Marlins to promote Connor Norby

The Marlins are calling up infield/outfield prospect Connor Norby to make his team debut, as first reported by Isaac Azout of Fish On First. He’ll presumably receive regular playing time down the stretch.

Norby, 24, came to Miami alongside outfielder Kyle Stowers in the trade sending left-hander Trevor Rogers to Baltimore. While Stowers went right onto the big league roster (and has struggled considerably in his first 16 games), Norby was the more highly regarded young player of the two. 

Norby is a bat-first second-base/left-field prospect who’s hit well at every minor league stop, including this year in Triple-A, where he’s batting .293/.382/.496 with 17 homers, 24 doubles, a triple, 13 steals (in 16 tries) and a 12 percent walk rate. His 28 percent strikeout rate in Triple-A this season is admittedly a red flag, but Norby hasn’t had major strikeout concerns in the past.

It’s worth pointing out that Norby’s production has dropped off sharply since the trade, though he’s generally still holding his own outside of a dip in power, hitting .271/.338/.373 in 67 plate appearances with the Marlins’ affiliate in Jacksonville. Even still, Norby’s aggregate production in Triple-A between the two organizations has been 28 percent better than the league average, by a measure of wRC+, and the Marlins have little incentive not to see what they have in a player who could be a core piece moving forward.

Among the 30 big league teams, Miami ranks 27th in terms of production from its second basemen (again, per wRC+) — and that’s including the 144 plate appearances Luis Arraez received before being traded to San Diego (during which he batted .293/.343/.368). Otto Lopez has seen the bulk of the playing time at the keystone since that trade, but he’s batting just .236/.270/.316 on the season, making him one of the least impactful hitters in the entire league.

Lopez has provided huge value with his glove, but he can still impact that game defensively in a utility role while Miami gives a legitimate audition to Norby — a former top-100 prospect who’s looked largely MLB-ready for some time but fell down the Orioles’ depth chart due to the glut of touted young infielders present in Baltimore (e.g. Gunnar Henderson, Jordan Westburg, Jackson Holliday, Coby Mayo). 

There’s far less competition in this stripped-down version of the Marlins, which president of baseball operations Peter Bendix is rebuilding from the ground up. MLB.com currently ranks Norby third among Miami farmhands, while Baseball America pegs him sixth.

Norby’s pending promotion gives him nearly six weeks to make his case for a 2025 role. It’s not a true sink-or-swim test, of course. Norby only turned 24 in June and is in the first of three minor league option years. Even with a poor showing down the stretch, he’d still be in the mix to earn a spot on the roster next spring. He won’t lose his place in the team’s plans with a so-so team debut, but he can likely go out and cement himself in its 2025 plans with a productive run. 

Miami currently controls Norby through the 2030 season, and he’s not currently scheduled to be arbitration-eligible until the 2027-2028 offseason.
