• Left-hander Matt Harrison, who dealt with back issues early in camp, hasn't had any problems physically since he resumed his throwing program on Thursday.
• This spring, Washington has made a point to address his club's situational hitting -- specifically against the reigning NL West champion A's.
"I guess when you don't get it done, you have to say [the A's] got it done," Washington said. "That's the way it works. We had many opportunities, and we just didn't execute."
• Battling for a starting role this season, Michael Kirkman tossed two scoreless frames and struck out a pair in relief of Perez. He also allowed two hits, but managed to work out of a second-and-third jam in the bottom of the fourth.
"He could give us some depth," Washington said. "If he certainly gets to the point where he gets consistent, he has a good arm, and he's got good stuff. There's no doubt about that, and today was just an example of what he's capable of doing."
