Born on September 16, 1992, in Rock Falls, Illinois, Junis has built a durable major league career since making his debut with the Kansas City Royals in 2017. He resides in Scottsdale, Arizona, with his wife Brianne and their three children.
Early Life and Background
Junis grew up in Rock Falls, Illinois, where he attended Rock Falls High School and graduated in 2011. During his high school career, he distinguished himself as a two-sport athlete, earning all-state honors in both baseball and basketball. As a senior in basketball, he averaged 19 points per game, showcasing his athletic versatility. On the baseball diamond, Junis demonstrated significant pitching promise, throwing a fastball in the 88-92 mph range while posting a 1.10 earned run average and recording 93 strikeouts. He also excelled at the plate, batting .485 with 54 runs batted in during his final high school season.
Despite receiving a scholarship to play college baseball at North Carolina State University as both an infielder and pitcher, Junis chose to pursue professional baseball. He had been rated as a fourth-round prospect but fell to the 29th round of the 2011 MLB Draft, where the Kansas City Royals selected him. Junis signed with the Royals for a $675,000 signing bonus, forgoing his collegiate commitment.
Path to Major League Baseball
After signing with the Royals in 2011, Junis began his professional career in the minor leagues. He debuted in 2012 with the Burlington Royals of the Pioneer League, where he posted a 2-2 record with a 4.15 earned run average in seven appearances. The following season proved more challenging as he went 2-6 with a 7.39 earned run average for the Idaho Falls Chukars, though he still recorded 55 strikeouts to rank eighth in the Pioneer League.
Junis steadily improved through the Royals farm system. In 2014 with the Lexington Legends, he compiled a 9-8 record with a 4.30 earned run average while finishing fifth in the South Atlantic League with 10 hit batsmen. He continued his development in 2015 with stops at Wilmington Blue Rocks and Northwest Arkansas Naturals, combining for a 5-12 record across 27 starts. His 2016 campaign marked a breakthrough when he went 9-7 with a 3.25 earned run average between Northwest Arkansas and Omaha Storm Chasers, ranking third in the Texas League in earned run average and sixth in strikeouts. He earned Texas League Mid-Season and Post-Season All-Star honors that year and was added to the Royals 40-man roster following the season.

Kansas City Royals Era (2017-2021)
Junis made his major league debut on April 12, 2017, with the Kansas City Royals. He experienced the typical ups and downs of a rookie, being recalled and optioned multiple times before securing a permanent roster spot on August 14. Over his final 20 appearances including 16 starts, Junis posted a remarkable 9-3 record with a 4.30 earned run average, finishing his debut season strong.
The 2018 season marked Junis first full major league campaign as a starter in the Royals rotation. He made 30 starts and compiled a 9-12 record with a 4.37 earned run average and one complete game. He led the American League with 15 hit batsmen, setting a franchise record for a single season. He also ranked eighth in the league in walks per nine innings and tenth in strikeout-to-walk ratio. In 2019, Junis made 31 starts for Kansas City, posting an 8.4 strikeout-per-nine-innings rate and a 5.24 earned run average across 175 and one-third innings. He became the first pitcher in the major leagues to win at least nine games in each of his first three seasons since Masahiro Tanaka from 2014 to 2016.
The 2020 and 2021 seasons presented challenges for Junis with injuries. In the shortened 2020 campaign, he appeared in only eight games including six starts, compiling an 0-2 record with a 6.39 earned run average and spending time on the injured list twice. He made 16 appearances with six starts in 2021, posting a 5.26 earned run average with 41 strikeouts in 39 and one-third innings, again dealing with injuries that landed him on the injured list. Following the 2021 season, Junis was outrighted off the Royals 40-man roster and elected free agency after rejecting the assignment.
San Francisco Giants Tenure (2022-2023)
On March 14, 2022, Junis signed a one-year contract worth $1.75 million with the San Francisco Giants.

He became a valuable member of the Giants bullpen, making 40 appearances and recording a 3.87 earned run average with 96 strikeouts across 86 innings pitched. His improved strikeout rate and lower earned run average demonstrated his ability to adapt from a starting role to relief work.
Milwaukee Brewers and Cincinnati Reds (2024)
On February 7, 2024, Junis signed a one-year contract worth $7 million with the Milwaukee Brewers, which included a mutual option for the following season. He made just one start before being placed on the injured list with a right shoulder impingement on April 6.

He was transferred to the 60-day injured list on May 6 before being activated on June 21. Despite the limited opportunities, he posted an impressive 2.42 earned run average with 19 strikeouts in 26 innings across 10 appearances.
The Brewers traded Junis to the Cincinnati Reds on July 30, 2024, in exchange for Frankie Montas, with cash considerations also included in the deal. He performed well with his new team, recording a 2.85 earned run average with 32 strikeouts over 41 innings in 14 appearances.

He delivered his best results in years, compiling a 4-1 record with a 2.97 earned run average and 55 strikeouts across 66 and two-thirds innings.
