Phillies relief pitcher Ken Giles reiterated that he's "physically fine" and that there is "nothing wrong" with him, per MLB.com.
Giles struggled in his season debut Wednesday night against the Red Sox. He entered with a four-run lead, but was pulled with the bases loaded, two outs and a slim two-run advantage.
Giles' fastball sat in the 98-100 mph range in 2014. On Wednesday, he topped at 96 mph.
"He's just been down in his velocity," Phillies manager Ryne Sandberg said. "We'll just have to see. He said he feels fine."
Giles acknowledged that he'll make some changes to his approach moving forward.
"You know what? I've just got to make adjustments, and I didn't make adjustments tonight," Giles said. "So I've got to continue doing that."
