CLEVELAND -- Back tightness had threatened right-hander Jake Westbrook's start against the Blue Jays on Tuesday night at Progressive Field, to the point where the Indians brought one of their top pitching prospects to Cleveland, just in case.

Westbrook reported the tightness to the team medical training staff Monday, and the Indians had right-hander Carlos Carrasco make the trek north on Interstate 71 from Triple-A as a precaution. No official roster move took place.

The 32-year-old Westbrook reported to work early Tuesday and threw in the indoor batting cages to ensure his back could tolerate the activity. Manager Manny Acta said Westbrook turned out fine and was ready for the start against the Jays.

But Acta also noted that it was possible he might have to lean on his bullpen, should Westbrook's back act up.

"That's why it was so important that Mitch Talbot gave us eight innings [Monday night]," Acta said. "Now, our bullpen is rested."

Had Westbrook not been cleared to pitch, the Indians would have turned to Carrasco, one of four players acquired in last summer's Cliff Lee trade with the Phillies. Columbus had an 11:35 a.m. ET game Tuesday, with Carrasco (2-1, 3.49 in five starts) slated to start. The Indians instructed the Clippers to pull Carrasco from that outing, so veteran reliever Mike Gosling got the nod instead.
