MLB concludes Ankiel investigation

NASHVILLE, Tenn. -- Major League Baseball announced two suspensions on Thursday related to the investigation of shipments of human growth hormone to players, but Cardinals outfielder Rick Ankiel will not be disciplined.

Outfielders Jose Guillen, newly of the Kansas City Royals, and Jay Gibbons of the Baltimore Orioles have been suspended 15 games each for violations of the league's substance abuse policy.

Major League Baseball began enforcing penalties for the use of anabolic steroids at the start of the 2004 season. In 2005, HGH was added to the list of banned substances.

Ankiel has been reported to have received shipments of HGH from Signature Pharmacy in 2004. He met with MLB officials in September after the reports emerged, originally in the New York Daily News.

Two investigations remain open, with discipline still possible for Rangers outfielder Jerry Hairston Jr. and Indians pitcher Paul Byrd. According to the MLB release, the remaining investigations "should be completed shortly."
