As things stand today, Christian Walker probably has a better chance of making the club out of camp than Kevin Cron. Then again, the incumbents always do, and it would not be surprising to see Cron leapfrog Walker on the depth chart.
After all, Walker himself was a surprise contributor at the major league level. He’d had some prospect status earlier in his career, but his star had faded considerably before last season when he hit .299/.354/.568 with 18 home runs in Triple A before getting a call-up to the bigs.
Of course, once there, he didn’t set the world ablaze: .163/.226/.388 across 37 games. He’ll be 28 by Opening Day, meaning there just isn’t the upside present in Lamb or Cron. Walker is classic Quad-A guy who might get some time if the Dbacks don’t think Cron is totally ready, or if they get hit hard by injuries, but there’s not much to hint at him being more than an organizational player.
Walker can play some outfield, which could get him the backup 1B job over Cron, but the Diamondbacks have very little reason to give Walker any time in the outfield barring injuries to David Peralta and Steven Souza, and even then, you’d like to see Socrates Brito playing everyday ahead of Walker.
