Source-derived summary

David John LeMahieu (; born July 13, 1988) is an American former professional baseball infielder who currently serves as the manager for the Royal Oak Leprechauns of the Northwoods League. He played in Major League Baseball (MLB) for the Chicago Cubs, Colorado Rockies, and New York Yankees from 2011 to 2025.

The Cubs selected LeMahieu in the second round of the 2009 MLB draft out of LSU, and he made his MLB debut for the Cubs in 2011 before being traded to the Rockies before the 2012 season. With Colorado, LeMahieu won Gold Glove Awards in 2014, 2017, and 2018, was named an All-Star in 2015 and 2017, and won the National League batting title in 2016. As a free agent after the 2018 season, he signed a two-year contract with the Yankees, where he had played as a third baseman, second baseman, and occasionally as a first baseman.

His versatility on defense and hitting ability earned LeMahieu the nickname "LeMachine" from Yankees teammate Gary Sánchez. He was also called "Big Fundy" due to his fundamentally sound techniques. With the Yankees, he was named a starter on the 2019 All-Star team, and won his first career Silver Slugger Award that year. LeMahieu won the American League batting title in 2020, becoming the first player in the modern era to win a batting title in each league.

Early life and career

LeMahieu was born in Visalia, California.

Editorial analysis

Why this record matters

The phrase “american baseball player” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.

Evidence profile

Biographical claims are most persuasive when dates, appointments and relationships can be traced to records created close to the events described. The source revision retrieved here is dated Aug 31, 2026. The linked authority identifier is Q3011059. 1 of 1 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1988, 2011, 2025 and 2009.

Critical limits

A concise life account rarely captures disputed attribution, private networks or the changing language used to describe a career. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
