Adam Ottavino will be a big zero this season for the Yankees.

Or, to be more specific, he’ll wear it.

In making the reliever’s three-year contract official Thursday, the Yankees announced that the Brooklyn native will wear No. 0, the first player in franchise history to do so.

The righthander, who went 6-4 with a 2.43 ERA in 75 appearances with the Rockies last season and whose 112 strikeouts out of the bullpen ranked second in the National League and fourth in the majors, agreed to a three-year, $27-million deal last week.

Ottavino, who grew up a Yankees fan and still lives in New York, joins an already powerful bullpen that includes Aroldis Chapman, Dellin Betances, Zach Britton, Chad Green and Jonathan Holder. Britton, a trade-deadline acquisition last season, signed a three-year, $39-million deal, with a club option for a fourth year that could bump the total to $53 million, earlier this month.
