TORONTO — Franklin Perez’s injury issues continue.

The Detroit Tigers' right-handed pitching prospect is expected to miss 4-to-6 weeks with right shoulder tendinitis, according to the team.

Perez, the No. 3 prospect in the farm system according to the Free Press, most recently threw two innings Monday afternoon in the team’s inaugural future stars game. The righty — who opened spring training in major league camp — had recovered from a shoulder trapezius spasm, which knocked him out of action early in spring.

Now, that blip in the radar appears to be something more serious.

The news is another blow to Perez’s standing as a prospect: His development took a serious hit in 2018 when he missed most of the season, first with a right lat strain sustained in spring training which kept him out three months, then with shoulder inflammation, which shut him down for the season in late July.

Perez, 21, was the centerpiece of in the trade that sent Justin Verlander to Houston on Aug. 31, 2017. In four minor league seasons, he has a 3.60 ERA and 1.22 WHIP in 57 games (43 starts). He had a 6.52 ERA in 19 1/3 innings in the minors last year.

The Tigers were elated with Perez’s progress this spring, but once again, will be left wondering if he will ever stay healthy enough to realize his full potential.
