San Francisco also removed righty Dan Slania from the 40-man via outright assignment. He cleared waivers. Another 40-man casualty, infielder Engelb Vielma, did not. Joining the Giants’ MLB roster are catcher Aramis Garcia and a trio of pitchers: righties Tyler Herb and Tyler Beede along with lefty D.J. Snelten.
Johnson has already bounced around between a few organizations this winter, moving from Atlanta to Cincinnati and then out west. The Giants will gladly stash him in Triple-A if he ultimately clears waivers.
As for Calixte, the 25-year-old has touched the majors briefly but hasn’t hit much at all in limited opportunities. At Triple-A in 2017, he posted a .243/.283/.421 slash over 401 plate appearances.
