Rockies Look to Bounce Back Against Marlins with Lorenzen on the Mound

After a frustrating 2-1 loss on Opening Day, the Colorado Rockies are eager to level the series against the Miami Marlins. One silver lining from yesterday’s game was the debut of first baseman TJ Rumfield. Making a notable entrance into Major League Baseball, Rumfield stands out as the sole rookie on the Opening Day roster. He became the tenth Rockie to make his MLB debut on Opening Day, and the fifth to start the game, joining the ranks of Trevor Story, who last accomplished this feat in 2016. Rumfield’s performance included a broken-bat single in the ninth inning, marking him as the 60th Rockie to record a hit in their first MLB game, the last being Kyle Karros on August 8, 2025.

Today, all eyes will be on Michael Lorenzen as he takes the mound for his Rockies debut, having signed a one-year, $8 million contract in the offseason. Lorenzen has expressed his enthusiasm about joining the Rockies and addressing the challenges of pitching at altitude. His spring training performance saw him struggle through four starts, posting an 0-1 record with a 10.97 ERA. However, he also showcased his talent while pitching for Team Italy in the World Baseball Classic, where he had a standout outing against Team USA, contributing to Italy’s surprising 8-6 victory.

Lorenzen’s history against the Marlins adds a layer of intrigue to the matchup. He has faced Miami 17 times, including six starts, and holds a solid 4-2 record with a 2.33 ERA against them. At loanDepot Park, his record stands at 2-2 with a 2.76 ERA, suggesting he has found success in Florida’s ballpark.

On the opposing side, Lorenzen will contend with Marlins’ right-hander Eury Pérez. Signed out of the Dominican Republic in 2019, Pérez made his MLB debut in 2023 but faced setbacks, missing all of 2024 due to elbow inflammation that required Tommy John surgery. Returning to action in June 2025, he made 20 appearances for Miami, finishing with a 7-6 record and a 4.25 ERA over 95.1 innings. Pérez has faced the Rockies twice, both games played at Coors Field, where he has a 1-1 record and a 2.89 ERA.

First pitch is scheduled for 2:10 PM MDT. Fans can catch the action live on Rockies.tv, or tune in on KOA 850 AM/94.1 FM, with Spanish coverage available on KNRV 1150.
