Olsen Field at Blue Bell Park is a baseball stadium in College Station, Texas, that is home to the Texas A&M baseball program. The stadium was dedicated on March 21, 1978, and is named in honor of C. E. "Pat" Olsen, a 1923 graduate of Texas A&M University and a former baseball player in the New York Yankees farm system. Olsen Field has served as an NCAA regional site five times and had its 1999 regional attendance ranked second with 53,287. The first NCAA Regional Tournament held at Olsen Field was in 1989.
In 2004 Sports Illustrated on Campus ranked Olsen Field "the best college baseball venue". Aggie baseball fans called RAggies have a reputation of fiercely "ragging" opponents.
Olsen Field underwent a major renovation that began on June 7, 2011, funded in part by donations from the owners of Blue Bell Creameries, based in nearby Brenham. In return, Blue Bell gained naming rights. Some new features of the stadium included an expanded concourse and concessions area, luxury suites, a new press box, club seating, two grass berms, expanded locker rooms and coaches offices, a student athletic center, and extended seating closer to the field. However, the seating capacity was decreased from 7,000 to 5,400 to accommodate the changes (although with standing room only will still hold over 7,000). Olsen Field reopened on February 17, 2012 for the first game of the 2012 baseball season even though some projects were not completely finished; the remaining work was completed on non-game days.
In 2015, the Aggies ranked 7th among Division I baseball programs in attendance, averaging 4,857 per home game.
