Kline attended Governor Thomas Johnson High School in Frederick, Maryland. In his senior year, in 2009, he experienced an increase in velocity, reaching 95 miles per hour (153 km/h), which drew attention from scouts. He finished his senior year with a 6–1 win–loss record, a 0.51 earned run average (ERA) and 79 strikeouts in 41 innings pitched. The Boston Red Sox selected Kline in the sixth round, with the 198th overall selection, of the 2009 MLB draft. He opted not to sign, as he had already committed to attend the University of Virginia on a college baseball scholarship.
With the Virginia Cavaliers baseball team, Kline was used as a relief pitcher in his freshman and sophomore years. In his sophomore year, Kline recorded 18 saves, the third most in college baseball, and tying the Cavaliers' record and setting an Atlantic Coast Conference record. That year, he was also named a first-team All-American. As a junior, Kline had a 7–3 win–loss record, a 3.56 ERA, and 94 strikeouts in 93 2⁄3 innings, with 15 of his 16 appearances as a starting pitcher.
The Baltimore Orioles selected Kline in the second round, with the 65th overall selection, of the 2012 MLB draft. He signed with the Orioles, receiving a signing bonus just below $800,000. He made his professional debut after signing with the Aberdeen IronBirds of the Class A-Short Season New York–Penn League, where he compiled a 4.50 ERA in 12 innings.
Kline pitched for the Delmarva Shorebirds of the Class A South Atlantic League in 2013 where he was 1–2 with a 5.86 ERA in seven starts. He began the 2014 season with the Frederick Keys of the Class A-Advanced Carolina League, and was named their Opening Day starting pitcher. In August, the Orioles promoted Kline to the Bowie Baysox of the Class AA Eastern League. In 26 starts between both teams, he was 8–8 with a 4.08 ERA. Kline spent the 2015 season with Bowie. By training with a weighted ball in the offseason, as suggested by teammate Tyler Wilson, Kline's fastball velocity improved from 90 to 94 miles per hour (145 to 151 km/h) to 93 to 97 miles per hour (150 to 156 km/h). In eight starts, he pitched to a 3–3 record and a 3.66 ERA.
In October 2015, Kline underwent Tommy John surgery. He missed the 2016 season, and had a follow-up surgery in March 2017, forcing him to miss all of that season as well. He returned to Frederick in 2018 as a relief pitcher. The Orioles added him to their 40-man roster after the season.
He opended the 2019 season with the Triple-A Norfolk Tides. On April 20, he was recalled to the major league roster for the first time, as the 26th man for a double-header versus the Minnesota Twins. He made his debut that night, recording two innings in relief.
