Connor Robertson

The D-Backs received Robertson as a part of the Dan Haren trade last year and then traded him this offseason to the Mets. Beyond eating up innings in relief for Triple-A Tucson, the Diamondbacks didn't get much mileage from him. Having spent the majority of the last two seasons at that level, Robertson has struck out a batter per inning during that span. His command has been inconsistent overall, but showed signs of improving in last season. Robertson's ability to miss bats should at least earn him a look during spring training for a middle relief spot. More likely, though, he will find himself at Triple-A for the Mets.
