West Notes: Washington, Murphy, Castillo

The Athletics have hired former Rangers manager Ron Washington as a special instructor, as Susan Slusser of the San Francisco Chronicle and MLB.com’s Jane Lee (via Twitter) report. Washington, the club’s former infield coach, will not unseat current infield coach Mike Gallego. But he will work with the club’s big league players — particularly shortstop Marcus Semien, who paces the league with 15 errors thus far. Washington, of course, resigned from Texas late last year in rather dramatic fashion. He recently worked on the staff of the University of New Orleans.

Here’s more from out west:

• In other coaching news, the Padres have reportedly declined to allow Triple-A manager Pat Murphy to depart the organization to take a major league coaching job with the Brewers, and Ken Rosenthal of FOX Sports analyzes the decision. Though San Diego sources tell Rosenthal that the club simply wants to retain a valued employee while avoiding early-season turmoil at their top affiliate, others around the game tell him that the move is highly unusual because heading to Milwaukee would have constituted a promotion. That has led to some speculation that the Padres see Murphy as a potential coach at the MLB level — if not even a replacement option for current big league skipper Bud Black. “(Murphy) must have been made promises — big ones,” a rival executive tells Rosenthal.
• Mariners GM Jack Zduriencik and manager Lloyd McClendon each addressed the team’s acquisition of catcher Welington Castillo yesterday, as MLB.com’s Greg Johns reports. “It’s very challenging in this day and age to have catching depth,” said Zduriencik. “To add a catcher that has a reasonable amount of Major League experience is important to the entire organization.” McClendon, meanwhile, echoed the notion of adding depth and also emphasized that the team had no plans to insert him as the starter: “His playing time will be predicated by Zunino’s performance on the field,” McClendon said. “We’re not fooling anybody here. Mike Zunino is our everyday catcher.”
