Reggie Jackson is happy to praise David Ortiz, but he’s not ready to share his nickname.

Jackson appeared on HuffPost Live to promote his new book, “Becoming Mr. October,” and was asked by the host, “Some people say he might be the new Mr. October. He put up some big numbers.”

The host did not specify who exactly was awarding Ortiz with this nickname.

“He did a great job,” Jackson said of the Boston DH. “There’s only one Mr. October.”

Then Jackson muttered, possibly to himself, “We’ve got one day left. Don’t say nothing silly now.”

The host did not ask what Jackson had one day left to do, although the two did share an awkward laugh, before moving on to a different topic.
