The biggest and brightest stars in Major League Baseball will gather Tuesday night for the 2016 MLB All-Star Game at Petco Park in San Diego.

Let's take a look at the starters and pitchers for the American League and National League and how their careers played out in the college baseball world.

American League

OF: Jackie Bradley Jr., Red Sox South Carolina, 2010 CWS MOP

Before he was taking the outfield at Fenway Park for the Red Sox, Jackie Bradley Jr. commanded the outfield in Columbia. Bradley Jr. led South Carolina to back-to-back national championships in 2010 and 2011. The outfielder earned Most Outstanding Player honors at the 2010 College World Series following a 10-for-29 performance at the plate.

Bradley Jr. is just the second Gamecock to be named an All-Star since Brian Roberts played in the 2005 and 2008 All-Star Game. Bradley Jr. will bat ninth and play left field for the American League.

LHP: Chris Sale, White Sox- Florida Gulf Coast

Chris Sale received only one Division I scholarship offer from Florida Gulf Coast and played three seasons with the Eagles. The southpaw had a 2.52 ERA in 52 appearances and posted 20-4 record, including a perfect 11-0 in his final season. Sale and the Eagles captured three Atlantic Sun regular-season championships.

Sale became the first FGCU student-athlete to have his No. 21 retired in 2015. The White Sox pitcher will be the starting pitcher for the American League on Tuesday.

RHP: Brad Brach, Orioles, Monmouth

Monmouth Athletics
Brad Brach's relief efforts for the Baltimore Orioles this year resulted in the pitcher becoming the first former Monmouth player to receive a MLB All-Star nod. Brach left quite the mark on the Hawks program as the right-hander still holds the school record with 29 wins and 277 strikeouts. He posted a 2.44 career ERA and on April 13, 2007 he tossed the school's first no-hitter since 1990.

Brach heads back to San Diego, the organization that drafted the righty out of Monmouth in the 2008 MLB Draft.

RHP: Will Harris, Astros, LSU

LSU has become one of the most consistent college baseball programs in the past 20 years and Will Harris contributed much success during his four-year career in Baton Rouge. Harris led the Tigers to back-to-back College World Series appearances in 2003 and 2004 and played across the board for LSU. Harris started as a first baseman and third baseman before moving to the mound. At the plate, Harris knocked out 19 home runs, including one in the super regionals that sent the Tigers to the 2004 CWS. The Astros reliever becomes the 10th former LSU player named to the All-Star Game.

LHP: Andrew Miller, Yankees, UNC

Earning his first All-Star recognition, Andrew Miller dominated for North Carolina in three seasons before he was selected as the sixth overall pick in 2006. Miller set several records during his time in Chapel Hill, including the single-season record (133) and career record (325) for strikeouts. The left-hander is also third with 27 career wins and fourth with 309 innings pitched. The Tar Heels retired Miller's No. 33 this past season.

Miller earned the Roger Clemens Award in 2006 for the nation's top collegiate pitcher, which is fitting now that former Tar Heel is a reliever for the Yankees.

RHP: Steven Wright, Red Sox, Hawaii

For the first time in Hawaii program history, Steven Wright will represent the Rainbow Warriors for the American League on Tuesday. The right-hander appeared on the mound for three seasons in Hawaii and posted an 18-6 record in 24 starts. As a junior, Wright earned second team All-American honors for his pitching efforts.

Known across the league for his rare knuckleball, Wright was drafted in the 2006 MLB Draft by the Cleveland Indians, who traded him to the Red Sox in 2012.

AL reserves: C Stephen Vogt, Azua Pacific; C Matt Wieters, Georgia Tech; 3B, Josh Donaldson, Auburn

National League

2B: Ben Zobrist, Cubs, Dallas Baptist

Ben Zobrist may have played only one season in a Dallas Baptist uniform, but the second baseman made an impression on the program. Zobrist transfered from junior college and played an instrumental role in the program's first season as a NCAA Division I program. As a senior, Zobrist led the team with a .378 batting average during DBU's 44-16 record season.

The infielder became the second DBU player to win the World Series after Kansas City's win in 2015. However, he is the first Patriot to ever start in a MLB All-Star game and will leadoff for the NL on Tuesday night.

3B: Kris Bryant, Cubs, San Diego Toreros

The Cubs young phenom played in the San Diego Toreros program for three years and during his junior season, the infielder crushed a NCAA-best 31 home runs, the most by any player since the switch to composite bats in 2011. In addition to his home runs, Bryant posted a .329 batting average with 75 hits and 62 RBIs in 2013. Bryant swept the awards for nation's best player by winning the Golden Spikes Award and Dick Howser Trophy. The Cubs selected Bryant with No. 2 overall pick, making him the highest draft pick in Toreros history.

Bryant will be third in the batting order for the National League.

C: Buster Posey, Giants, Florida State

FSU Athletics

The lone non-Cub in the starting infield, Buster Posey made a splash in Tallahassee long before he suited up behind the Giants' home plate. Originally the Seminoles' shortstop, Posey made the transition to catcher and became the first sophomore catcher to be named a Johnny Bench Award finalist. Posey would win the award his junior year in 2008 and he also received the Dick Howser Trophy and Golden Spikes Award.

Posey will bat in the fifth spot on Tuesday night.

RHP: Jake Arrieta, Cubs, TCU

Despite a few rough starts the past month, it's tough to go up against the Chicago Cubs when Jake Arrieta takes the mound. The same would have been said for the Horned Frogs when Arrieta attended TCU for his sophomore and junior seasons.

Arrieta's 14 wins in 2006 led the NCAA and the right-hander recorded a 2.35 ERA, including a 1.12 ERA in Mountain West play. Arrieta posted a 9-3 record with a team-high 93 strikeouts during his final season in Fort Worth before he was selected by Baltimore in the 2007 MLB Draft.

RHP: Max Scherzer, Nationals, Missouri

Originally drafted in 2003 by his hometown Cardinals, Max Scherzer elected to attend the University of Missouri on a baseball scholarship, where he pitched from 2004-06. Scherzer earned Big 12 Pitcher of the Year honors in 2005 with a 9-4 overall record and 1.86 ERA. The right-hander also struck out 131 batters that season as a sophomore. Following the 2006 season, Scherzer became Mizzou's first player to be drafted in the first round when the Diamondbacks selected Scherzer with the 11th overall pick.

Scherzer replaces Nationals teammate Stephen Strasburg on the NL roster, who also pitched collegiately at San Diego State.  

RHP: Mark Melancon, Pirates, Arizona

Mark Melancon is another All-Star pitcher who elected to attend college after being drafted out of high school. Arizona legendary coach Andy Lopez recruited Melancon to the Wildcats program, where the pitcher helped the Wildcats to their first CWS since 1986. Melancon made 29 appearances on the mound to record a single-season freshman record.

The right-hander moved to a closer role for his sophomore season and recorded a single-season record 11 saves. Melancon still holds today the all-time save record with his 18 saves in a Wildcats uniform.

RHP: A.J. Ramos, Marlins, Texas Tech

The Marlins had four players named to the NL All-Star roster, but one name in particular will stand out in Lubbock, Texas. A.J. Ramos grew up near the Texas Tech campus and becomes the first Red Raider to be selected as a MLB All-Star. Ramos was a huge part of the weekend rotation for three seasons in Lubbock and recorded a 16-16 record during his time. Ramos tossed 254 innings and struck out 241 hitters, which is the sixth most in Texas Tech history.
