ARLINGTON, Texas. -

J.D. Martinez has presented manager Brad Ausmus with the best kind of dilemma as the Detroit Tigers aim for their sixth straight win Tuesday against the host Texas Rangers. Outfielder Torii Hunter is expected to return after missing seven games with a strained hamstring, forcing Ausmus to juggle four outfielders, including Martinez, Rajai Davis and Austin Jackson. Martinez will be hard to sit against the slumping Rangers after batting .412 with five homers and 15 RBIs during his 13-game hitting streak.

Texas has lost a season-high six straight games and fallen six games under .500 for the first time since Sept. 23, 2008. The Rangers, who have been held to a total of 16 runs during their losing streak, attempted to spark their struggling offense Tuesday by promoting first baseman Carlos Pena from Triple-A Round Rock. The 36-year-old Pena, who made his major league debut with the Rangers in 2001, batted .207 in 89 games last season with Houston and Kansas City.
