Pitch Types  
FA: Four-Seam Fastball FT: Two-Seam Fastball FC: Cutter
CU: Curveball SL: Slider CH: Changeup
FS: Splitter

 

Tuesday, 8:05 PM – Bud Norris

(click to enlarge)

Norris has a compact delivery and an over-the-top release point. His fastball sits in the low 90’s and touches 95 MPH. He also throws a slider in the mid 80’s and a changeup in the low 80’s. Each of his pitches have lost a tick of velocity this season, but have remained effective. The slider is his big swing-and-miss pitch, driving a well above average overall whiff rate. Norris has cut down on his walks a bit this year, leading to improved numbers.

 

Wednesday, 8:05 PM – J.A. Happ

Happ utilizes a diverse repertoire. His fastball sits around 90 MPH, and occasionally shows decent arm-side movement. He also throws a changeup and slider in the low 80’s and a slow curve in the mid 70’s. He does not miss many bats, but still manages to consistently produce an above average strikeout rate. After a few strong seasons, his high walk rate and fly ball tendencies appear to be catching up to him a bit this year.

 

Thursday, 2:05 PM – Jordan Lyles

(click to enlarge)

The 20-year-old Lyles throws his fastball right around 90 MPH, and commands it very well. His low 80’s changeup shows good arm-side movement. He also throws a sharp, upper 70’s curveball with good downward break. Both off-speed pitches are plus offerings and have missed plenty of bats in his limited major league experience. Lyles’ strikeout rate in his three career starts has been right around league average, but all 12 of his punchouts have come by way of a swing. Expect that number to improve as he begins to catch a few more hitters looking.
