Joseph Andrew Wieland (born January 21, 1990) is an American professional baseball pitcher for the Olmecas de Tabasco of the Mexican League.

He has previously played in Major League Baseball (MLB) for the San Diego Padres, Los Angeles Dodgers, and Seattle Mariners.

He has also played in Nippon Professional Baseball (NPB) for the Yokohama DeNA BayStars and in the KBO League the Kia Tigers.

He opened 2010 with the Crawdads, but an improved 3.34 ERA in 15 games earned him a promotion to the California League High-A Bakersfield Blaze in July.

In 2011, Wieland started the year with the Myrtle Beach Pelicans, the Rangers' new High-A affiliate, and then graduated to Double-A in late June.

On July 29, 2011, while pitching for the Frisco RoughRiders, Wieland threw a no-hitter against the San Antonio Missions, the Padres Double-A affiliate.

Wieland was called up to join the Padres' rotation when both Tim Stauffer and Dustin Moseley went on the disabled list early in the season.

[5] He made his Major League debut on April 14, 2012, against the Los Angeles Dodgers, allowing six runs in five innings to take the loss.

He began a throwing program at around mid-season but he suffered a number of setbacks due to soreness and a stress reaction and missed the entire season.

On December 18, 2014, he was traded to the Los Angeles Dodgers (along with Yasmani Grandal and Zach Eflin) in exchange for Matt Kemp, Tim Federowicz and cash.
