Roy Halladay may have been a Phillie for just four seasons, but his impact on the Phillies, the fan base, and the city was felt well beyond those four years.

Halladay died Tuesday in a plane crash in the Gulf of Mexico. He was 40.

Halladay's death shook the sports world. His former teammates went to social media to remember Halladay. Phillies managing partner John Middleton and chairman David Montgomery shared their memories of Halladay. Cole Hamels, a member of the Four Aces with Halladay in 2011, said Halladay taught him so much more about life than just baseball.

As NBC Sports Philadelphia's Jim Salisbury wrote, Halladay was all business on the mound, but the side that stood out the most about Halladay was just how much he cared for other people.

In 2010, his first season with the Phillies, Halladay won the NL Cy Young and then was the runner-up in 2011. He pitched a perfect game in Miami in 2010 and then tossed one of just two playoff no-hitters in baseball history.

Halladay, in a short time, became one of the most beloved figures in Phillies history, and Tuesday night and Wednesday morning, fans showed their appreciation by leaving a Phils hat with "thanks for the memories" written in sharpie on it, a signed Halladay photo, a Halladay shirt, roses, candles lined up to form Halladay's No. 34 and more in a memorial to Halladay at Citizens Bank Park.


Here are some photos as of Wednesday morning:
