Matt D'Agostini wanted a fresh start. He will get at least that with the Penguins, who signed D'Agostini on Wednesday. D'Agostini, a right winger, agreed to a one-year contract that will count $550,000 against the salary cap if he plays in the NHL. The contract is a two-way deal. “Last year was tough, not playing a lot; so I look at Pittsburgh as a great opportunity,” said D'Agostini, who split the 2013 season with St. Louis and New Jersey. “I think I can bring some versatility and jump to the third or fourth line.” D'Agostini, 26, scored three goals and produced six points in 29 games last season. He is two seasons removed from scoring 21 goals with St. Louis. The Penguins, though up against the cap, are looking for bottom-six depth among forwards. The club is committed to 10 forwards on one-way contracts for next season. It is also committed to $64.2 million against the $64.3 million cap. Clubs can go over the cap by 10 percent in the summer and need not be cap compliant until season-opening rosters are set.
