Dunn was added to the lineup as the DH for Saturday's game against the Rangers, MLB.com's Jane Lee reports. Dunn was not in the original lineup for the A's, but the Rangers scratched lefty Derek Holland (head) and are now starting righty Scott Baker, so A's manager switched from a righty-heavy lineup to a lefty-heavy one. Dunn will hit second and replace Derek Norris, who was originally slated to be the DH.
