This was heard on a conference call. This is a nice baseball metaphor mashup of “hit it out of the park” (to do something successful or an outstanding achievement) and “right off the bat” (immediately, without delay). Now if the person had hit it right off the bat and out of the park that would be an immediate outstanding achievement, right? Or just a home run? By the way, it seems like hitting it out of the park is a favorite idiom to mashup. A few past examples for your reading pleasure are “we really nailed it out of the park” https://malaphors.com/2015/08/18/we-really-nailed-it-out-of-the-park/ and “they blew it out of the park” https://malaphors.com/2012/10/27/they-blew-it-out-of-the-park/ A big thanks to Mike Kovacs for hearing this one and sending it in right off the park to malaphor central.
