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.

The MLB matchup on March 28 between the Miami Marlins and Pittsburgh Pirates will center around Connor Gillispie, who has earned a rotation spot due to injuries in the Marlins' pitching staff. Gillispie’s first Major League start comes under pressure, with injuries looming over other players like Edward Cabrera and Ryan Weathers.

Despite a strong spring training, Gillispie faced a tough challenge against the New York Mets, demonstrating vulnerability, particularly in strikeouts. With the Pirates’ lineup featuring players like Oneil Cruz and Andrew McCutchen, who are expected to bounce back after a disappointing opener, prospects for Gillispie's longevity in the game tonight seem limited. Betting on under 14.5 outs for Gillispie appears to be the strategic choice.
