From Waiver Wire to Red Sox Gem: The Untold Story of Tsung-Che Cheng’s Rise in Boston

BOSTON—The Boston Red Sox’s most impactful offseason move may have been a waiver claim that barely registered on the transaction wire. Tsung-Che Cheng, a 24-year-old infielder from Taiwan, has transformed from an overlooked afterthought into a key contributor for a team fighting for a playoff berth.

Acquired in December 2025 after being designated for assignment by the Pittsburgh Pirates, Cheng was a depth piece. No one projected him as a lineup regular. But as the Sports Illustrated article “Red Sox’s Overlooked Offseason Waiver Claim Has Already Paid Off” notes, that perception has shifted dramatically.

Why did Boston take the chance? Scouting reports highlighted a compact swing, elite contact skills, and defensive versatility across the infield. His minor league slash line at Triple-A Indianapolis in 2025—.289/.354/.420 with 12 homers and 23 stolen bases—provided the “reason to believe,” as Yahoo Sports framed it. The front office saw a player who could handle shortstop, second base, and third base, filling a critical utility role.

The turning point came in spring training. Cheng forced his way onto the Opening Day roster. On April 7, 2026, he recorded his first MLB RBI single against the Toronto Blue Jays, a sharp line drive to left field. The ESPN clip (available at espn.com/video/clip/_/id/49310496) shows a calm, disciplined at-bat. That hit sparked a stretch of consistent production.

Since May 1, Cheng has slashed .307/.372/.480. He’s played 45 games, primarily at shortstop and second base. Defensive metrics from FanGraphs rate him as above-average at both positions. His 0.8 WAR already exceeds what Boston expected from the waiver wire.

Behind the scenes, Cheng’s adaptation has been methodical. He works with a translator but conducts postgame interviews in English. Teammates describe a relentless work ethic. He arrives at the ballpark four hours before first pitch, studying video of opposing pitchers. Coach Alex Cora said: “He never looks overwhelmed. That’s rare for a rookie.”

The cultural adjustment was significant. Cheng moved from Taiwan to the U.S. at age 18. The language barrier tested his patience. He credits veteran infielder Trevor Story for mentorship. “He showed me how to prepare,” Cheng told reporters. “The game is the same everywhere. The approach must be different.”

What does this mean for Boston’s future? The waiver claim validates a low-risk, high-reward strategy. The Red Sox have historically been aggressive on the waiver wire. Cheng’s emergence could influence how the front office evaluates similar players. His ceiling remains unclear, but the floor is a capable everyday infielder.

Cheng’s rise is not a fluke. It is the result of scouting diligence, player development, and personal resilience. From waiver wire to Red Sox gem, the story is still being written.
