Jacob Andrew Nottingham (born April 3, 1995) is an American professional baseball catcher and first baseman in the Seattle Mariners organization.

[2] He made his professional debut that year with the Gulf Coast Astros, where he spent the whole season, batting .247 with one home run and 20 RBIs in 44 games.

In 2014, he played for the Greeneville Astros, where he batted .230 with five home runs and 28 RBIs, and he started 2015 with the Quad Cities River Bandits.

In 119 total games between Quad City, Lancaster, and Stockton, Nottingham batted .316/.372/.505 with 17 home runs, 82 RBIs, and an .877 OPS.

After the season, the Brewers assigned Nottingham to the Salt River Rafters of the Arizona Fall League.

[8] Nottingham began the 2018 season with the Colorado Springs Sky Sox of the Triple-A Pacific Coast League.

[9] On the year, Nottingham only registered 6 at-bats, getting 2 hits including his first MLB home run off of Josh Tomlin of the Atlanta Braves.

[10] Nottingham appeared in a career-high 20 games in 2020, hitting .188/.278/.458 with career highs in home runs (4) and RBI (13) in 48 at-bats.

The Brewers, who were dealing with injuries to starter Omar Narváez and backup Manny Piña, immediately added Nottingham to the active roster.

[15] In his first at-bat back with Milwaukee, he hit a solo home run off of Los Angeles Dodgers starter Julio Urías.

[18] Nottingham being claimed off waivers twice by the Mariners within a span of a month exposed a loophole which was closed by the Collective Bargaining Agreement (CBA) that resolved the 2021–22 MLB lockout.

The new clause, in which a player can’t be claimed off waivers for a second time by the same ballclub within a season until each of the other teams have passed on him, is colloquially known as the Jacob Nottingham Rule.
