Philip Diehl (Jerry Coli)

Pinstriped Profile: Phillip Diehl

The New York Yankees selected left-handed pitcher Phillip Diehl in the 27th round of the 2016 Major League Amateur Draft out of Louisiana Tech University. He was given a signing bonus of $70,000.

He was part of the same draft class as Blake Rutherford, Nick Solak, and Dom Thompson-Williams.


Diehl was assigned to the Rookie Pulaski Yankees of the Appalachian League. Diehl appeared in 14 games, 13 of those appearances out of the bullpen, and pitched to a 4-0 record with one save and a 2.56 ERA. He pitched 31 and two-thirds innings allowing just 23 hits, six walks and striking out 38 batters.

That strong performance earned him a promotion to the Class A short-season Staten Island Yankees of the New York-Penn League for one game at the end of 2016. He earned the victory in that game coming out of the bullpen and pitching two scoreless innings allowing one hit and striking out three batters.


Diehl found himself assigned to the Class A Charleston RiverDogs of the South Atlantic League. Diehl appeared mainly out of the bullpen but also made a handful of starts. He appeared in 28 games, five of which were starts. He posted a 9-3 record with a 3.16 ERA with two saves in 85 and one-third innings pitched. He allowed just 76 hits and struck out 101 batters. He only walked 26 batters calculating out to a 1.195 WHIP.

Scouting Report

Diehl is a lanky 6 foot 2 inches tall lefty who doesn’t throw hard. He suffered an elbow injury while at Louisiana Tech in 2015 but he’s bounced back from that injury without issue. His fastball is in the low-90s and he mixes it up with a slider and a changeup. He possesses great command of his pitches, throws strikes and works fast on the mound. He’s not afraid of contact and has been more effective out of the bullpen than as a starter.

2018 Outlook

Diehl will turn 24 during the season and should earn a promotion to the Tampa Tarpons of the advanced Class A Tampa Tarpons of the Florida State League. The Yankees will most likely keep him in the bullpen, but as in 2017, may start a few games depending on the team’s needs.
