SAN FRANCISCO -- The tumor removed from the left index finger of Rockies left fielder Carlos Gonzalez on Tuesday was diagnosed as a post-traumatic neuroma, or nerve-related tumor, which is benign. The end of the Rockies' tweet says all laymen need to know: "Aka: good news."
The pathology report on Gonzalez, whose return won't truly be known until after his stitches are removed in a little less than two weeks, was part of a positive day of health news for the Rockies.
Right-handed pitcher Tyler Chatwood (right flexor tendon strain) and lefty Brett Anderson (broken left index finger) each threw a bullpen session Friday, their first since they were placed on the disabled list. In each case, it was 25 pitches, all fastballs, and it went well.
Also, righty Eddie Butler, who made his Major League debut in a loss to the Dodgers last Friday and went on the 15-day disabled list with right shoulder inflammation immediately thereafter, has responded well to strengthening exercises. Butler said he hopes to throw long-toss at 90 feet on Saturday, if cleared to do so.
Third baseman Nolan Arenado, out since May 23 with a broken left middle finger, had an intense running workout Friday. The Rockies will re-evaluate the finger when they return from the current road trip Thursday. If all goes well, he's a candidate for a Minor League rehab assignment.
