A federal judge ordered the reporters jailed after they refused to divulge their source. They have remained free pending an appeal to the 9th U.S. Circuit Court of Appeals, but Ellerman’s plea deal states that federal prosecutors will no longer try to put the reporters in prison. Ellerman agreed to plead guilty to four felony counts of obstruction of justice and disobeying court orders. He could spend up to two years in prison and pay a $250,000 fine. A judge still has to approve the terms of Ellerman’s plea agreement; no sentencing date has been set. Ellerman, who is licensed to practice law in California, also faces disbarment. Armour in Wrigley ivy: A sign of the times is finally sprouting at Wrigley Field: Advertising will appear among the ivy on the outfield walls. Doors in right field and left field will sport the logo for Under Armour, a sports apparel manufacturer. The outfield signs represent a change for the storied ballpark. “The Cubs are committed to finding alternative and creative revenue streams,” team marketing and sales director Jay Blunk said in a statement. Two San Francisco Chronicle reporters will avoid jail time under a plea agreement by a criminal defense lawyer who admitted leaking them secret grand jury documents from the BALCO steroids investigation. In court papers filed Wednesday in U.S. District Court, attorney Troy Ellerman said he allowed reporters Lance Williams and Mark Fainaru-Wada to view transcripts of the grand jury testimony of baseball stars Barry Bonds, Jason Giambi, Gary Sheffield and sprinter Tim Montgomery. Ellerman had represented Victor Conte, founder of the Bay Area Laboratory Co-operative, the Burlingame supplements lab that allegedly provided performance enhancing drugs to the elite athletes, as well as BALCO vice president James Valente. The Chronicle published stories in 2004 that reported Giambi and Montgomery admitted to the grand jury that they took steroids, while Bonds and Sheffield testified they didn’t knowingly take the drugs. The leaked testimony also was featured prominently in the writers’ book, “Game of Shadows,” which recounts Bonds’ alleged use of steroids. Under Armour also will have advertising rights for signs behind home plate. Young goes to Washington: Former All-Star Dmitri Young (Rio Mesa High of Camarillo) agreed to a minor-league contract with the Washington Nationals, getting another chance after the Detroit Tigers cut him last year following legal and substance problems. Young was released in September, and later that month he was sentenced by a court in Michigan to a year’s probation for assaulting his former girlfriend. Last summer, Young spent 30 days at a rehabilitation center for depression and alcohol abuse. Drew added to Red Sox roster: Boston officially added outfielder J.D. Drew to its roster after left-handed pitcher Lenny DiNardo was claimed on waivers by the Oakland Athletics. The club announced the $70 million deal with Drew on Jan. 26, seven weeks after preliminary agreement was reached. The deal had to be reviewed by Major League Baseball and the team needed an open slot on its 40-man roster for Drew, who played for the Dodgers last season. 160Want local news?Sign up for the Localist and stay informed Something went wrong.
