"We feel like he's gone a little over half the season now and he has made a tremendous stride with the bat and his catching," said Orioles director of player development David Stockstill. "Teams are no longer pitching to him and because he's not being pitched to, we feel like it's better for his development to move him up to a level with people who are going to challenge him."
During his time in Frederick, the Orioles' top 2007 Draft pick was the team-leader in batting average (.342), hits (77), home runs (14), RBIs (38) and walks (43). In 225 at-bats, Wieters also boasted a team-high .560 slugging percentage.
Although the Orioles have been keeping Wieters on a conservative time line, unwilling to rush his development in the Minor Leagues, Wieters' promotion has been expected for some time. Earlier this month, Keys hitting coach J.J. Cannon said he didn't expect to see Wieters in a Keys uniform much past the June 23-25 All-Star break.
The promotion comes on the heels of Wieters' appearance in the Carolina League All-Star game earlier this week, June 24, in Myrtle Beach. Wieters went 1-for-2 in the game with an RBI single in the first inning. The Carolina League defeated the California League All-Stars, 3-1.
"It's a much tougher level," Stockstill said. "But I think he's capable of handling it, he'll be fine."
