Chicago Cubs injury report: Wade Miley moves closer to a rehab assignment, but Adbert Alzolay isn’t throwing yet

ATLANTA — The Chicago Cubs will be waiting a little longer for their short-term injured pitchers to join the team.

Left-hander Wade Miley threw 46 pitches Wednesday afternoon, getting in three up-downs during a simulated game at Truist Park. The Cubs want to see how he feels before determining his next steps, but Miley is getting closer to going on a rehab assignment.

The veteran shouldn’t need more than two rehab outings before coming off the injured list. Given his experience and understanding of his body, Miley might need only one rehab start.

Right-hander Alec Mills was slated to make a rehab start Friday for Triple-A Iowa; however, he won’t pitch after feeling tightness in his right quadriceps while working out Tuesday. Mills will get a couple of days off before the Cubs implement his throwing schedule. He could throw another bullpen session before making his next rehab start.

Outfielder Clint Frazier, who went on the IL on April 20 after an appendectomy, is expected to go on a rehab assignment once he has fully healed. An appendectomy typically takes four weeks to come back from for hitters.

Frazier likely would have been optioned to Iowa when big-league rosters reduce from 28 to 26 players Monday. He was one of six outfielders on the Cubs active roster before going on the IL. A rehab stint would give him a chance to get in a rhythm at the plate after starting five of the Cubs’ first 12 games.

The Cubs have four players on the 60-day IL who can’t be activated before June 6.

Infielder David Bote, who is coming back from left shoulder surgery, likely will begin a rehab assignment in mid- to late May if he continues to trend in the right direction. That would put Bote on track to be activated as soon as he is eligible.

There isn’t an obvious spot on the big-league roster for Bote based on the current roster construction. While injuries could change that by the time Bote is full go, he does have a minor-league option the Cubs could use.

Right-hander Adbert Alzolay (right shoulder strain) is working out but not throwing yet. The team hopes Alzolay will begin the ramp-up process soon.

Part of the benefit of being on the 60-day IL is a pitcher coming off an injury like Alzolay’s has ample time to build arm and shoulder strength. Alzolay reported to spring training with the shoulder issue and got a platelet-rich plasma (PRP) injection in early March. If the Cubs bring him back as a reliever, it would shorten the length of his rehab.

Left-hander Brad Wieck (left elbow strain) had a PRP injection in late March and is further behind Alzolay. He isn’t expected to return until the second half of the season.

Right-hander Manuel Rodríguez (right elbow strain) received a PRP shot with the hope of avoiding surgery. The Cubs will know more about Rodríguez’s outlook after he begins a throwing program in a couple of weeks.

Left-hander Steven Brault is on the Triple-A IL after an MRI during his physical in March showed a triceps issue. He is going through a strengthening program for his arm with a return possibly three months away.
