Oakland managed to rebound from a 14-inning loss to the Yankeeson Saturday, when the A's blew a four-run lead in the 13th and lost on a two-out error, with a 5-4 win in the series finale at New York.
The A's then opened a big four-game series against Texas by building leads of 2-0 and 4-2. They wound up losing their third one-run game in four days.
"There have been a lot of one-run ballgames and things haven't gone our way," starter Dan Straily said.
Straily, one of 14 A's rookies, struck out eight and left with a 4-2 lead after 6 2-3 innings with Josh Hamilton due to bat and the bases empty.
