I immediately thought of this after his passing. McCarver obviously, had a really long career, broadcasting a total of 23 World Series (https://en.wikipedia.org/wiki/List_of_World_Series_broadcasters) and 20 All-Star Games (https://en.wikipedia.org/wiki/List_of_Major_League_Baseball_All-Star_Game_broadcasters) for three different networks (ABC (https://en.wikipedia.org/wiki/Major_League_Baseball_on_ABC), CBS (https://en.wikipedia.org/wiki/Major_League_Baseball_on_CBS), and Fox (https://en.wikipedia.org/wiki/MLB_on_Fox)) from 1985-2013.
For this discussion, I'm only going to focus on his national work. So I'm not going to include his local work like for the New York Mets.

Choosing Tim McCarver's "best" broadcast partner is subjective, but many longtime baseball fans and media critics would point to Joe Buck (Fox, 1996–2013). This partnership is widely considered McCarver's most memorable and successful due to its longevity and prominence.
Why Joe Buck is often cited as the best
Longevity: McCarver and Buck worked together for 18 seasons and called 16 World Series for Fox, more than any of McCarver's other pairings.
Success and prestige: The duo was the voice of MLB for a generation of fans and worked during a time of great national interest in the World Series, including events like the "Subway Series" and the dramatic 2001 World Series. Their work earned McCarver induction into the Sports Broadcasting Hall of Fame.
Strong chemistry: Despite their age difference, the two shared a strong on-air dynamic and were close friends off the air. Buck praised McCarver for helping him mature as a broadcaster and credited their partnership for his success.
Other notable partnerships
While his time with Joe Buck was his longest and most prolific, McCarver also had impactful collaborations with other broadcast partners:
Al Michaels (ABC, 1985–89): McCarver's partnership with play-by-play man Al Michaels also received high praise. Michaels himself called McCarver the "John Madden of baseball," recognizing his talent for explaining the game to a mass audience. Their broadcasts included the 1989 World Series, which was famously interrupted by the Loma Prieta earthquake.
Jack Buck (CBS, 1990–91): Teaming up with Joe Buck's father, legendary announcer Jack Buck, was also a highlight of McCarver's career. This pairing provided strong commentary on the MLB postseason for CBS.
