DETROIT >> Long day. Regrettable day. Forgettable day.

The Tigers lost both ends of a doubleheader Saturday against the Central Division rival Twins — 11-5 in 12 innings in the opener and 4-1 in a lackluster nightcap.

They came into Game 2 with the scars from the seven-run, 12th inning atrocity still fresh. They also came in with a depleted bullpen and a starting pitcher, Matt Manning, called up from Triple-A Toledo as the 27th man, who hadn’t pitched in nine days.

The Twins weren’t much better off, playing without the starting left side of their infield (injured shortstop Carlos Correa and third baseman Royce Lewis) and starting outfielder Max Kepler.

Plus starting Triple-A right-hander Simeon Woods Richardson, who had two big-league starts under his belt — his big-league debut against the Tigers in 2022 and one last season. He’d fared poorly early on at St. Paul, also, allowing seven earned runs in eight innings.

Manning pitched into the seventh inning, which was imperative, but a solo home run by Edouard Julien in the third inning and a two-run homer by former Tiger Willi Castro in the sixth dug a hole the scuffling Tigers’ offense couldn’t climb out of.

The home run balls vexed Manning in spring training, too, and were a prime factor in him not winning a spot in the rotation. Six of the eight hits he allowed in 16 spring innings were homers.

Otherwise, Manning pitched very well Saturday. He posted seven strikeouts and got 12 whiffs on 50 swings. He also got 18 called strikes, 12 with his four-seam fastball.

Lefty Joey Wentz blanked the Twins the last 2.1 innings.

But the bats never heated. They were dominated by Twins starter Joe Ryan in Game 1 (12 strikeouts, one earned run) and couldn’t get to Woods Richardson in the nightcap.

Woods Richardson stymied the Tigers for six innings, allowing just two hits, both singles in the second inning when a sacrifice fly by Javier Báez scored the only run.

One of those hits was an infield hit with a head-
