Cardinals general manager John Mozeliak told KMOX on Sunday that right-hander Jake Westbrook has been placed on the 15-day disabled list with right elbow inflammation and that prospect John Gast will be called up from Triple-A Memphis on Tuesday to start in Westbrook’s place against the Mets.
Westbrook presumably developed the elbow issue in his start Wednesday against the Cubs. It was his worst outing of 2013, as he lasted a season-low 5 1/3 innings and allowed four runs (three earned) on nine hits. The 35-year-old was given a cortisone shot Sunday morning and will try to throw later this week.
Gast, a 24-year-old left-hander, has posted an exceptional 1.16 ERA, 1.06 WHIP and 35/13 K/BB ratio across 38 2/3 innings (seven starts) this season at Triple-A Memphis. He was a sixth-round pick of the Cardinals in the 2010 MLB Amateur Draft out of Florida State University.
A day after throwing an immaculate inning — getting through an inning on three consecutive strikeouts with nine pitches — against the Mariners, Dodgers reliever Zac Rosscup was placed on the 10-day disabled list with a left calf strain. The move made room on the 25-man roster for Kenley Jansen, who is back after missing some time due to an irregular heartbeat.
Rosscup pitched the ninth inning of Sunday’s 12-1 win over the Mariners. He struck out Kyle Seager, Ryon Healy, and Cameron Maybin on three pitches each. Rosscup is the fourth pitcher to throw an immaculate inning this season, joining Kevin Gausman, Max Scherzer, and German Marquez. 2018’s four immaculate innings is still far behind 2017’s record of eight.
Rosscup has pitched only 6 2/3 innings in the majors this year. He has yielded five runs (all earned) on seven hits and a walk with 10 strikeouts. He missed a significant amount of time earlier this season due to a blister on his left middle finger.
