The offseason provides an opportunity for players to make more sweeping changes than during the regular season. It rarely makes sense to retool a swing or rebuild a delivery in the midst of the hustle and bustle of the 162-game season, but the winter does make that possible.
On Monday, Mets reliever Hansel Robles got a visit from Pedro Martinez at his home in the Dominican Republic. What did they do? They worked out, and Pedro helped Robles work on his delivery:
Robles has been an effective reliever for the Mets over the last three seasons despite a 10.4% career walk rate. Over his career, Pedro's walk rate sat at a low 6.7%. If his mechanical tips can push Robles in that direction, the Mets may find themselves with a lights-out reliever in 2018.
