The Cleveland Indians' phone lines are busy these days.

Not only are there rumblings that rival teams are interested in star shortstop Francisco Lindor, but the Indians are also receiving inquiries about their young starting pitchers, including Shane Bieber, Zach Plesac, and Aaron Civale, according to Jon Heyman of MLB Network.

Cleveland doesn't consider any player untouchable, but it would take a lot to pry any of those young starters away, Heyman added.

Bieber, 24, is fresh off a breakout campaign that saw him start the All-Star Game for the American League team.
