Former A’s All-Star Mark Mulder told The Chronicle via text Tuesday night that he will no longer be on the team’s telecasts in 2018. Mulder served as an occasional color analyst for CSN California, working 20 games in 2016 and 35 in 2017, and the A’s at one point had spoken to him about increasing his workload next season, he said. Mulder said Tuesday night he had “no clue” what had happened. “They told me a little over a month ago that they were going in a different direction,” he said. “The only thing I can really think of is that they are looking for someone who will maybe want the job full-time, not just part of the season like me.” Mulder, who was a baseball analyst for ESPN from 2011-205, was popular with fans and had earned positive reviews for his work with the A’s broadcasts.
