In a story that is just breaking, San Francisco Giants outfielder Melky Cabrera has been suspended by Major League Baseball for 50 games after testing positive for elevated testosterone levels. With only 45 games remaining in the regular season, the suspension ends Cabrera's season with the Giants.

In a statement, Cabrera said: “My positive test was the result of my use of a substance I should not have used. I accept my suspension under the Joint Drug Program and I will try to move on with my life. I am deeply sorry for my mistake and I apologize to my teammates, to the San Francisco Giants organization and to the fans for letting them down.”

The Giants released the following statement: “We were extremely disappointed to learn of the suspension of Melky Cabrera for violating Major League Baseball’s Joint Drug Prevention & Treatment Program. We fully support Major League Baseball’s policy and its efforts to eliminate performance enhancing drugs from our game. Per the protocol outline by Major League Baseball’s collective bargaining agreement, the Giants will not comment further on this matter.”

Cabrera was the 2012 All-Star Game MVP and was arguably one of the most valuable players in the National League thus far this season. His .346 batting average is second to only Andrew McCutchen in the NL and he leads Major League Baseball with 159 hits on the season.

The loss of Cabrera will be a significant blow to a team that has lead MLB in runs scored in the month of August after the acquisition of Hunter Pence.

Entering Wednesday's game with Washington, the Giants are tied for first in the National League West with the Los Angeles Dodgers, and sit .5 games behind Pittsburgh for the Wild Card. Whether or not they can maintain their playoff push without Melky remains to be seen.

Unlike the Ryan Braun suspension from last season, Cabrera will not be appealing the ruling.
