The national ESPN Radio feed may, however, be carried live on another station in those markets as well (for instance, WHB in Kansas City aired the ESPN feed of Kansas City Royals postseason games in 2014 and 2015, competing directly with the Royals Radio Network broadcast on KCSP).

However, they are not included in the subscription "Gameday Audio" package on MLB.com with the exception of the All-Star Game, for which no other radio play-by-play feed is available.

As of 2022, the primary ESPN Radio crew for Sunday Night Baseball consists of play-by-play announcer Jon Sciambi and color analyst Doug Glanville.

Marc Kestecher currently serves as the network's primary Baseball Tonight studio host, with Jim Basquil or Kevin Winter substituting for him if Kestecher was unavailable due to scheduling conflicts (mainly with his NBA on ESPN Radio play-by-play duties); he was preceded by Joe D'Ambrosio from 1998 to 2007.

This is mainly due to Sciambi’s unavailability as he is also the play-by-play announcer for Chicago Cubs games televised on the Marquee Sports Network.

Backup play-by-play announcers for MLB on ESPN Radio included John Schriffen, Karl Ravech, Mike Couzens, and Roxy Bernstein among others.

As of 2018, Dan Shulman called the World Series and one of the two League Championship Series with Singleton each year (Jessica Mendoza joined this crew in 2020, while Eduardo Pérez joined in 2021, in place of Singleton, who was co-hosting the pregame and postgame segments with Kevin Winter), while Sciambi calls the other LCS with Mendoza.

Various other announcers work the network's secondary regular-season, Wild Card Game and Division Series broadcasts as needed.
