EDGE Analysis

Stephenson made his Grapefruit League debut Tuesday afternoon against the Phillies, but he issued two walks and gave up two hits in his one inning of work. The 30-year-old right-hander has been slowed all spring by lingering elbow soreness, and the Pirates apparently feel like he needs more recovery time.
