Eflin (knee) threw a bullpen session Saturday, Marc Topkin of the Tampa Bay Times reports.

EDGE Analysis

The Rays wanted to test Eflin's left knee by having him throw off a mound after he tweaked the knee Wednesday versus the Marlins, and manager Kevin Cash said Eflin's session went well and the right-hander is "doing better." However, it remains unclear whether Eflin will be able to make his next scheduled start Tuesday against the Yankees.
