Cincinnati Reds right-hander Jose Rijo plans to have a Magnetic Resonance Imaging test on his sore right elbow during a three-game series this week in Los Angeles.
Rijo said he will meet with Los Angeles Dodgers team doctor Frank Jobe to try to find the cause of the stiffness and pain that have troubled him since last season.
Rijo gave up five runs in six innings in a 7-3 loss Friday night at San Francisco, falling to 0-3 in three starts with a 4.30 ERA.
* RANGERS: Right fielder Ruben Sierra missed yesterday's game because of a sore left wrist.
Sierra injured his wrist Saturday in the fifth inning of a 5-3 loss to the Athletics. He was making a sliding catch when the grass caught his
glove and bent the wrist backward.
* PIRATES: The team probably will be without pitcher Bob Walk for the 14-day, 12-game trip that begins today in Montreal.
Walk left yesterday's game against the Phillies in the fourth inning with a strained right groin muscle and is expected to be on the disabled list.
* ASTROS: Third baseman Ken Caminiti suffered a mild separation of his right shoulder in a third-inning collision Saturday night.
Caminiti collided with the Padres' Tony Fernandez when Fernandez tried to steal third. Caminiti was replaced by rookie Juan Guerrero.
