The Detroit Tigers swept a doubleheader from the hapless Colorado Rockies at Coors Field on Thursday, raising their American League-best record to 25-13 — the second-best record in MLB, just a half-game behind the Los Angeles Dodgers at 25-12.

The Rockies are the worst team in baseball, with only six wins in 37 games. But from the Tigers’ point of view, winning a doubleheader by a combined score of 21-3 over any team is an accomplishment.

It would seem that most everything is going right for Detroit. The Bengals are off to a scorching start following their incredible late-season surge last year that carried them from a sub-.500 record in mid-August into the playoffs.

But the Tigers’ situation is about to get better. Injured reliever John Brebbia, who had allowed just one earned run in nine innings before going on the injured list with a triceps strain, is now set to return to the big league club on Friday, according to a report by Evan Woodbury of the Detroit-area news site MLive.

To make room for the righty with the 1.00 ERA, the Tigers optioned 26-year-old rookie right-handed sidearmer Chase Lee to Triple-A Toledo. Lee, in 4 1/3 innings over five games before Thursday’s action, had yet to allow a run — giving him an ERA of 0.00.

Lee, who made his major league debut on April 22, got the word that he was headed back to the minors between games of Thursday’s doubleheader, after he pitched two innings in the first game and allowed his first big league run, raising his ERA to 1.42.

Lee has an unusual origin story. In 2019, he made the Alabama baseball team as a walk-on, after previously quitting baseball to study aerospace engineering at the university.

His change of heart to give baseball a second try worked out. He was drafted by the Texas Rangers two years later, in the sixth round. After three years in the minor leagues, Texas traded Lee at last year’s trade deadline to the Tigers with another prospect for reliever Andrew Chafin.

Less than one year later, Lee made his major league debut.

The Tigers called up outfielder Brewer Hicklen to take Lee’s roster spot, but with Brebbia’s anticipated return Friday, Hicklen is expected to be sent back down.
