One National League All-Star right-hander is getting the biggest contract ever for a Pittsburgh Pirates pitcher, and another is expected to miss the start of the season for the New York Mets. Mitch Keller and the Pirates have agreed to a new $77 million, five-year contract, a person with knowledge of the agreement told The Associated Press on Thursday. The person spoke on condition of anonymity because the deal was pending a physical and not yet final.
