Lowe is out of the lineup for Friday's game against the Orioles with ligament inflammation on both sides of his middle finger, Ryan Bass of Bally Sports Sun reports.
The Rays are trying to get the inflammation to "calm down," per manager Kevin Cash, but right now they're unsure how long it's going to take before Lowe can return to action. The second baseman had his finger wrapped prior to Friday's game and will be sent for further evaluation. Jose Caballero is starting at second base Friday against right-hander Dean Kremer, with Taylor Walls at shortstop.
