Rozema was 15-7 with a 3.09 ERA in 28 starts and 218.1 IP as a 20-year-old rookie in 1977. He had 16 complete games. He had 5.7 WAR.
That's a heck of a rookie season, especially for a 20-year-old. What was remarkable about Rozema was that he almost never struck anyone out, but still managed to have good ERAs and didn't allow a ton of hits. He only struck out 92 hitters as a rookie and
his career strikeout rate was only 3.6 K/9. He almost never walked anyone. He only walked 34 hitters as a rookie and had a career walk rate of only 2.1 BB/9. Rozema had one of the lowest strikeout rates in major league history for a pitcher with over 1,000
career innings.
Interestingly, Mark Fidrych was almost a clone of Rozema in that he rarely struck out anyone but didn't walk anyone either. Fidrych's career K rate was 3.7 K/9 and walk rate was 2.2 BB./9.
Both Fidrych and Rozema were sort of the ultimate "pitch to contact" pitchers but they were really good at not getting hit hard and keeping the ball down in the zone.
Rozema had a good season in 1978 as well (3.14 ERA in 28 starts with 4.0 WAR) and was pitching well in 1979 but his arm got hurt and he became more of a long reliever/spot starter after that. All those complete games at a young age took an early toll on him.
It was interesting that the Tigers in '76 and '77 had 2 top young pitchers come up who almost never struck out anyone or walked anyone. They weren't kid flamethrowers but pitched more like crafty veterans as 20-year-olds. You'd think with having such a low
K rate they would haven't been able to sustain success, but to be fair to Rozema, he had a solid 10-year-career (he became a decent long reliever after his arm couldn't handle starting anymore) and never really had a bad season. Fidrych could never stay healthy
after his rookie season so we really don't know how he would have turned out over a longer period of time.
As we know, Fidrych was quite a character, but Rozema was as well. Having those 2 guys in the clubhouse must have been wild. Trammell and Whitaker had fun as well.
If Fidrych and Rozema had stayed healthy to go along with Jack Morris coming up in 1978 and Dan Petry coming up in 1979 (plus Milt Wilcox being a decent #5 guy for several years) the Tigers might have had one of the better rotations in baseball and might have
made the playoffs before 1984. Fidrych and Rozema getting hurt kind of knocked them back pitching-wise for a few years. (Plus some of the other Tigers' top pitching prospects back then didn't develop...remember Bob Sykes, Pat Underwood, Kip Young, Steve
Baker, Steve Grilli, and Sheldon Burnside? They were all terrible. The Tigers had to rely on acquiring crusty veterans to fill out the rotation).
