The Arizona Diamondbacks are set to face off against the Miami Marlins in a three-game series beginning today at loanDepot Park. In the opening game, Diamondbacks' right-hander Merrill Kelly, who holds a 2-1 record but a hefty 7.20 ERA, will be up against Marlins' Connor Gillispie, a relatively inexperienced pitcher with a 0-1 record and 3.86 ERA. Kelly's recent performance against the Orioles was solid but historically, he has struggled against Miami, registering a 6.56 ERA in four starts.

Gillispie, who joined the Marlins as a waiver claim, has shown promise in his limited innings pitched. Today's matchup will be pivotal for both teams, especially the Marlins, who have had a surprisingly decent start with eight wins in their first 15 games despite a roster overhaul. The Marlins' lineup includes Matt Mervis, who has quickly adapted to his new team with a .294 batting average and five home runs. Other key players, such as Griffin Conine and Kyle Stowers, have also started strong.
