Padres place former All-Star pitcher on IL

The Padres placed starter Nestor Cortes on the 15-day injured list, retroactive to Sept. 4, with a biceps strain. San Diego recalled reliever Ron Marinaccio to provide an extra bullpen arm for tonight’s game in Colorado. It might be a one-day MLB stint. Righty Randy Vásquez joined the team at Coors Field and told reporters (including Jeff Sanders of The San Diego Union-Tribune) that he’ll be recalled to start Saturday’s game.

It continues a rough season for Cortes, whom the Friars acquired from the Brewers at the trade deadline. The lefty’s Milwaukee tenure consisted of two starts and eight runs allowed in as many innings. He then suffered a flexor strain that cost him four months. By the time he was ready to return right around the deadline, the Brewers had six or seven better starting pitchers. They traded Cortes to San Diego, who activated him from the IL on Aug. 3.

Things haven’t gone well through six starts. Cortes carries a 5.47 earned run average through 26 1/3 innings. His strikeout, walk and home run rates are all poor. Cortes has managed one strong start, tossing six scoreless innings to beat the Dodgers on Aug. 23. That’s the only time he’s completed six frames with the Padres. He had his worst outing on Wednesday, giving up four homers and six runs without escaping the third inning against Baltimore.

San Diego acquired Cortes and JP Sears at the deadline in an effort to stabilize the back of the rotation. That became increasingly important when they packaged Ryan Bergert and Stephen Kolek to Kansas City for catcher Freddy Fermin. Neither addition has worked out so far, as Sears has given up nine earned runs in 14 2/3 frames over his first three starts.

The Padres quickly optioned Sears to Triple-A. He apparently has fallen behind Vásquez on the depth chart, as the Friars elected to call up the righty. Sears is scheduled to start tonight in the minors, which would indicate he’s not in the mix to start on Tuesday in what would have been Cortes’ rotation spot. (San Diego relied on a bullpen game the last time they would have needed a fifth starter.) They may be targeting that day for Michael King to return from the injured list. Manager Mike Shildt told 93.7 The Fan that King threw five innings in a scrimmage at the team’s Arizona complex yesterday. Shildt did not commit to a date for the righty’s reinstatement.
