Lopez will not make Detroit's Opening Day roster, Evan Petzold of the Detroit Free Press reports.
Lopez is in camp with the Tigers on a minor-league deal, and he's collected five hits in only six at-bats in Grapefruit League action. Despite the impressive small-sample showing, Lopez is in line to start the season at Triple-A Toledo. The 29-year-old made his major-league debut last season with Boston, and he went 2-for-13.
