"I didn't think of that," Washington said before Monday's game. "[Soto] did a good job [Sunday] and I thought I'd throw him a bone. No matter which one I catch, they both do a good job. Today I decided to go with Soto."
Soto was 2-for-3 on Sunday. Pierzynski said he has no issues with Darvish.
"Darvish and I are fine," Pierzynski said. "There's nothing there. That's it. Wash has been wanting me to take a couple of DH days and Geo had a couple of good at-bats [Sunday]."
With Pierzynski at DH, Lance Berkman was out of the lineup for the fifth straight game. He has not played since going a combined 0-for-6 last Monday and Tuesday against the Athletics.
"I understand it," Berkman said. "At this point in the season, you really can't afford to let a guy get his feet wet again when you're trying to win every game that's so crucial and you've had guys that have been in there playing pretty well. I understand it. The competitor in you obviously wants to be a part of things, but by the same token, I don't hold any grudges on anything that's gone on. It's just the circumstances of a playoff chase."
