As the trade deadline approaches, the belief is that the Tigers need to add a right-handed bat. After homering from the right side for the second straight game in Detroit’s win over the Pirates on Tuesday, switch-hitting Wenceel Perez beamed when asked to gauge his confidence level and said, “Oh my god, it’s so high right now.” Since rejoining the Tigers after missing the first two months of the season with a back injury he suffered late in spring training, Perez has been the best hitter in their lineup. Perez was similarly hot when he arrived last season, before cooling off as the league adjusted to him.
