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.
Last year, the club experienced significant improvements as the season progressed, finishing with a 37-36 record in its final 73 games and 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). Notably, 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 promotions of Jorge Alfaro, J.P. Crawford, Rhys Hoskins and Nick Williams and the emergence of Luis García and Adam Morgan in the bullpen contributed to the overall second-half improvement.
In player development, the Phillies' domestic minor league affiliates collectively posted a .528 winning percentage in 2017. The combined winning percentage of .555 from 2015-17 is tied for first in all of baseball. And for the second year in a row, more Phillies minor league players (33) were named to midseason All-Star teams than any other organization. Last January, the club opened up a brand new year-round academy in the Dominican Republic. And in June, the club selected center fielder Adam Haseley out of the University of Virginia with its first round pick.
Heading into 2018, the Phillies spent their offseason seeking to improve the organization both on the field and off. The offseason began with the hiring of manager Gabe Kapler and a new major league coaching staff, in addition to the creation of a new advance scouting/player information arm of the baseball operations department at both the major and minor league levels. In November, the club promoted four pitchers to the 40-man roster: Seranthony Domínguez, Franklyn Kilomé, Ranger Suárez and José Taveras. In December, the club signed free agent relief pitchers Tommy Hunter and Pat Neshek to bolster the bullpen before inking free agent first baseman Carlos Santana later in the month. Off the field, the Phillies made significant additions to their international, pro and amateur scouting departments, while also continuing the expansion of the R&D department. In player development, there was a substantial increase in personnel and the announced launch of a second GCL team for 2018.
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
