Each day in March, NBC Sports Chicago is previewing one player from the Cubs’ expected 2020 Opening Day roster. With four bullpen roles still up for grabs, let's pivot to pitcher Adbert Alzolay, who will join the club at some point this season.

2019 recap

Alzolay made his MLB debut last summer as one of the more high-profile pitching prospects during Theo Epstein’s tenure in Chicago. The 25-year-old made four appearances (two starts), delivering an up-and-down performance.

In 12 1/3 innings, Alzolay allowed 10 earned runs on 13 hits and nine walks. A bulk of that damage came in a start on July 1 against the Pittsburgh Pirates when he surrendered seven earned runs on 10 hits in 2 2/3 innings.

Expectations for this season’s role

The Cubs reassigned Alzolay to minor league camp on March 10. He was in the mix for the final rotation spot, but that competition is now down to Tyler Chatwood and Alec Mills.

Alzolay will start the year in Triple-A Iowa’s rotation, which allows him to stretch out and build up arm strength. He missed most of 2018 with a lat strain and the first month of 2019 with another. His career-high for innings is 120 1/3 (2016 in Single-A), so there will be innings limitations for him this season. 

We’ll see Alzolay on the North Side at some point in 2020, likely in a relief role where he can eat up innings and matchup versus righties and lefties. He could make a few spot starts as well.

 

2020 outlook 

Improvement for Alzolay lies in better results from his four-seam fastball. MLB opponents hit .385/.515/.808 against it last season compared to .154/.313/.385 against his curveball and .091/.091/.091 against his changeup. 

Alzolay told the Chicago Tribune’s Mark Gonzales that he sometimes loses feel for his changeup and has been working on it this offseason. His curveball is his go-to out pitch (30.8 putaway percentage last season), but opponents can sit fastball if he isn’t fooling them with the change.

Throwing an effective changeup more frequently will make Alzolay more deceptive and keep hitters off balance. If he finds success with all three of his pitches, David Ross can use him in a variety of roles out of the bullpen, building towards a full-time rotation role in 2021.
