Timothy Donald Locastro (born July 14, 1992) is an American professional baseball outfielder who is a free agent.

His family were fans of the New York Yankees and of the Notre Dame Fighting Irish football team.

[21] On January 16, 2019, the Yankees traded Locastro to the Arizona Diamondbacks for minor league pitcher Ronald Roman and cash.

He also set the MLB record for most hit by pitches (22, or 8.8%) with fewer than 300 plate appearances, which in turn inflated his on base percentage (.357).

[41][42] On March 27, the Mets designated Darin Ruf for assignment, clearing the way for Locastro to make the major league Opening Day roster.

[43] He played in 11 games for the Mets, going hitless in 7 at-bats while appearing mainly as a pinch runner before he was placed on the injured list with back spasms on April 17.

[47] On August 12, he was activated and slotted in the lineup as the starting center fielder in that day's game against the Atlanta Braves.
