EDGE Analysis

Jansen has been slowed by both back and lat issues this spring, with Thursday's outing marking just his second of the exhibition season. Nevertheless, the veteran right-hander was sharp, as nine of his 13 pitches went for strikes. It is not yet clear whether Jansen will be ramped up in time for the regular season.
