CHICAGO -- The Yankees did not complete a splashy deal in advance of Friday's Trade Deadline, but they still managed to shake up the clubhouse with an exciting move, announcing that they will promote right-hander Luis Severino to make his Major League debut.
Severino will join the rotation next week against the Red Sox, with the date of his debut still to be determined. The 21-year-old is the the organization's No. 1 prospect, according to MLB Pipeline.
"He's earned it, and we need it," Yankees general manager Brian Cashman said. "So we'll see what the next step for this youngster is. He moved really fast through the system and obviously had a lot of success. We'll see what the next level is going to be like for him and hopefully he can contribute and add into the cast of characters. He's somebody we're excited about."
Coming off a career-high 10 strikeouts over six innings of one-hit ball in his last outing on Wednesday for Triple-A Scranton/Wilkes-Barre at Lehigh Valley, Severino has been dominant since his promotion to Triple-A earlier this summer.
Severino was 7-0 with a 1.91 ERA in 11 starts for the RailRiders, posting a .184 average against and a 0.93 WHIP. He will assume a rotation slot vacated by Michael Pineda, who is on the 15-day disabled list with a strained right forearm flexor tendon. Cashman indicated that Severino could receive an extended look.
"We'll see how it all shakes out," Cashman said. "It's all hands on deck from our system."
Since Severino's last start was on Wednesday, the hurler could slot into the rotation as soon as Aug. 4 against the Red Sox at Yankee Stadium. Yankees manager Joe Girardi confirmed that Severino will pitch one of the games against Boston.
"He's got a big arm, he's got a very good changeup," Girardi said. "His slider has developed. What I saw in Spring Training, and I know it wasn't a ton of innings, there was no fear there. There was a guy that went right at hitters with his stuff. I think that's important, that he continues to do that."
Severino has pitched 99 1/3 innings this year, hurling 38 at Double-A and 61 1/3 at Triple-A, after throwing 113 last season. Cashman said that Severino will not have any innings limits imposed upon him once promoted.
"He doesn't have any," Cashman said. "We prepared in the front end of this thing that if we needed him, we needed to make sure that he was available to provide what we needed. So there isn't any inning limit on him. He's good to go."
"I think it just tells you we have depth in our Minor Leagues that we haven't had in a while," Girardi said. "You think about the last time that we relied on a lot of young players, it was a long run. Hopefully that transpires and these kids continue to develop the way that we think they're capable of and make the impact that we think they're capable of."
