But manager Bob Melvin cautioned reporters not to read too much into the early session.
"We haven't done very well offensively, there's no secret to that," Melvin said. "But we've had a lot of guys out for early batting practice this year. I wouldn't say this was anything odd. We're working to do the best we can."
The A's also rank last in the American League in runs scored (84) and have scored seven runs or fewer in every game this year and 44 consecutive games dating back to Sept. 10 of last season -- the longest such streak in Oakland history.
Yet, they are in second place in the American League West.
"Based on the fact we haven't swung the bats great, our record's not horrible for that," Melvin said. "We're still doing some decent things other than hitting.
"We're third in the league in pitching, and we're last in hitting. That kind of speaks for itself."
