BOSTON - Anyone watching David Ross hobble down to first base Friday night, barely able to put any weight on his right heel, knew they had witnessed the veteran catcher's final appearance on the field for a while.
And indeed, Ross was placed on the 15-day disabled list Saturday because of plantar fasciitis.
He was replaced on the roster by Dan Butler, who was promoted to the major leagues for the first time in his career.
"Everything points toward that [heel] tendon letting go [Friday] night,''said John Farrell of Ross, "which, in this case, is a positive. How many days it takes to recover, we'll see. But the 15 days should hopefully help this quiet down to the point of him returning.''
Butler has been in major league spring training the last few years and that will help his familiarity with the pitching staff. It gives the Red Sox two rookie catchers with Butler joining Christian Vazquez.
"He's always had a strong reputation for handling pitchers and his game-calling,'' said Farrell of Butler, "and in some ways, it's a real success story when you factor in that he was a non-drafted free agent, signed out of the Cape Cod League and was a backup catcher in college. With all of his work, it's paid off to realize a major league oportunity.''
"Dan's learning curve will be [centered] around getting to know the [opposition]. There's [already] that familiarity with the guys here.''
Butler, 27, has caught three of the Red Sox starters -- Allen Webster, Rubby De La Rosa and Brandon Workman -- in Pawtucket and has handled Clay Buchholz in some spring training games.
He was hitting .227 with four homers and 28 RBI in 76 games with Pawtucket.
Last year, he flashed better power with 14 homers and a .469 slugging percentage.
