The early years (1879–1958)

Baseball is among the first organized sports played at Texas A&M, and what was then A&M College of Texas fielded its first club in 1879.^[3] The first games were played between members of Company A and Company B of the Corps of Cadets.^[4] It's not surprising baseball started so early, considering that Texas A&M and Major League Baseball were both founded in 1876, and it was one of America's most popular sports of the period. The team played many of its earliest games against Galveston, Bryan, Baylor, Navasota, and Calvert. Games were limited by what town could be reached by train or horse. Most of the teams didn't have uniforms or even a real field. The same train tracks that run by Olsen Field today used to carry the team to its games. By 1907, the Cincinnati Reds had stopped off in College Station and beat A&M 9-0, scoring all 9 runs in the third inning, when, "our boys went to pieces."^[5] Seventeen head coaches led A&M baseball from 1904 to 1958, including football coaches Charley Moran, Dana X. Bible, and Homer Norton. During this period, A&M finished with a 626–469–27 record (.572 winning percentage), claimed seven Southwest Conference titles, and made their first trip to the College World Series in 1951. In 1951, led by Beau Bell, the Aggies won a three-game series in the District VI playoffs over Arizona and advanced to the College World Series. In the 1951 College World Series, Texas A&M defeated Ohio State 3–2 in a first-round elimination game to give the Aggies their first College World Series win.

Tom Chandler era (1959–1984)

Tom Chandler came to Texas A&M as an assistant to head coach Beau Bell in 1958. He took over as head coach in 1959 and immediately won the Southwest Conference championship in his first year. Over the next 25 years at the helm, Chandler led the Aggies to four more conference championships, eight NCAA postseasons, and an appearance in the 1964 College World Series. His teams finished 660–329–10 (.667 winning percentage). Chandler was honored for his accomplishments by being inducted into the American Association of Baseball Coaches Hall of Fame. His jersey is now displayed on the left-field wall at Olsen Field in recognition of his contributions. Tom Chandler was born on March 19, 1925, in Greenville, Texas. He attended Dallas public schools and graduated from Adamson High School in 1943. He then attended Arkansas A&M for two years in the Marine V-12 program. In 1946, he graduated from the Marine Corps Officers School. He served as a member of the Marine Corps Honor Guard that presented the colors at the funeral of President Franklin D. Roosevelt in April 1945.

Mark Johnson era (1985–2005)

Mark Johnson, an assistant under Chandler, assumed head-coaching duties in 1985 and guided the program for just over two decades. During that time, his teams put together a win–loss record of 876–431–3 (.670 winning percentage) and made College World Series appearances in 1993 and 1999. Johnson's highly ranked teams and powerful offenses in the late 1980s and throughout the 1990s brought excitement and increased attendance to Olsen Field. His #7 jersey hangs on the right-field wall at Olsen Field in honor of his service to A&M. Johnson's 876 wins are the most in Texas A&M history. Johnson led the Aggies to a 37–29 (.561) postseason record in 13 appearances.

In 1989, the Aggies put together a 58–7 record (17–4 in SWC play) and were SWC co-champions. The Aggies won the SWC tournament and hosted a regional at Olsen Field, which included Jackson State, BYU, South Alabama, and number-12 LSU. The Aggies exploded in the first three games, outscoring their opponents 65–13 before they were upset by LSU twice, ending one of the most remarkable seasons in A&M history. Despite not advancing to the College World Series, the Aggies finished the year number two overall in the final Baseball America poll (behind Wichita State, winner of the CWS).^[6] The Aggies defeated number-three Texas four out of five times (with two wins coming on walk-off home runs), including twice in the SWC tournament.

Johnson led the Aggies to the College World Series in 1993. The Aggies won the Southwest Conference championship and swept through the Central I Regional in College Station (defeating Yale, Lamar, UCLA, and North Carolina) at Olsen Field to advance to Omaha for the third time. A&M defeated Kansas, 5–1, for the second CWS win in A&M history. Notable stars on the team included Jeff Granger (who holds the single-game strikeout record at A&M with 21), Brian Thomas, Chris Clemons, Trey Moore, and Kelly Wunsch.

The Aggies again advanced to the College World Series in 1999, led by Daylan Holt, Steven Truitt, John Scheschuk, Dell Lindsey, and Casey Fossum. In the College Station regional, the Aggies lost to Long Beach State in game 2 before defeating Ole Miss and Long Beach State twice to advance to the super regionals, where they faced number-17 Clemson. The Aggies defeated Clemson in a best of three series, 2–1, earning the team's fourth trip to the College World Series.

Rob Childress era (2006–2021)

In 2006, Texas A&M hired Nebraska associate head coach and pitching coach Rob Childress to take over the program. After struggling to a losing record his first year, Childress guided the Aggies to a 597–306–2 (.660) record, two Big 12 championships (2010 and 2011), one Southeastern Conference championship (2016), and College World Series appearances in 2011 and 2017. Childress led the Aggies to the postseason 13 years in a row (2007–2019, the longest streak in Aggie history).

The Aggies advanced to the 2011 College World Series, led by Michael Wacha, Ross Stripling, John Stilson, Tyler Naquin, Jacob House, and Matt Juengel. A&M faced Missouri in the final game of the 2011 Big 12 Conference baseball tournament. Missouri took an early 6–0 lead. The Aggies fought their way back, and while down 9–8 in the bottom of the 9th, Gregg Alcazar tied the game on a 3-2, 2-out, RBI single to send the game to extra innings. The Aggies capped off the rally by winning it in the bottom of the 10th with a walk-off home run by Andrew Collazo, earning him the award of Most Outstanding Player. Jacob House, Kevin Gonzalez, Tyler Naquin, and Michael Wacha were named to the All-Tournament team.^[7] Texas A&M won the College Station regional with wins over Wright State, Seton Hall, and Arizona to advance to the super regional at Tallahassee to face the fifth national seed, Florida State. A&M won the first game 6–2, but was blasted in game 2, losing 23–9. The Aggies won the rubber match 11–2 to advance to the College World Series. The Aggies lost to eventual champion South Carolina in a very close game, 5–4.^[8]

Following a 2021 season that saw the Aggies finish in last place in the SEC, Athletic Director Ross Bjork announced that the school would not renew Childress' contract for 2022. Childress's 622 victories ranked third in school history at the time of his dismissal.^[9]

Jim Schlossnagle era (2022 - present)

On June 9, 2021, Jim Schlossnagle was named the head baseball coach of the Aggies.^[10] The Schlossnagle-led Aggies had a regular-season record of 35–17 and finished first in the SEC West in his first season at the helm, earning Texas A&M the number-five national seed. In the College Station regional, A&M hosted Oral Roberts, Louisiana-Lafayette, and TCU. The Aggies and Horned Frogs met in the regional final with the Aggies beating Schlossnagle's former team 15–9 to advance to the super regionals and host the 12th-seeded Louisville Cardinals. Texas A&M won both games against Louisville to advance to their seventh College World Series. In the College World Series, Texas A&M lost their opener to Oklahoma, 13-8, but won their next two games against Texas^[11] and Notre Dame^[12] to advance to the bracket-1 final against Oklahoma.
