Jered David Weaver (born October 4, 1982 in Northridge, California), is a Major League Baseball starting pitcher with the Los Angeles Angels of Anaheim.

Jered attended college at Long Beach State University where he was the 2004 College Baseball's Dick Howser Trophy winner as the national collegiate baseball player of the year. He also won college baseball's top pitching honor, the Roger Clemens Award. He was also named first-team All-American by Baseball America in 2004 as a starting pitcher. Weaver went 37-9 at Long Beach State and was 15-1, with a 1.62 ERA in his last season with 213 strikeouts and just 21 walks in 144 innings.

Younger brother of Seattle Mariners pitcher Jeff Weaver, Jered was drafted in the 1st round (12th pick overall) by the Angels in 2004. He and his agent, Scott Boras (who also represents the elder Weaver), held out until the end of May 2005 to sign which resulted in Jered getting a $4 million dollar signing bonus (which was actually much less than what they were originally looking for).

Jered was on the fast track to the Major Leagues just like his brother Jeff was, spending just over one month in single A before being promoted to AA. His minor league stats after less than one season include 7 wins, a 3.91 ERA, and 95 strikeouts over 76 innings.

He made his MLB debut on Saturday, May 27, 2006, starting against the Baltimore Orioles. He pitched seven shutout innings, striking out five, and earning the victory. This was followed with three more consecutive victories. Despite his success, when Bartolo Colón returned from the disabled list, Weaver was bumped out of the rotation and sent back down to the minors. He was recalled to the majors on June 30, 2006, when the Angels designated his brother, Jeff, for assignment.

After receiving nine wins without a loss at the start of his Major League career, tying the American League record set by Whitey Ford in 1950, Jered recorded his first loss on August 24, 2006 when he lost to the Boston Red Sox, despite allowing only one earned run in seven innings pitched, a home run to David Ortiz. He lost his second consecutive game to the Seattle Mariners on August 26, 2006, in which he gave up back-to-back home runs to begin the first inning and surrendered five earned runs in 4 2/3 innings.

He has an exceptionally straight fastball which he can control very well, as well as a changeup, slider and a curveball. He also throws sidearm occasionally for a strikeout or to fool hitters.
