DETROIT -- entered the season as a relatively unknown unranked pitcher in the Tigers' farm system -- a fifth-round Draft pick last year out of Middle Tennessee State with a big curveball, a fastball with good ride, some sporadic control issues and a thirst to learn about pitching.

Hamm wrapped up his first full pro season last week as the Tigers’ No. 7 prospect per MLB Pipeline, the top pitching prospect in the organization not named Jackson Jobe and potentially the next man behind Jobe to join the pitching pipeline to Detroit.

For a pitcher who talks about vertical movement on his pitches with ease, Hamm's career is on the rise. Nobody in the organization did more for his stock this season.

“It’s been awesome,” Hamm said last month between starts at High-A West Michigan. “Everything that I worked this offseason and after getting a little short stint after getting drafted last year, you want to put yourself in the position that I put myself into this year.”

As much as the Tigers have invested in high-end pitching prospects over the years, underrated hurlers like Hamm are where the organization makes its mark. He had a 5.31 ERA and 4.2 walks per nine innings in his junior season at Middle Tennessee and wasn’t even the highest-drafted pitcher from his program last year; right-hander Eriq Swan went to the Dodgers a round earlier.

The Tigers brought Hamm into their system and made a quick adjustment, getting him to throw more high fastballs.

“I’ve always been taught to throw fastball at the knees,” Hamm said. “Well, when I was throwing fastballs at the knees in college, it was riding belt high. So now being able to work at the top of the zone with the heater and then get back down, it has been a huge gain for me.

“First time I really put it to use was with the [Single-A Lakeland] Flying Tigers after getting drafted, just try to work up in the zone. I started missing bats with the fastball and I was like, ‘Oh wow, I’m throwing it where the hitter wants it, but it has that extra little bit at the top where they can’t get on top of it.’”

The other adjustment, with help from pitching coordinator Stephanos Stroop, was to add a slider to his arsenal of fastball, curveball and changeup. The slider has more horizontal movement than vertical, darting in on left-handed hitters and away from righties. Hamm picked it up quickly midway through Spring Training and worked it into his arsenal early.

Hamm dominated at High-A early in the season with a simple plan: Pound the top of the zone with fastballs to get ahead, change speeds, then set up the slider and curveball. He allowed just four runs over 37 2/3 innings in his first 10 starts, a 0.96 ERA with a .188 opponents' batting average. He then had to adjust in the second half as hitters became more aggressive.

“A lot of my success late in the season has come after throwing a first-pitch curveball for a strike and then throwing maybe a changeup off of it, so they’re now 0-2 without seeing a fastball and then the cards are in my hand,” Hamm said. “Just trying to reverse the roles on them now instead of just giving them heaters like I did at the beginning of the year has really helped me stay successful, stay true to myself.”

Hamm's goal for the offseason is to further hone those secondary pitches.

“Right now, if I was to write a scouting report against myself, I’m going to be the north-south guy and then I’m occasionally going to throw a changeup,” Hamm said. “So if I have a changeup and a slider, then I have four pitches and they’re all going in different directions. The slider’s definitely going to be something, especially going into this offseason where I can really hone in on making it more of a pitch that I can throw at any time.”
