Matt Klentak was named vice president & general manager of the Phillies on October 26, 2015, at 35 years old, making him the youngest GM in club history.
In 2016, the Phillies improved their win total by eight games (from 63 to 71 wins), which tied for the sixth-best improvement in MLB from 2015 to 2016. Notably, the starting pitchers collectively recorded an improvement of 8.1 WAR from 2015 to 2016, representing the most improved starting rotation in all of baseball over that time. The club also reduced the average age of the Opening Day roster from 29.6 in 2015 (the seventh-oldest) to 28.3 in 2016 (the third-youngest). This age reduction of 1.3 years ranked second in all of baseball.
In 2017, the club experienced significant improvements as the season progressed, finishing with a 37-36 record in its final 73 games, including a 15-13 mark in September. This improvement was driven principally by the performance of the team's offense, which scored nearly a full run per game more after the All-Star break (4.77) than before (3.82). This improvement also corresponded with a reduction in the average age of the team's roster from Opening Day (28.67) to August 31 (27.03).
The Phillies continued their youth movement in 2018 and opened the season with the youngest roster in all of baseball (26.9). Led by first-year manager Gabe Kapler, the team spent 34 days in first place through mid-August, and the overall 14-game improvement (from 66 wins to 80 wins) represented the fifth-best mark in Phillies franchise history. The team was led by a starting rotation that featured Aaron Nola and his third place Cy Young Award performance, plus free agent acquisition and former Cy Young Award winner Jake Arrieta. Collectively, the starting rotation produced 15.5 WAR, which was the third-best mark in the National League. The bullpen, whose collective 4.1 WAR ranked fourth in the NL, received a major boost with the recall of Seranthony Domínguez in May, and the offense was powered by 25-year-old Rhys Hoskins and free agent signing Carlos Santana. Wilson Ramos, acquired in a late-July trade from the Rays, also had a significant impact on the offense down the stretch.
In player development, the Phillies' domestic minor league affiliates collectively posted a .549 winning percentage in 2018, with four affiliates qualifying for the playoffs. Phillies minor league pitchers posted a collective 3.49 ERA, which ranked third in professional baseball, and the organization's .981 fielding percentage was the best in baseball. The combined winning percentage of .553 from 2015-18 also represents the best mark in all of baseball. In June, the club selected third baseman Alec Bohm from Wichita State University with its first-round pick.
Heading into 2019, the Phillies spent their offseason seeking to improve both the team's run production and run prevention. The first move of the offseason was a trade with Seattle in early December in which the Phillies acquired two-time All-Star shortstop Jean Segura and relief pitchers Juan Nicasio and James Pazos in exchange for Santana and J.P. Crawford. The inclusion of Santana in the trade allows Hoskins to shift from left field to first base in 2019, which paved the way for the signing of outfielder and former NL MVP Andrew McCutchen later in December. The bullpen was further strengthened with the acquisition of José Alvarez from the Angels and the free agent signing of David Robertson. In February of this year, the club acquired All-Star catcher J.T. Realmuto and signed All-Star right-hander Nola to a four-year contract with a club option for 2023. On March 1, the Phillies landed free agent outfielder Bryce Harper, signing the 2015 NL MVP and six-time All-Star to a 13-year contract. The club also promoted three players to the 40-man roster in November: SS Arquímedes Gamboa, RHP Édgar García and RHP Adonis Medina.
Before joining the Phillies, Matt spent four years (2012-15) as assistant GM of the Los Angeles Angels under GM Jerry Dipoto. During his tenure with the Angels, the club won the American League West Division title in 2014 and averaged 87 wins per season. Prior to his time with Los Angeles, Matt worked under Andy MacPhail as director of baseball operations for the Baltimore Orioles for four years (2008-11), where he assisted in scouting, player development, contract negotiations and the construction and management of the 40-man roster. While in Baltimore, MacPhail and Klentak acquired players who would play significant roles in helping the club reach the postseason in 2012, 2014 and 2016.
Matt's resume also includes working four years (2004-07) in Major League Baseball's Labor Relations Department, where he served as a primary contact for club personnel with respect to the interpretation of the Major League Rules, the Collective Bargaining Agreement and other contractual and financial industry practices. He was a key member of the MLB collective bargaining team that successfully negotiated a second consecutive CBA without a work stoppage in 2006. He also spent the 2003 season in the baseball operations department of the Colorado Rockies, where he gained experience in video and advance scouting, coordinated the inflow of all amateur scouting reports and authored several baseball and financial analyses throughout the season.
A native of Medfield, Mass., Matt earned an economics degree in 2002 from Dartmouth College, where he was a four-year baseball letterman, three-year starting shortstop and team captain his senior year. The Big Green won two Ivy League Red Rolfe Division championships (2000 and 2001) during his playing days. Matt and his wife, Lauren, have two young daughters.
