Baseball superstar Barry Bonds has lost his collusion case against Major League Baseball.

Baseball arbitrator Frederic Horowitz has ruled in favor of MLB in the case in which Bonds claimed he couldn't get a playing job following the 2007 season due to a concerted effort by MLB to keep him out of the game, has learned.

Bonds' career ended at the time, when no job was forthcoming.

The ruling, made within the last few days, came in the form of an opinion written by Horowitz, who heard Bonds' case back in May.

Bonds, with the assistance of union lawyers, tried to make the case through circumstantial evidence that MLB's powers must have colluded against Bonds, as no free-agent players coming off an excellent year fails to get a job. The best evidence came in the form of Bonds' statistics, which were excellent in 2007: a .480 on-base percentage, a 1.045 OPS and 28 home runs in 126 games.

The basis of the case is believed to have gone something like this: How many folks with a 1.045 OPS can't get a job?

However, there was said to be no smoking gun in the case, and the arbitrator apparently didn't find the case compelling enough. While Bonds was still one of the better hitters in the game in 2007, perhaps the arbitrator believed there was leeway to wonder whether all 30 teams independently decided they didn't want an aging superstar such as Bonds, with serious baggage.
