DETROIT – The Detroit Tigers are bringing promising pitcher Jackson Jobe to the major leagues to strengthen their roster and compete for a playoff spot in the final week of the regular season.

The Tigers plan to nominate experienced right-hander Shelby Miller for the assignment.

The startling news suggests that the Tigers are preparing their roster for six crucial games this week and possibly a subsequent playoff series.

Jobe, 22, was selected No. 3 overall in the 2021 draft and is widely considered the best pitching prospect in all of baseball. He spent nearly the entire season at Double-A Erie before being promoted to Triple-A Toledo on short notice two weeks ago.

Jobe could be included in the Tigers’ playoff roster if they qualify for the postseason.

Miller, who turns 34 next month, was one of the Tigers’ most frequently used relief pitcher options for much of the season.

But while the Tigers’ bullpen was pushed to its limits in September, Miller pitched just four times and only walked one of the 21 batters he faced.

The Tigers held an option for Miller through 2025 worth at least $4.25 million. Instead, he will be a free agent again this winter.

Tigers ace Tarik Skubal is scheduled to start Tuesday night’s series opener against the Tampa Bay Rays. If necessary, he could also be back on the field in the season finale on September 29 against the Chicago White Sox.

In the four games in between, Tigers manager AJ Hinch is expected to manage his pitchers as if it were a playoff game: All hands on deck, including Jobe.

This story will be updated.
