The Washington Nationals claimed shortstop Tsung-Che Cheng off waivers from the New York Mets and designated left-handed pitcher Konnor Pilkington for assignment on Wednesday. Nationals President of Baseball Operations Paul Toboni made the announcement.
Cheng, 24, spent five professional seasons in the Pittsburgh Pirates system after signing with them on July 2, 2019. He hit .251 with a .350 on-base percentage and a .385 slugging percentage and recorded 88 doubles, 21 triples, 35 home runs, 230 RBI, 112 stolen bases and 296 runs scored in 507 career Minor League games in the Pirates organization. He made his Major League debut in 2025, appearing in three games during the month of April. Cheng was claimed off waivers by the Tampa Bay Rays on Jan. 7 and by the New York Mets on Jan. 16.
A native of Pingtung County, Taiwan, Cheng was considered the “Best Defensive Infielder” and had the “Best Strike Zone Discipline” in Pittsburgh’s system entering the 2025 season, according to Baseball America. He hit .207 with 12 doubles, three triples, one homer, 36 RBI, 48 walks, 20 stolen bases and 36 runs scored in 110 games between Triple-A Indianapolis and Single-A Bradenton last season.
