• Right-hander Chris Tillman, slowed this spring by abdominal soreness, threw 62 pitches over four innings Sunday in a Minor League game and received positive reports.

• The Blake High School baseball team in Montgomery County, Md., will have a No. 4 stitched into this year's hats to honor Orioles manager and Hall of Famer Earl Weaver, who passed away in January.
