The San Francisco Giants didn’t win the Bryce Harper sweepstakes, but it wasn’t for a lack of trying.

Harper, who agreed to a deal with the Phillies for a baseball-record 13-year, $330 million contract on Thursday, also had a competitive offer from the Giants.

San Francisco offered Harper a 12-year contract that would have paid him $310 million, according to NBC Sports Bay Area. This was the second consecutive year the Giants lost out on a big-name star, the website said, failing to land then Marlins OF Giancarlo Stanton who was traded to the Yankees instead.

Harper’s agent Scott Boras, in a phone call to The Post’s Joel Sherman, said his client had a wide variety of deals on the table.

“We had average values of $45 million offered on shorter-term deals,” Boras said. “We had a full buffet.’’
