A’s Select Carlos Duran

The A’s have selected the contract of righty Carlos Duran from Triple-A and optioned lefty Jacob Lopez, per a team announcement. Right-hander Jose Leclerc was transferred from the 15-day IL to the 60-day IL in order to open space for Duran, who’ll be making his MLB debut the first time he takes the mound.

Duran, 23, was just acquired from the Dodgers in exchange for outfielder Esteury Ruiz earlier in the month. He’s pitched 16 innings between the Triple-A clubs for the Dodgers and A’s in 2025 and posted unsightly results, due largely to poor command. Currently, Duran holds a 6.75 ERA on the season. He’s fanned a respectable 24.3% of his opponents but also issued walks at an untenable 16.2% clip (in addition to three hit batters and a pair of wild pitches).

This year’s command troubles notwithstanding, Duran has a decent minor league track record. He pitched 53 1/3 innings across three minor league levels with the Dodgers in 2024 and notched a combined 3.71 ERA with a robust 29.4% strikeout rate. His location still wasn’t sharp, evidenced by a 12.9% walk rate, but it wasn’t quite as rough as it’s been so far in 2025. Duran is averaging better than 95 mph on his heater this season and pairing it with a slider that sits about 10 mph slower on the radar gun.

That slider, in particular, has drawn heaps of praise from scouts. Baseball America in 2023 called it a plus-plus offering that stood as perhaps the best individual pitch in the Dodgers’ entire minor league system. That’s high praise, but commanding that slider (and his fastball) have been an issue for Duran — as one might expect from a pitcher listed at 6’7″. Duran also has a notable injury under his belt, having missed the 2023 season due to Tommy John surgery (which may also have contributed to his poor command dating back to last year).

Leclerc’s move to the 60-day injured list shouldn’t come as a surprise. The A’s placed him on the 15-day IL due to a lat strain last week. The team noted at the time that Leclerc would be shut down entirely for an indefinite period. There’s still no firm timetable, but it’s been clear for the past seven days that the right-hander wasn’t going to be a candidate to return from the IL at any point in the near future.

The A’s signed Leclerc to a one-year, $10MM contract in the offseason. He’s had an ugly start to his 2025 campaign, yielding six runs on 13 hits and five walks in only nine innings. Leclerc has whiffed just eight of his 46 opponents — a 17.4% rate that’s miles shy of his career 30.8% mark — and has seen his average fastball drop by more than one mile per hour. It currently sits at a career-low 94.2 mph.
