Lauer and Priester were very differently viewed pitchers coming up. Both were 1st round picks but Priester came with a lot more prospect pedigree than Lauer. Priester was pretty much a consensus Top 100 prospect for multiple years before debuting while Lauer was more in the teens in a Top 30 org guy.
Priester had good marks for breaking pitches and command but his FB lagged behind which is why he struggled once he got to MLB. He doesn't even throw a four seamer anymore ditching it completely for more sinker usage and his new cutter which is an improving pitch.
Priester before June 10th - 13% cutter usage, 11 G, 55.2 IP, 3.88 ERA, 4.09 xERA, 4.62 FIP, 4.43 xFIP, 4.71 SIERA, 15% K-rate, 11% BB-rate
Priester starting June 10th - 22% cutter usage, 10 G, 58.2 IP, 2.45 ERA, 3.15 xERA, 3.44 FIP, 3.11 xFIP, 3.20 SIERA, 24% K-rate, 5% BB-rate
