PHOENIX (AP) — The Arizona Diamondbacks will wear a memorial patch on their uniforms for the remainder of the season to honor the 19 firefighters killed while battling a wildfire northwest of Phoenix.

In addition, jerseys with the name “Yarnell” and the No. 19 are hanging in the clubhouses of both teams for this week’s series between the Diamondbacks and Mets in New York.

The Arizona players will wear black arm bands for the Mets series. When the Diamondbacks return home, they will wear black jerseys for this weekend’s series against Colorado with the No. 19 on a white patch across the heart.

Beginning today, the Arizona Diamondbacks Foundation will give up to $100,000 to match fans’ donations to charities assisting the firefighters’ families and affected communities.
