Right-hander Tyson Miller is scheduled to make his major league debut Monday, in the second game of the Cubs’ doubleheader against the Cardinals.
“Tyson’s been throwing really well," Cubs manager David Ross said. "He’s got a couple new toys that he’s developed down there in South Bend, as far as pitch mix.”
The Cubs recalled Miller from the South Bend alternate site as their “29th man” Monday. Teams are allowed to recall an extra player for doubleheaders, per the 2020 operations manual.
The opportunity opened up for the 25-year-old through a series of injuries.
Tyler Chatwood was originally also scheduled to pitch Monday, after missing his start Friday due to mid-back tightness. But that plan changed after the Cubs placed him on the 10-day injured list Sunday (retroactive to Aug. 13) with a mid-back strain.
Adbert Alzolay, another starting pitcher in South Bend, was hit on the right forearm by a comebacker a few days ago, according to Ross. Alzolay pitched in four major-league games last year, two starts and two relief appearances. Ross said he may still be an option to start one of the Cubs’ two games on Wednesday.
The Cubs selected Miller in the fourth round of the 2016 Draft. Lat season, in 26 Double-A and Triple-A starts combined, Miller went 7-8 with a 4.35 ERA.
He joins the big-league roster in a strenuous week for the Cubs. They are scheduled to play five games against the Cardinals in three days, with seven-inning doubleheaders on Monday and Wednesday.
Kyle Hendricks and Miller are penciled in to start on the mound Monday, and Yu Darvish on Tuesday. Right-hander Alec Mills is scheduled to pitch one of the two games Wednesday, but the other starter remains uncertain.
