a temporary replacement, but he has persevered through the summer -- even while playing with small fractures in his left cheek. Now he is starting to show up semi-regularly in the Rangers' lineup.
"There have been a lot of transactions, Triple-A, coming here," Robertson said. "Being a baseball player, you've got to be ready for anything and everything. It's all part of the grind."
