SAN DIEGO (AP) — The Seattle Mariners have placed Felix Hernandez on the 15-day disabled list with a right calf strain, just the third time in his career the veteran right-hander has landed on the DL.

The Mariners announced the move Wednesday and recalled left-hander James Paxton from Triple-A Tacoma. Paxton joined the team in San Diego, where he was set to start Wednesday night.

Hernandez is 4-4 this season with a 2.86 ERA. The 30-year-old didn't travel with the team to San Diego and was examined by Dr. Ed Khalfayan in Seattle on Wednesday morning before the roster move was made.

There's been much attention placed on the decreased velocity of his fastball, but Hernandez has remained a highly effective pitcher, if not a bit inconsistent. Opponents are hitting just .217 against him.
