Oakland had whiffed 1,322 times entering the day. Only the 2007 Rays had done so more times in a regular season in the AL. The Major League record is 1,529, set by the D-backs in 2010.
Both the Rays and D-backs finished at the bottom of their division in those respective years, but the A's offense has helped the club into postseason contention.
"We have some guys that strike out a bit, but knock wood, we're working around some deficiencies," manager Bob Melvin said. "I think we've been pretty good about that all year. We'll have certain guys struggling in the lineup and others picking them up."
Josh Reddick entered the day with a team-leading 146 strikeouts, which is tied for eighth-most in the AL with the Rangers' Josh Hamilton.
