Major League Baseball officials have asked the Miami News Times for records the alternative newspaper obtained for a story on alleged use of banned substances by several players, including Alex Rodriguez.

Miami New Times editor Chuck Strouse said Tuesday the paper had not yet decided how to respond. Strouse described the MLB move as a request and noted that the league does not have legal subpoena power.

Investigators from MLB's Department of Investigations want to learn how the notebooks that the New Times reported belonged to Biogenesis anti-aging clinic founder Anthony Bosch were obtained, SI.com reported.

They also want to know the names of other players in the notebooks who were not named in the New Times report and, most importantly, want to see whether the publication will hand over the records.

The New York Daily News, citing two unnamed sources, reported that the MLB investigators had examined the notes and documents and were seeking to acquire them.

The Bosch notebooks and other logs describe PED regimens for Rodriguez, Melky Cabrera, Gio Gonzalez, Nelson Cruz and others from 2009 to 2012. Rodriguez has admitted doping from 2001 to 2003 but has vehemently denied these latest allegations.

According to SI.com, investigators will attempt to link the dates in the notebooks to independent evidence such as receipts for plane trips and overnight packages.
