Manny Ramirez almost ready to play for Athletics A minor wrist injury could delay Manny Ramirez's debut for the Oakland Athletics. Marcio Jose Sanchez / Associated Press / March 10, 2012 May 23, 2012, 6:18 p.m. Manny Ramirez might not be ready to play for the Oakland Athletics by May 30 when his suspension for a positive drug test ends. Manager Bob Melvin said the A's want to make sure Ramirez is fully prepared and comfortable with his swing before he plays in major league games following his stint with triple-A Sacramento. Ramirez was held out of Sunday's game with the River Cats because of a wrist injury that is deemed minor. Ramirez turns 40 on Wednesday, the day he could come back in Minnesota. The St. Louis Cardinals put utilityman Matt Carpenter on the 15-day disabled list because of a strained right side muscle. He was batting .288 with three home runs and 20 RBIs in 39 games, with most of his starts at first base in place of injured Lance Berkman. Carpenter is the fifth player the team has put on the DL this week. Rookie Matt Adams made his fourth start at first base Wednesday against San Diego. ... The Colorado Rockies put infielder Jonathan Herrera on the 15-day DL because of a strained right hamstring. Infielder D.J. LeMahieu was recalled from triple-A Colorado Springs.
