• With no game Wednesday, righties Jarrod Parker and Grant Balfour got their work in at the club's Minor League complex. Parker, who has made one start this spring, said his focus was specifically on his two-seam fastball and on putting hitters away after getting ahead in counts. He felt satisfied with both. Balfour, who hasn't pitched in a game since offseason knee surgery, had no setbacks.
• The A's are determining whether right-hander Michael Ynoa needs another session throwing to live hitters before he sees his first game action of the spring. Ynoa missed the first 10 days of camp while fighting chicken pox.
• Manager Bob Melvin on making sure his club doesn't get complacent after winning the 2012 division title: "Teams will look at us differently this year, but we can't look at ourselves any differently. Once you start to pat yourselves on the back a little bit, that's a distraction that we don't need."
