On the heels of four suspensions last week for performance-enhancing substance and recreational drug use, Major League Baseball this week handed out six additional reprimands. The 50-game suspension for one of those players, Rangers outfielder Cristian Santana, is detailed here.

Most prominent among the new batch is veteran minor league corner outfielder Jon Weber, who drew a 100-game suspension following his third positive test for a drug of abuse. The 32-year-old voluntarily retired on July 16, three days before his suspension was announced.

In the midst of one of his worst seasons, Weber batted .257/.326/.340 with only one home run in 241 at-bats in the Triple-A International League. He began the year with Scranton/Wilkes-Barre, but the Yankees released him on June 3 so that he could seek greener pastures. Weber landed with Toledo, but neither his performance nor fortune improved in the Tigers system.

Signed as a nondrafted free agent by the Reds out of Texas Tech in ’99, Weber batted .283/.358/.449 in 909 games in the affiliated minors. He spent two full seasons (plus parts of two others) playing independent ball, but he batted a solid .280/.353/.438 in Triple-A, where he spent much of the past six years.

The remaining four players, none of whom has ever played a game in the U.S., received 50-game suspensions. All played in the Rookie-level Dominican Summer League this season.

• Rays lefthander Francis Vizcaino tested positive for metabolites of Stanozolol, a performance-enhancing substance.

• Orioles righthander Saulo Alcantara tested positive for Formestane, a performance-enhancing substance.

• Dodgers righthander Wilmer Colmenarez tested positive for metabolites of Nandrolone, a performance-enhancing.

• Lefthander Guido Gomez, who pitched for the Cubs this season but is now listed as a free agent, tested positive for metabolites of Stanozolol, a performance-enhancing substance.
