MIAMI -- As Rockies first baseman Daniel Murphy prepares to see a specialist about his injured left index finger, right-handed-hitting Mark Reynolds and left-handed-hitting Ryan McMahon are set to revise first base as part of their profiles.

Manager Bud Black said Murphy has an “avulsion fracture, mallet finger, there’s a lot of terms I’m hearing.” They’re sending Murphy to Scottsdale, Ariz., hand specialist Dr. Donald Sheridan to learn for sure, and there is no timetable on the absence. Black said after Sunday's 3-0 loss to the Marlins that right-handed hitting utility man Pat Valaika will be called up from Triple-A Albuquerque to replace Murphy, who will be placed on the 10-day injured list.

McMahon started Saturday night’s 7-3 loss to the Marlins, but moved back to second base for Sunday’s game. Reynolds started at the position where he was the main player for the Rockies in 2016 and '17, before signing with the Nationals last season.

In 2017, Black’s first year as manager, Reynolds, 35, batted .267 with 30 home runs and 97 RBIs as the Rockies qualified for the National League Wild Card Game. Reynolds signed a Minor League contract during the offseason, but there was little doubt he would make the team at a salary of $1 million.

“He played great first base defensively,” Black said. “Almost made the All-Star team. Now, this is a different year, two years later. … But our comfort level with Mark is such where we felt very strong about him making our team for a variety of reasons -- the talent level, his role, his position, his experience, what he did last year for the Nationals.”

Reynolds said, “You’re always ready and in baseball anything can happen. I didn’t expect this to happen to 'Murf.' But whatever they want me to do -- if they need me to go out there and play, I’m going to play. If they need me to pinch-hit, I’ll pinch-hit.”

McMahon put most of his effort into preparing for second base to replace DJ LeMahieu, who signed a two-year contract with the Yankees. But he said all along he would keep his corner -- first and third base -- skills fresh. The need arose quickly.

“Very comfortable,” Black said. “'Mac,' the last couple of years in the Minor Leagues, has been moved around, third base, second base, first base. [He is] an athletic player, solid at every position we put him.”

Valaika, a middle infielder by trade, played well at first base while playing several positions in Spring Training. Ian Desmond played primarily first base last season before the Rockies moved him to center field. Asked if Desmond was part of the first base picture, Black said he is “primarily in the outfield.” Black has said Desmond, originally a shortstop, is more comfortable at middle-of-the-diamond positions.
