Dinelson Lamet Hernandez (born July 18, 1992) is a Dominican professional baseball pitcher for the San Diego Padres of Major League Baseball (MLB). He made his MLB debut in 2017.
An international free agent, Lamet agreed to a contract with the Philadelphia Phillies in 2012, but a problem with his documentation prevented the deal from being completed.
The San Diego Padres signed Lamet in June 2014 for a $100,000 signing bonus. He made his professional debut with the Dominican Summer Padres of the Dominican Summer League, and pitched to a 2.99 earned run average (ERA) for the Fort Wayne TinCaps of the Class A Midwest League in 2015. In 2016, Lamet began the season with the Lake Elsinore Storm of the Class A-Advanced California League.
In 2019, Lamet played for Lake Elsinore and El Paso before being activated from the injured list on July 4. In 14 starts, Lamet recorded an ERA of 4.07 with a record of 3-5. He struck out 105 batters in 73 innings.
After spending the beginning of the 2021 season recovering from a UCL sprain, Lamet made his season debut as the starting pitcher against the Milwaukee Brewers on April 21, 2021.
However, he was removed from the start after two innings and 29 pitches after experiencing right forearm tightness. Lamet pitched in 22 games in the 2021 season, only nine of which were starts. He recorded a 4.40 ERA and 57 strikeouts in 47 innings.
