Rajai Davis, one of the A's key offseason acquistions, is headed to the 10-day disabled list due to a strained left hamstring.
The move is retroactive to April 22.
The A's also designated Rual Alcantara for assignment. The 24-year-old who was acquired in the 2011 Andrew bailey trade with Boston won the fifth starter job out of spring training, but posted a 16.71 ERA in three appearances this season.
To take their spots, the A's recalled right-handed pitcher Cesar Valdez and recently-acquired outfielder Ryan LaMarre.
Valdez,32, was recalled on April 20 to start against the Mariners. He allowed five hits and three earned runs in four innings. He was optioned to Triple-A Nashville the following day.
The 28-year-old LaMarre was acquired from the Angels on Sunday. In his only game with Triple-A Nashville on Monday, he went 1-for-5 with three strikeouts.
Former 49ers fullback Tom Rathman, who was not retained this season on Kyle Shanahan’s coaching staff, will be coming back to the organization in a permanent fashion.
Rathman, 54, who spent a total of 22 seasons as a player and coach, will be inducted into the 49ers Hall of Fame, CEO Jed York announced on Tuesday.
York wrote on Twitter:
“No one epitomizes being a @49ers more than Tom Rathman. So happy for him to take his place in the #49ersHoF
Rathman discussed having a role on the 49ers’ coaching staff after the hiring of Shanahan. But Shanahan had already promised the position of running backs coach to Bobby Turner.
“It was all positive,” said Rathman told NBC Sports Bay Area in February. “I have no hard feelings. It’s just the nature of the business. Everybody just has to understand that. In pro football, coaches get fired and new guys come in and they bring their guys. I totally understand it. I don’t have a problem with it. Being in the business for 28 years, playing and coaching, you understand what it is. You can never take anything for granted.”
Rathman played for the 49ers from 1986 to ’93. He was a starter on two Super Bowl-winning teams and seven NFC West champions. Used mostly as a lead-blocker for Roger Craig, Rathman’s best season came in 1989, when he caught 73 passes for 616 yards.
After his playing career concluded with the Los Angeles Rams in 1994, Rathman entered into a career in coaching. He coached under Steve Mariucci from 1997 to 2002. He returned to coach with the 49ers in 2009, serving on the coaching staffs of head coaches Mike Singletary, Jim Harbaugh, Jim Tomsula and Chip Kelly.
