Baseball Reference Navigator от Dan Grochmal

Highlight and right click on a player name OR type "bbref {player_name}" in the Chrome search bar and you will be taken to that player's Baseball-Reference.com page.

Please note: If a player shares a name with another player that has played in the MLB, you might not end up where you expect.
For example "Ken Griffey" will send you to Ken Griffey Jr's page, and "Pedro Martinez" will send you to the page of the left-handed Pedro from the 90s with 114 strikeouts, not the three time Cy Young Award with 3,154 strikeouts.
