Ramos will now go back to Washington this weekend to be re-examined by the team's doctor, Wiemi Douoguih. Ramos is expected to get an MRI. It marked the second time this season Ramos had to go on the disabled list because of the left hamstring strain. Ramos said the hamstring was sore on Thursday.
The young catcher is mystified as to why he is having hamstring problems this season. He thinks it's because of his right knee, which was surgically repaired last year, resulting in him putting "more pressure" on the left leg.
"I was working a lot on my hamstrings. I wanted to make it stronger," Ramos said. "I was feeling very good yesterday before the game. I don't know."
Solano, who is 1-for-6 in three games with Washington in 2013, was recently activated from the 7-day disabled list on Tuesday. He missed time because of a right ankle sprain, which he hurt trying to break up a double play at home plate.
Solano was able to play in a Minor League game on Wednesday for Triple-A Syracuse. He played all nine innings and said the ankle didn't give him any problems.
"I'm happy to come back," Solano said. "I want to help the team win. … I will have my chance to play."
