What the Tigers know, for certain, 10 days before baseball’s Winter Meetings convene at Disney World, are their shopping specifics. Although general manager Al Avila isn’t offering details, a person familiar with their business agenda, and who asked not to be identified, said the Tigers are following these generally acknowledged offseason outlines: They want to sign ahead of 2018’s spring camp two lost-cost starting pitchers. And, perhaps, a reliever. They are looking hard for a left-handed hitting outfielder. They will be waiting Friday to see which players are “non-tendered” by their clubs, the formal term for a team not offering a 2018 contract to a player. This most often happens because of potential salary arbitration costs that a team views as not worthwhile. The Tigers, meanwhile, are burrowing into their minor-league scouting reports in a bid to grab, for a mere $100,000, a player they might poach from another club in the Dec. 14 Rule 5 draft, which traditionally wraps up the Winter Meetings. The Tigers have the first pick in this year’s Rule 5 draft and are almost certain to snatch a pitcher or position player who must be carried next season on their 25-man active roster. Players eligible for the Rule 5 draft have, in most cases, spent four or more seasons in the minors and haven’t been retained on a team’s 40-man roster. One potential pick could be Travis Demeritte, 23, a second baseman and right-handed hitter who couldn’t be squeezed onto a loaded Braves team’s 40-man list. Demeritte has power and would make sense if the Tigers, as anticipated, trade Ian Kinsler, who has been part of conversations between the Tigers and multiple teams.
