Michael Choice lined a double into the left-field corner that scored one run, though Leonys Martin was cut down at the plate on a relay throw from left fielder Carlos Quentin to shortstop Everth Cabrera to catcher Yasmani Grandal.
The play was close enough that Washington decided to challenge the call.
"I asked Martin if he was safe, and he said yes, so I asked for a review," Washington said. "[Third-base coach Gary Pettis] said he got in there too, but Martin was adamant."
The umpires then conferred behind home plate for between two and three minutes while an official took a look at the play in the truck. The call was then overturned, the Rangers were awarded another run and the inning resumed -- even after all the players had left the field.
Choice was given two RBIs on the double and the inning continued, though Padres reliever Alex Torres struck out J.P. Arencibia to end the frame to preserve a 10-5 lead.
