Padres pitcher Blake Smith has cleared waivers, according to Dennis Lin of U-T San Diego (on Twitter). The Padres will now return the Rule 5 Draft selection to the White Sox.

Smith, 28, was a second round pick of the Dodgers in 2009 The University of California product was in the Los Angeles organization until May 2015 when he was shipped to the White Sox for left-hander Eric Surkamp.

Last year, Smith split time between Double-A (with both Dodgers and White Sox affiliates) and Triple-A, posting a combined 3.23 ERA with 10.9 K/9 and 4.6 BB/9. When he was left exposed, the Padres pounced in the Rule 5 draft. However, he apparently did not do enough to compel the Padres to add him to the big league bullpen.
