Krol was drafted by the Oakland Athletics in the seventh round of the 2009 Major League Baseball Draft out of Neuqua Valley High School in Naperville, Illinois, despite not pitching in his senior year due to an alcohol-related offense. After missing time due to an elbow injury, Krol made his professional debut on August 27, starting for the AZL Athletics. After that, he made three appearances (one start) with the Low-A Vancouver Canadians. Krol played most of 2010 with Single-A Kane County Cougars, where in 24 games (23 starts), he went 9–4 with a 2.65 ERA, striking out 91 in 1182⁄3 innings, and was a mid and post-season all-star. He also made four starts for High-A Stockton at the end of the year, going 1–0. Krol missed the first three months with an elbow injury, and was pitching in a rehab assignment in the Arizona League before he was suspended for the rest of the season for a tweet that included a "gay slur along with some other offensive language". Krol began 2012 with the Ports as a starter, where in 15 starts, he went 1–7 with a 5.62 ERA. In late July, he was moved to the bullpen to reduce his projected innings pitched total and shined in that role, earning a promotion to the Double-A Midland RockHounds. In 29 total games (15 starts), he went 2–9 with a 5.20 ERA, striking out 89 in 97 innings.
Krol was acquired by the Washington Nationals in March 2013 as a player to be named later in the trade that sent Mike Morse to the Seattle Mariners, John Jaso to Oakland, and A. J. Cole and Blake Treinen to the Nationals. He was assigned to Double-A Harrisburg to begin the year, where he got off to a hot start. In 21 games with the Senators, he had a 0.69 ERA, striking out 29 in 26 innings.
He was called up to the majors for the first time on June 4, 2013. He made his major league debut the next day against the Mets, striking out the side in one scoreless inning of work. After a short stint with the Triple-A Syracuse Chiefs at the end of August, Krol returned to the Nationals for September. In 32 games with Washington, he went 2–1 with two holds and a 3.95 ERA, striking out 22 in 271⁄3 innings.
