All-Star Information on Player Pages
To see if a player was on an All-Star roster in a given season, you can look in the Awards column on tables on their player page. An "AS" link indicates they were an All-Star that season, and clicking on the link will take you to the All-Star Game for that year. Here's an example from Henry Aaron's page:
Additionally, the Appearances on Leaderboards, Awards, and Honors section on player pages lists each year that the player was an All-Star. An asterisk means they were on the roster but did not play, and a position in parenthesis means they started the game at that position.
The number of times the player was an All-Star is listed at the very top of their player page.
To see a player's stats in All-Star Games, first navigate to their
Advanced Stats page from the navigation bar:
Then scroll down to the All-Star Batting or All-Star Pitching table.
Years with Multiple All-Star Games
Note that for some seasons, two All-Star Games were held. There were multiple East-West All-Star Games in 1939, 1942 and from 1946 to 1948. The NL and AL held two All-Star Games in each year from 1959 to 1962, which allowed Henry Aaron to be nominated to the All-Star team more times (25) than he had seasons played (23) in his career!
All-Star Indexes for Teams
On franchise history pages, a list of every player who represented the team at the All-Star Game can be found in the Honors section of the toolbar.
Those pages list every All-Star for that franchise in each season, as well as their stats in each of those games. Here are those batting and pitching registers for the Atlanta Braves, for example:
