Start time of O's Weaver tribute changed

BALTIMORE -- The Orioles announced Saturday that "A Celebration of Earl" tribute will now begin at 6 p.m. ET instead of 2 p.m. on Saturday, April 20.

The memorial, which will take place at Oriole Park at Camden Yards prior to the game against the Dodgers at 7:05 p.m., will honor the greatest manager in the organization's history, and the club's release said the time change is to allow more fans the chance to attend.

"A Celebration of Earl" will include a video tribute and a collection of notable guest speakers, including Jim Palmer, Brooks Robinson, Frank Robinson, current manager Buck Showalter, National Baseball Hall of Fame president Jeff Idelson and Earl's son, Mike Weaver.

One of six Orioles Legends to receive his own larger-than-life bronze sculpture at the ballpark last season, Weaver passed away in January at the age of 82. The Orioles are wearing a patch on their right uniform sleeve throughout the season in honor of the legendary manager. Fans are encouraged to visit www.orioles.com/4earl to share their memories of Weaver.

O's get positive reports on Wada, Johnson

BALTIMORE -- Steve Johnson and Tsuyoshi Wada threw in an extended spring game Saturday morning, and Orioles manager Buck Showalter said there were positive reports on both their performance and velocity.

Wada, who has been working with pitching rehab coordinator Chris Correnti, threw two innings, while Johnson pitched three.

The plan for Wada is to increase by an inning each time out as the lefty works his way back from Tommy John surgery. He could return as early as June.

"Today was a big day to get through," Showalter said. "I think the big day will be tomorrow, seeing how he feels afterward, facing hitters and pitching in a game."

Johnson (lat strain) could be nearing a rehab assignment. Outfielder Henry Urrutia, who has been slowed with a hamstring injury, is also close to joining Double-A Bowie.

Showalter said second baseman Brian Roberts (right hamstring strain) has not been cleared to start baseball activities and is just resting and doing rehab right now. Roberts isn't expected to be ready April 20, which is the first day he is eligible to come off the disabled list.
