A month into the offseason, the Tigers’ hot stove finally has begun to heat up with the addition of veteran left-hander Matt Moore on Tuesday.

Moore, once considered one of the top pitching prospects in baseball and still just 29 years old, will join the Tigers on a one-year deal worth around $2.5 million, according to multiple persons with knowledge of the situation.

The deal will be finalized pending a physical, which is expected to take place in the next week.

Moore, a one-time All-Star, will join the club after struggling the past two seasons, and the Tigers hope he can bounce back to his middle-of-the-rotation form to stabilize the starting rotation and, perhaps, provide a trade return next season.

In eight seasons, Moore has posted a 4.56 ERA and 1.41 WHIP, with 8.1 strikeouts per nine innings. Until the second half of last season with the Texas Rangers, he has been a full-time starting pitcher.

In 2018, Moore struggled to the tune of a 6.79 ERA and 1.65 WHIP, prompting Texas to move him to the bullpen. Some rival talent evaluators believe his best role is pitching out of the bullpen as a swingman, but the Tigers are hoping he claims a rotation spot in spring training.

Moore spent the first six seasons of his career with the Tampa Bay Rays and was an American League All-Star in 2013.

His stuff remains solid — Moore’s fastball has steadied at 93 mph — but his command and lack of consistency have prevented him from ascending as high as many believed he would.

Still, the pending signing is precisely the kind that many expected the Tigers would make this offseason, following their blueprint of last offseason, when they signed righty Mike Fiers and lefty Francisco Liriano to one-year deals.

Fiers was traded to the Athletics for two prospect pitchers in early August. The Tigers were unable to trade Liriano, who became a free agent this offseason.

Moore has less of a track record than Fiers, but more upside. Before his two seasons with the Giants and Rangers, he posted a respectable 3.91 ERA in 108 games.

Perhaps a change of scenery will help Moore recapture his early form, as could escaping a hitter’s ballpark in Texas — Moore had a 7.96 ERA at Globe Life Park last season..

The Tigers, as they continue to rebuild, hope to plug as many holes as possible with players who can up their value in Detroit, then trade them for prospects to boost the farm system.

Given that Moore’s contract is for one year and without an option, the Tigers are almost certainly hoping for the same.

It's unclear whether the Tigers will pursue additional starting-pitching help in free agency this offseason, but the club has seemed open to adding more arms overall.
