Rays manager Kevin Cash said Monday that Siri (hamstring) had a good day doing straight-line running and could be back relatively soon, Marc Topkin of the Tampa Bay Times reports.

Topkin also cautioned that Siri has to do some side-to-side movement and baserunning and then get some at-bats at the Rays' spring training complex in Florida before heading out on a minor-league rehab assignment. The outfielder was placed on the 10-day injured list April 8 with a strained right hamstring and looks like he'll have a chance at returning in the final week of the month if he can avoid any setbacks.
