For the first time this weekend, players will wear colorful, non-traditional uniforms featuring alternate designs as part of the inaugural Players Weekend. The players will also have the opportunity to have a nickname placed on the back of the jerseys made by Majestic Athletic, as well as to wear and use uniquely colored and designed spikes, batting gloves, wristbands, compression sleeves, catcher's masks and bats. Some players chose to stick with their last name on their jersey.
Here's a breakdown of how the Astros are celebrating Players Weekend:
Manager A.J. Hinch
Tribute patch: Nine-- Hinch is paying tribute to former Stanford baseball coach Mark Marquess, who is retiring after 41 years. He wore No. 9.

Jake Marisnick: "Big Fudge"
When he was on the disabled list while playing for the Marlins a few years ago, Marisnick was admittedly eating too much junk food and his teammates -- including his close friend, Christian Yelich -- took notice, giving him the nickname "Big Fudge," which is also the nickname of a character named Marshall on the sitcom "How I Met Your Mother."
Tribute patch: Mom and Dad -- After his junior year in high school, Marisnick had a sit-down talk with his parents and told them he wanted to play baseball for a living and not play football. They supported him fully.

Gurriel has been such a huge part of the Astros' success this year, he's blossomed into a popular player with the fans. Feel free to call him "El Yuli."

This doesn't require much explanation. Gattis is certainly as strong as a bull.
Tribute patch: Mom and Dad -- His parents, Joe and Melynda, divorced when he was young, but they supported him through some dark times earlier in his life.
Carlos Beltran: "Ivan"
Ivan is Beltran's middle name, and those who are close to him in his hometown in Puerto Rico call him Ivan, instead of Carlos.

Josh Reddick: "Red Dawg"
Reddick wanted "Spiderman" on the back of his jersey, but instead chose the nickname he had as a child.

James Hoyt: "Hoyter"
Hoyter is simply a take on Hoyt's last name.
Tribute patch: Tony Phillips -- Phillips, the late former big leaguer, played with Hoyt in independent ball when he was 52 years old. He worked out with Hoyt and helped arrange him to get looks from pro teams.
Ken Giles: "100 Miles Giles"

Tribute patch: Estele and Brody -- Estele is Giles' wife, who gave birth to their first child, Brody, a year ago.

Tribute patch: Family
Francis Martes: "Chanchi"

Dallas Keuchel: "Kid Keuchy"
"Kid Keuchy" is Keuchel's long-time nickname, as well as his Twitter handle.
Tyler Clippard: "Clip"
If you're a baseball player with a two-syllable name, it's not uncommon for it to get shortened to one. Thus, "Clip."
Tribute patch: Mom and Dad -- Clippard's parents, Bob and Debbie Clippard, always put Tyler on good youth teams so he could compete with the best. Among his teammates on a Senior League team in 2001? Future Rockies stars Troy Tulowitzki and Carlos Gonzalez.
