Analysis: Jacob was optioned to Triple-A El Paso in late September, though that came after the minor-league season had concluded. The righty reliever spent most of the campaign with El Paso but logged seven appearances over two stints with San Diego, posting a 2.45 ERA, 0.75 WHIP and 19:2 K:BB over 14.2 innings. Jacob pitched more than one inning in five of the seven outings and topped out at 3.2 frames against Tampa Bay on Aug. 31.

Analysis: Since returning to the majors at the end of August, Jacob has allowed three earned runs over 8.1 innings across three appearances, though he hasn't pitched in a game since Sept. 14. He'll now head back to the minors as the Padres sacrifice some of their bullpen depth to bring back Randy Vasquez, who will start Saturday's game against the Diamondbacks.
