The Pirates are designating outfielder Marco Luciano and infielder Tsung-Che Cheng for assignment, as first reflected on the MLB.com transaction log. Pittsburgh needed to open two spots on the 40-man roster after this morning’s three-team trade that netted Brandon Lowe, Mason Montgomery and Jake Mangum.
Luciano, 24, was a waiver claim from the Giants a couple weeks ago. It was a no-risk flier on a former top prospect who has yet to show much at the big league level. Luciano once ranked among the sport’s top 15 minor league talents at Baseball America. He was then a teenage shortstop with massive raw power upside in a 6’1″ frame. His bat has stalled against higher level pitching and he has moved to left field after struggling with errors on the dirt.
San Francisco gave Luciano limited looks in 2023 and ’24. He hit .217/.286/.304 while striking out 45 times in 126 trips to the plate. The Giants kept him in Triple-A for the entire 2025 season. Luciano connected on 23 home runs while walking more than 15% of the time, but he struck out at a near-31% rate. He whiffed on more than 35% of his swings against Triple-A pitching. While Luciano hits the ball hard when he makes contact, the swing-and-miss and limited defensive profile have dropped his stock. He’s also out of minor league options, so he’ll need to stick on an MLB roster or continue bouncing around via DFA limbo.
Cheng is also a 24-year-old who had some prospect attention not too long ago. He was never as well regarded as Luciano was early in his career, yet he ranked among Pittsburgh’s top 10 prospects as recently as 2024. A lefty-hitting infielder, he appeared in his first three big league contests in April. He went 0-7 with three strikeouts and was caught stealing in his only attempt. He spent the rest of the season at Triple-A Indianapolis, where he managed a .207/.305/.267 line with one home run in 406 plate appearances.
The Taiwanese-born Cheng is a good athlete and a versatile defender, but he has been a below-average hitter since reaching the Double-A level in 2023. He has one option year remaining. Pittsburgh has five days to trade or waive both players.
