Paez cleared waivers Saturday and was returned to the Red Sox, Chris Henrique of BostonSportsJournal.com reports. The White Sox selected Paez during the Rule 5 Draft, but he was DFA'd by the club after giving up six earned runs on four hits and three walks in just three innings. The 22-year-old had never pitched an inning above the High-A level before debuting for Chicago, so the Red Sox may send him back down to High-A or Double-A now that he's back in the organization.
The White Sox designated Paez for assignment Wednesday. Chicago will replace Paez on the 40-man roster and in the bullpen with right-hander Lucas Sims, who was called up from Triple-A Charlotte. Since Paez was a Rule 5 Draft selection over the winter, the White Sox will have to offer him back to the Red Sox if he goes unclaimed off waivers. The 22-year-old righty made relief appearances in three of the White Sox's first five games, allowing six earned runs on four hits and three walks while striking out two batters over three innings.
Paez will be included on the White Sox's Opening Day roster, Ari Alexander of 7 News Boston reports. Paez joined the White Sox via the Rule 5 Draft, and although he posted a 6.35 ERA in the Cactus League and has never pitched an inning above High-A, he will break camp with the big club. The 22-year-old right-hander has worked primarily as a starter in the minors but will most likely take on a long-relief role with the South Siders. He will need to remain on the active roster all season or else be offered back to the Red Sox.
