MLB chief: Science may be behind increased drug positives (Yahoo Sports)

There have been eight suspensions announced this year under the major league program for positive tests for performance-enhancing drugs, one more than in all of 2015, and reigning NL batting champion Dee Gordon of the Miami Marlins was among those penalized. ''The windows of detection on certain substances have been lengthened,'' baseball Commissioner Rob Manfred said Thursday after a quarterly owners meeting. ''There's one way to know: Did he test positive or did he not?'' Manfred said.
