Knebel was born in Denton, Texas[1] to parents Jeffrey and Melissa Knebel and grew up in Bastrop County, Texas. He attended Bastrop High School, where he was a three-year letter winner and a former district MVP in baseball. He was also a member of the school's basketball team. He is a graduate of Georgetown High School, where he moved for his senior season.[2]
Knebel was again the Longhorn closer in 2012, finishing the year with nine saves and a 2.08 earned run average.[3] Though unable to match the accolades of his freshman season, he again earned first-team All-Big 12 honors.[3]
Knebel was suspended from the Longhorns twice in 2013, once for violating team rules and once for providing a urine sample to help a teammate beat a drug test.[6]
In May 2017, Knebel became the permanent closer for the Brewers, taking the job from a struggling Neftalí Feliz.[citation needed] On June 22, Knebel set the MLB record for most consecutive appearances with at least one strikeout by a relief pitcher at 38. The record was previously set in 2014 by Aroldis Chapman with the Cincinnati Reds. On July 19, Knebel's streak ended at 45 games after failing to record a strikeout in a blown save against the Pittsburgh Pirates.[citation needed]
Knebel injured his left hamstring while pitching on April 5, 2018, against the Chicago Cubs and was placed on the disabled list.[13] He was activated on May 9.[14] However, Knebel struggled over his next 3 months with the Brewers, and he was demoted to the Colorado Springs Sky Sox on August 24 after compiling a 2–3 record with a 5.08 ERA in 41 appearances.[15] He was brought back up on September 2,[16] and closed out the regular season in dominant fashion with 16 consecutive scoreless appearances, including 2 wins, 2 saves, and 6 holds.[17] In the 2018 postseason he posted a 0.90 ERA in 10 innings, giving up his lone run in a save of NLCS Game 1. [18]
Shortly after 2019 opening day, Knebel was dealing with soreness in his right elbow. It was eventually revealed that his right elbow had a torn UCL, which needed Tommy John surgery, putting Knebel away for the rest of 2019.[19] On December 2, Knebel was designated for assignment by the Brewers.
In the shortened 2020 season, Knebel returned and recorded a 6.08 ERA in 13+1⁄3 innings over 15 games.[20]
Los Angeles Dodgers
On December 2, 2020, the Brewers traded Knebel to the Los Angeles Dodgers in exchange for Leo Crawford.[21]
On May 2, 2021, Knebel was placed on the 60-day injured list with a right lat strain, an injury that kept him sidelined until August 10.[22] As a result of the injury he only appeared in 27 games for the Dodgers in 2021, including four appearances as an opener, and finished with a 4–0 record, 2.45 ERA, three saves and 30 strikeouts.[20] In the postseason, he appeared in seven games (including two as an opener), pitching 52⁄3 innings and allowing two runs on five hits and one walk while striking out 11.[20]
Philadelphia Phillies
On December 1, 2021, Knebel signed a one-year contract with the Philadelphia Phillies.[23] In 2022, Knebel made 46 appearances for the Phillies, registering a 3–5 record and 3.43 ERA with 41 strikeouts and 12 saves in 44+2⁄3 innings pitched. On August 21, 2022, Knebel was placed on the 60–day injured list with a torn shoulder capsule, and missed the remainder of the season.[24] He became a free agent following the season.

On February 13, 2024, Knebel signed a minor league contract with the Chicago White Sox.[25] In 12 appearances split between the rookie–level Arizona Complex League White Sox, High–A Winston-Salem Dash, and Triple–A Charlotte Knights, he accumulated a 5.91 ERA with 12 strikeouts across 10+2⁄3 innings pitched. Knebel was released by the White Sox organization on August 1.[26]
