SAN FRANCISCO -- Although Hanley Ramirez was placed on the 15-day disabled list Saturday, he said his strained left hamstring felt better than it did Friday night when he suffered the injury trying to go from first to third in the sixth inning.
"It feels better than last night, but it's still uncomfortable feeling in there," said Ramirez, who is likely out for a month with the injury.
Manager Don Mattingly was reluctant to offer a timetable, especially with memories of Matt Kemp's hamstring injury a year ago. Kemp rushed back and ultimately missed 51 games over two stints that wiped out one-third of his season even before he smashed into the fence at Coors Field and damaged his left shoulder.
"You never know how long it will be," said Mattingly. "You can't get to the game intensity of trying to explode when you need to. And he just got back and was swinging the bat and we're struggling to score runs. He's one of those guys we've been waiting for, looking forward to him back in the lineup. It's tough."
Ramirez said he was hoping the injury was a cramp, but soon realized the severity and did not argue with the club's decision to immediately put him on the disabled list only three starts after returning from thumb surgery.
"I'm with them. They know what they're doing," he said. "They want me to be 100 percent and not go out there for four games and have to go back out. I feel it's a good decision to get back 100 percent."
Ramirez said he first felt the hamstring when he reached the shortstop position. He continued toward third base, his stride shortening, and he felt the hamstring pull a couple of strides short of the bag, where he was tagged out after an awkward slide.
"I was so excited to get back on the field" after missing a month with thumb surgery, he said. "I'm going to work hard; nothing's going to stop me. This is going to make me stronger."
