Manager Terry Francona told reporters Tuesday that an MRI revealed the swelling.
"Everything is OK," said Francona, after the Indians' 6-5 Cactus League loss to the Giants. "He's got a little swelling in there, but nothing structurally is (wrong) or anything like that.
"There's a pretty good chance we're going to bump him back a start. We're just trying to work through some stuff. His wife (Karelis) is expecting in about a week to 10 days. We're trying to figure out between bumping him back and him leaving to be with his wife -- we're still working our way through that."
Carrasco allowed eight runs on eight hits in the second inning Monday against the White Sox. Afterward he told reporters that he threw 90 percent fastballs because he wanted to work on that pitch. He said he kept waving catcher Yan Gomes off when he called for another pitch.
Now, with word of the swelling in Carrasco's elbow, perhaps he didn't want to throw his breaking balls because they hurt his elbow.
"Structurally the elbow is the same as it was, which is really good news," said Francona. "You look inside any pitcher's shoulder or arm, that's some of the worry sometime when you do that, but structurally he's really good."
Carrasco suffered a broken right hand on Sept. 17 when he was hit by an Ian Kinsler line drive. He missed the run to Game 7 of the World Series, but was thought to be an important part of the rotation this year.
Last season Carrasco went 11-8 with a 3.32 ERA in 25 starts despite his broken hand and a strained left hamstring that put him on the disabled list at the end of April.
