He was drafted by the Cleveland Indians in the 34th round of the 2006 Major League Baseball draft and his high school coach said "Obviously he has the talent to play at the next level. It's not much of a surprise to me that he got drafted." He chose not to sign with the Indians because of the low round and, even though he had signed a letter of intent to Texas Tech University, he chose instead to attend Grayson County Community College in the hopes of being drafted again the next year. In 10 appearances for Grayson, he was 6–1 with a 2.93 ERA and struck out 48 batters.

He was drafted in the 33rd round of the 2009 Major League Baseball draft by the Oakland Athletics, but chose to return to Arkansas for his senior season. Bolsinger began the 2010 season as the team's closer and earned a spot on the National Collegiate Baseball Writers Association "Stopper of the Year Watch List."

  ## Houston Astros lawsuit
  
  In February 2020, following MLB's findings in the Houston Astros sign stealing scandal, Bolsinger filed a lawsuit against the Houston Astros for personal damages to his career. Additionally, he is demanding that the Astros donate their $31 million in 2017 postseason bonuses to charity. Bolsinger authored an opinion article in The Washington Post explaining his reason for suing the Astros. Curiously, he filed the lawsuit in California despite there being no connection between Bolsinger, the Astros, or California. Judge David Cowan of the Los Angeles Superior Court dismissed the lawsuit. A refiling in Texas led to a subsequent nonfiling by August 2021, which meant the case was dismissed without prejudice.
