Nick Ahmed
Turning our attention to the Diamondbacks, Nick Ahmed is a bit of a Braves throwback. The slick fielding and speedy infielder was the Braves' second round pick in the 2011 draft and was in the Braves' farm system until he was sent to Arizona in the Justin Upton deal. Ahmed stayed with the Diamondbacks since the trade and struggled to stay healthy and produce at the plate, although he did win back-to-back Gold Gloves in 2018 and 2019. While he did make over 200 plate appearances for the Diamondbacks this season, he was released by Arizona at the beginning of September to make way for Jordan Lawlar's promotion. At least he would still be in line for a ring if Arizona wins it all.
Jace Peterson
Another Braves throwback, Jace Peterson came to the Braves via the other Justin Upton trade with the Padres this time. Jace would go on to be a familiar face during the Braves' rebuild as he slashed .240/.326/.342 in 356 games with the Braves from 2015-2017. Somewhat surprisingly, Jace has gone on to long career as a bit of a journeyman in the league and he landed with the Diamondbacks at the trade deadline in 2023 to less than great results with them.
Mark Melancon
Finally, another former Braves closer makes the list in Mark Melancon. Melancon came to the Braves in 2019 at the trade deadline as his career was beginning to wind down. However, he performed admirably in those 1.5 seasons including a 2.78 ERA in 23 appearances during the COVID-shortened 2020 season. Melancon would play for the Padres in 2021 before signing a two year deal with Arizona before the 2022 season. Sadly for Mark, he missed all of the 2023 season on the IL while dealing with shoulder issues and won't get the chance to play in the World Series this year.
