Brian Jeffery Horwitz, nicknamed "The Rabbi",[1][2] (born November 7, 1982) is an American former baseball outfielder who played for the San Francisco Giants in 2008, and won two minor league batting titles.

[3] As a freshman right fielder for the University of California at Berkeley Bears, where he majored in American history, in 2001 he batted .310, and had a team-best 11 stolen bases.

In 2003 as a junior, he hit .347 with a team-leading 47 RBIs (including a school record 8 on February 14, 2003)[4] and a .405 OBP and a .535 slugging percentage.

"[5] He had all the forms ready for chiropractic school, but he wanted the experience of playing pro ball for a half-summer, so he took the San Francisco Giants' offer of a uniform and $1,000 and signed as a non-drafted free agent in June of 2004.

[5] In 2006, he spent nearly half the season at San Jose of the California League, where he hit .324 with a .414 OBP.

Horwitz has a great two-strike approach, loves the opposite field, and doesn't strike out, despite a swing that can get a bit long and choppy.

[14]Horwitz started 2008 with Fresno, and was hitting .294 with a .351 OBP in 44 games when he was called up to the major leagues.

In 2009 with Fresno he batted .291 with 10 doubles, 4 home runs, and 26 RBIs in 76 games before his season was cut short with a left rib cage muscle strain.

In his minor league career through 2009, Horwitz had a .316 batting average, .387 OBP, and in 2,104 at-bats had 130 doubles, 279 RBIs, 223 walks, and 243 strikeouts.

"[16] "He's a right-handed-hitting corner outfielder, something we have a need for, obviously," John Mirabelli, the Indians' assistant general manager in charge of scouting said.

"[17] In 2010, Horwitz played in spring training with the Indians, and then in six games for Cleveland's AAA team before he was released on April 20.

[21] On May 30, 2008, the Giants purchased his contract from Triple-A when Dan Ortmeier went on the DL with a broken finger.

[22] Horwitz hit his first major league home run on June 2, 2008, off New York Mets starting pitcher Óliver Pérez.

[5] Horwitz became the first Jewish player to play with the Giants since the 1995–1996 tenure of pitcher Jose Bautista, and the eighth since they moved to San Francisco.
