The Royals tried to bring in free agent second baseman Neil Walker on a minor league deal with an invitation to big league camp, but he wasn’t receptive to that, Nick Cafardo of the Boston Globe reports.

As a member of the Royals, Walker could have pushed for a role at second (they already have Whit Merrifield and Adalberto Mondesi as possibilities there, however) or even the corner infield, where the team has lost first baseman Eric Hosmer (though it recently signed a replacement in Lucas Duda) and is likely to see free agent third baseman Mike Moustakas depart.

It’s not surprising that Walker’s holding out for a major league pact, though, considering the successful career he has enjoyed with the Pirates, Mets and Brewers. The switch-hitting 32-year-old is coming off his seventh straight season with at least 2.0 fWAR. Despite Walker’s quality resume, he’s one of many accomplished free agents still sitting on the open market as the regular season draws closer, as MLBTR’s Steve Adams pointed out earlier this week.
