The Orioles drafted Christian Walker and Zach Davies. The Diamondbacks are their fourth and fifth teams in the Majors per Baseball Reference.
Last season, Zach Davies’ strengths were his 34.5% hard hit percentage and his 87.4 MPH average exit velocity. They were the best of the Diamondback’s starters (minimum 2 starts, data from Baseball Savant). Also, his .315 On-Base-Percent (OBP) ranked as the fourth best starter. In general, his strengths were weak contact and keeping batters off the bases.
Perhaps to avoid rookie pitchers needing to pitch too many games, the Diamondbacks re-signed him.
