Jason Flach reached AAA after being undrafted out of college.
After going 6-7 with a save and a 3.77 ERA his last year at the University of the Pacific, he was signed by the Atlanta Braves as an undrafted free agent. He was 4-1 with 11 saves, 2.26 ERA and 1.04 WHIP that summer for the Eugene Emeralds, fanning 68 in 59 2/3 IP. He was third in the Northwest League in saves, behind Jeff Kubenka and Mick Pageler and was three shy of the top 10 in strikeouts despite being strictly a reliever. Pageler was named the league's All-Star right-handed reliever.
Despite that success, he was back in Eugene a year later and was still good (4-3, 5 Sv, 2.97, 51 K in 39 1/3 IP). He tied D.J. Johnson for sixth in the NWL in saves. He split 1998 between the Danville Braves (5-5, Sv, 3.14, 108 K in 106 IP) and Greenville Braves (0 R in 1 1/3 IP, 3 H, 4 K). He was 3-5 with a save and a 3.69 ERA for the Melbourne Monarchs in the 1998-1999 Australian Baseball League. He was 5th in the league in ERA, led in innings (4 2/3 over Phil Brassington) and was second with 74 strikeouts (7 behind Matt Herges).
In the summer of 1999, Flach was with the Myrtle Beach Pelicans (9-4, 3.07) and Greenville (1-2, Sv, 6.63). He tied Winston Abreu and Will Fleck for second among Braves farmhands in wins, trailing Jimmy Osting. He ended his career in 2000 with Greenville (4-6, 4.33) and the Richmond Braves (2-0, 5.12). He had gone 29-21 with 18 saves and a 3.59 ERA in 157 games as a pro (41 starts).
