MIAMI -- Pirates reliever Arquimedes Caminero is known for his blazing fastball, a pitch that often clocks in faster than 100 mph. But he has quietly, and quite successfully, diversified his arsenal recently.
Caminero has essentially improved upon his signature pitch, a four-seam fastball, by making frequent use of a sinker. He began throwing the pitch on Aug. 1, according to PITCHf/x data, and it's been his go-to offering ever since.
"I've been mixing it up. Just trying to turn my fastball into another pitch," said Caminero, who also utilizes a cutter, slider and split-fingered fastball.
