LOS ANGELES -- The Rockies have slowed right-hander Eddie Butler's rehab from right rotator cuff inflammation, but righty Tyler Chatwood (right flexor tendon strain) and lefty Brett Anderson (broken left index finger) made strides in their respective rehabs on Wednesday.
Butler sought a second opinion at the behest of his agent, and after a consultation with Dodgers physician Neal ElAttrache, Butler will rest for a few days before resuming his throwing program. Butler threw 10 pitches off the slope of the mound on Monday.
"Everything looks good; he's feeling good; he's pain-free," head athletic trainer Keith Dugger said. "We're just going to probably back off another 4-5 days on his throwing, and pick it up maybe on the weekend playing catch again."
Chatwood and Anderson, who are on the same rehab schedule, each threw 47 pitches Wednesday, using all their pitches. Dugger said they'll throw another bullpen Saturday or Sunday, then after two days pitch live batting practice.
"It was fabulous for both of them," Dugger said.
Third baseman Nolan Arenado, out since suffering a broken left middle finger on May 23, will have X-rays taken on Thursday in Denver.
"I think it's going to be pretty close to healed," Dugger said. "If not, we'll get him out of the splint and start doing some movement and baseball activity. Or they might say keep him in [the splint] another week. But he's doing everything he can, and he's pain-free and is in that brace 24 hours a day."
Dugger also said left fielder Carlos Gonzalez (left index finger surgery) will have his stitches removed in about six days, at which point he will begin exercise and rehab.
