WASHINGTON -- In February, when Padres third baseman Chase Headley strained his left calf during a drill, he showed up the next day with a limp and leaning on crutches.
On Friday, less than 24 hours after straining his right calf against the Nationals, Headley was walking around almost as though nothing happened.
And despite landing on the 15-day disabled list on Friday, Headley was encouraged that his injury won't keep him from the lineup for more than two or three weeks.
"It's definitely better than it was [the day after] in the spring," Headley said. "It feels quite a bit better than I anticipated it feeling today."
In February, Headley strained his gastrocnemius muscle, which is one of three muscles in the calf. He thinks that this latest injury is in the soleus muscle of the calf.
The Padres replaced Headley on the 25-man roster with infielder Jace Peterson, who was playing for Double-A San Antonio.
"When I was running toward the left-field line, I felt it tweak on me," Smith said. "I've had something similar before in Colorado where I think I missed three games."
Smith doesn't think he'll miss more than two or three games with the injury.
"I don't see it being much longer than that," he said.
