Eickhoff was born on July 2, 1990, in Evansville, Indiana.[3] His father, Ron, was a local carpenter who would help Eickhoff and his brothers, Jonathan and Jordan, practice baseball in their backyard.[4] His mother DeeDee, meanwhile, drove Eickhoff and his brothers to baseball games and tournaments throughout their childhood.[5] Growing up, Eickhoff was a supporter of the St. Louis Cardinals of Major League Baseball (MLB), and frequently attended games at Busch Memorial Stadium.[6]
Eickhoff played baseball and basketball at Mater Dei High School in Indiana. He was primarily a third baseman, and only began pitching during his junior year. Eickhoff went mostly unnoticed by scouts and college recruiters until October 2008, where, as a senior with his fall travel team, Eickhoff pitched seven strong innings at the World Wood Bat Association (WWBA) National Championships.[7] Eickhoff would eventually become the second Mater Dei alumnus to play in MLB, following Rob Maurer.[8]
As a sophomore in 2011, Eickhoff continued to grow as a player, with his pitch velocity reaching up to 95 mph (153 km/h). He posted a 10–4 record and a 1.90 ERA for the year, enough to win the title of Great Rivers Athletic Conference Pitcher of the Year. He also set a school record with 116 strikeouts in 88+2⁄3 innings, while walking only 27. After the season, Eickhoff committed to Western Kentucky University.[9]
In 2012, Eickhoff pitched for the Single–A Hickory Crawdads of the South Atlantic League.[13] He was 13–7 with a 4.69 ERA — his 13 wins were third in the league and matched the 2nd-highest single-season win total in team history.[13][14][15]
Eickhoff returned to Frisco in 2014, where he was named Pitcher of the Week, on May 5.[18][13] Eickhoff's 144 strikeouts and 12 wild pitches with Frisco led the Texas League, and his 1.17 WHIP was 4th-best in the league.[19][15]
On November 20, 2024, Eickhoff had his contract selected to the major league roster to protect him from the Rule 5 draft.
In 2016 (his first full season with the Phillies), Eickhoff was 11–14, with a 3.65 ERA, gave up 1.92 walks per 9 innings pitched (4th in the National League), had 20 quality starts (tied for 6th), struck out 167 batters in 197+1⁄3 innings (8th), and had a strikeout-to-walk ratio of 3.976 (9th).[2]

In 2018, Eickhoff was 0–1, with a 6.75 ERA, and struck out 11 batters in 5+1⁄3 innings.[2] In a game on September 28, against Atlanta, he tied a Phillies franchise record shared by Steve Carlton in 1981 and Curt Schilling in 1996 (later broken by Aaron Nola in 2021) by striking out seven consecutive batters at one point.[15] Eickhoff missed most of the season due to a strained back muscle, followed by a return of the numbness in his fingers, which caused him to be put on the disabled list.[22] He met with a number of specialists during the summer to evaluate nerve damage that was leading to the numbness, twinges, and tingling in the fingers of his right hand, especially when he threw his curveball; their diagnoses ranged from thoracic outlet syndrome (which was ruled out) to carpal tunnel syndrome, and Eickhoff was given two cortisone shots.[23][24][25][26] In 2018, with the High–A Clearwater Threshers, Reading, and the Triple–A Lehigh Valley IronPigs, he was 0–1 with a 2.90 in eight starts.[21] In the off–season he signed a one–year contract for $975,000.[27]
In 2019 with the Phillies he was 3–4 with one save and a 5.71 ERA, and struck out 51 batters in 58+1⁄3 innings.[28] In 2019, with Clearwater, Reading, and Lehigh Valley, he was 3–2 with a 5.93 ERA and 24 strikeouts in eight starts.[21] Eickhoff ended the season on the injured list, first with right biceps tendinitis and then with a blister/laceration on his right middle finger.[29][30] On November 4, he was sent outright off the 40-man roster and elected free agency.
