Volquez told Julio Castro of the Dominican paper El Caribe:
"They were offering me a contract for four years, the same as Johnny Cueto, but I didn't feel it was right for me. I spoke with the lawyer and the general manager, and we all agreed on a single season," Volquez explained while in Boca Chica, Dominican Republic.
"Having a good year this season is my mission. Depending on my performance, we'll seek a contract of at least four years with the team," he predicted. "I can't define the amount we're going to seek following the next year, but it's going to be for that quantity of years." And should he have second thoughts, the 27-year-old pitcher (three years older than Cueto) indicated that some manner of offer is still on the table, saying, "Things remain open in case I want to sign during Spring Training or in the middle of the season."
