Oakland Athletics edit

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.^[1] He was selected despite not pitching in his senior year due to being suspended for the entire season for an alcohol-related offense, his second violation of the district athletic code of conduct (his first violation, in his junior year, led to a seven-game suspension).^[2][3]

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—more than two months—for a tweet that included a graphic "gay slur along with some other offensive language".^[4][5][6]
