Royals purchased the contract of RHP Kyle Zimmer from Double-A Northwest Arkansas.
By adding the top prospect to the 40-man roster, he is now protected from next month's Rule 5 draft. The 24-year-old posted a terrific 2.39 ERA, 1.14 WHIP and 72/20 K/BB ratio over 64 innings between Class-A Lexington and Double-A Northwest Arkansas in 2015. It's not out of the question to think that Zimmer could debut with the Royals during the 2016 season. Nov 20 - 9:45 PM

Royals prospect RHP Kyle Zimmer has been promoted to Double-A Northwest Arkansas.

Zimmer’s season didn’t begin until late May as a result of setbacks in his recovery from a shoulder injury. However, the 22-year-old right-hander has been sharp over the last month while working out of the bullpen for Low-A Lexington, posting a 1.13 ERA, 1.06 WHIP and 21/6 strikeout-to-walk ratio in 16 innings (nine appearances). He’ll now return to the Texas League, where he made four outstanding starts (18 2/3 IP, 1.93 ERA, 27/5 K/BB) at the end of the 2013 season. Zimmer has struggled to stay healthy during his career, but the 2012 first-rounder's upside is still huge.

Royals prospect RHP Kyle Zimmer struck out three batters over two scoreless innings on Monday for Low-A Lexington.

Zimmer has been working out of the bullpen at Lexington since coming off the disabled list in late May, and he’s now logged multiple innings in three of five appearances. The 23-year-old has yielded just one earned run (0.93 ERA) on seven hits in 9 2/3 innings in that span to go along with a 12/2 strikeout-to-walk ratio. Zimmer is still viewed as one of top pitching prospects in the minors despite logging just 4 2/3 innings last season and dealing with a litany of injuries. His best season came back in 2013 when he posted a 4.32 ERA, 1.17 WHIP, .224 opponents’ batting average and 140/36 strikeout-to-walk ratio in 108 1/3 innings (22 starts) between High-A Wilmington and Double-A Northwest Arkansas. Don’t be surprised if the Royals find a way to use him in the big leagues later this season.

Royals prospect RHP Kyle Zimmer had another successful outing Thursday, allowing one earned run on four hits in three innings for Low-A Lexington.

He struck out three batters in the outing without issuing a walk. Zimmer has been excellent since coming off the disabled list (shoulder soreness) in late May, pitching to a 1.17 ERA with nine strikeouts in 7 2/3 innings (four appearances). A series of injuries limited the 23-year-old right-hander to just 4 2/3 innings last season, which is why the Royals are having him to build up arm strength in the low minors before sending him on a more challenging assignment. Zimmer remains one of the better pitching prospects in baseball despite his concerning medical history, and he potentially could give the Royals a boost later this season, either as a starter or reliever, provided he can stay healthy.

Royals pitching prospect Kyle Zimmer (shoulder) will make his season debut at Low-A Lexington on Friday.

Zimmer had been shut down for a few weeks after having soreness in his surgically repaired right shoulder, but he's back on track now. He'll work in relief for now as the Royals build him up. The 23-year-old was one of the best pitching prospects in the game before the shoulder issues cropped up in 2014, but he's playing catch-up now after throwing just 4 2/3 frames since the beginning of last season.
May 29 - 11:03 AM

Royals prospect RHP Kyle Zimmer has had his throwing program suspended after experiencing soreness in his surgically repaired right shoulder.

He had been pitching at the Royals’ complex in Arizona and was expected to join Double-A Northwest Arkansas on May 10. That clearly won’t be happening, but follow-up examinations revealed no structural damage, and the hope is that Zimmer will resume throwing bullpen sessions sometime next week. The 23-year-old right-hander has been plagued by injuries since the Royals made him the No. 5 pick in the 2012 draft, logging just 152 2/3 innings over three seasons. Zimmer has proved to be dominant when healthy, though, with a 3.66 ERA, .236 opponents’ batting average and 11.0 K/9 in that span.
May 7 - 3:32 PM

Royals prospect Kyle Zimmer (shoulder) is expected to begin throwing in minor league games by May 10.

Zimmer barely pitched in 2014 and underwent a debridement procedure last October 28 to repair his right labrum and rotator cuff. He was ranked the No. 23 prospect in the sport by Baseball America prior to the 2014 season, but lingering arm issues have sunk his stock. He needs a productive 2015.
Apr 6 - 1:47 PM

Royals prospect Kyle Zimmer (shoulder) is scheduled to throw his first bullpen session of the spring on Sunday.

Zimmer is hoping to be pitching in games by May. The 23-year-old right-hander totaled just 4 2/3 innings last season at rookie-level Idaho Falls due to lat and shoulder troubles. He underwent a debridement procedure on October 28 to repair his right labrum and rotator cuff. Zimmer remains a promising young talent, but some things need to start going right on the health side of things.
Feb 24 - 4:34 PM

Andy McCullough of the Kansas City Star reported that the Royals expect Kyle Zimmer (shoulder) to be able to continue with his throwing program this week.

Zimmer was rated as the No. 23 prospect in baseball by Baseball America prior to the 2014 season, but a variety of arm and shoulder injuries have limited him. He pitched just four and two-thirds innings in rookie ball at Idaho Falls before being shut down. On October 28, he underwent a surgical procedure to repair his right labrum and rotator cuff. He was scheduled for a follow-up look at the shoulder on Monday and assuming it's clean, the Royals expect him to be able to resume a throwing program. If Zimmer is able to build up his strength, the 23-year-old could see minor league action by mid-April.
Jan 19 - 2:13 PM

Royals pitching prospect Kyle Zimmer underwent a debridement procedure Tuesday to repair his right labrum and rotator cuff.

The Royals overall were encouraged by how Zimmer's MRIs looked, but they determined that minor surgery was still necessary. The plan is for him to be built up slowly in extended spring training before hopefully returning to game action in late April. Zimmer missed most of the 2014 campaign with shoulder issues and suffered a setback in the Arizona Fall League.

MRIs on Royals pitching prospect Kyle Zimmer's right shoulder came back clean.

ESPN's Jerry Crasnick reported earlier Monday that Zimmer was likely headed for shoulder surgery. He may still get operated on, but it would just be a minor arthroscopic procedure. While any kind of surgery is never optimal, it's the best news the Royals could have hoped for. Zimmer missed a large chunk of the 2014 season due to shoulder issues and it began bothering him again last week in the Arizona Fall League.

Kyle Zimmer will likely need shoulder surgery.

Zimmer missed a large majority of the 2014 season due to a right shoulder injury and it began bothering him again last week in the Arizona Fall League. He is scheduled to visit with Dr. David Altchek this week for an official diagnosis. Zimmer was the fifth overall pick in the 2012 MLB Amateur Draft.

Royals prospect Kyle Zimmer is headed home from the Arizona Fall League and in line for a consultation with Dr. David Altchek regarding his injured right shoulder.

It is believed to be a recurrence of the same shoulder injury that sidelined the right-hander for most of the 2014 season. While it could be a purely precautionary visit, the fact that he continues to have problems in the same area is a troubling sign, and surgery could be on the horizon.

Royals prospect right-hander Kyle Zimmer reinjured his right shoulder Saturday while pitching for Peoria Javelinas in the Arizona Fall League.

Zimmer struck out 11 batters over five innings in his second AFL start, but he was forced to exit after just one inning on Saturday. The fear is that it's the same injury which limited Zimmer to 4 2/3 innings this season in the minors. The Royals will play it safe and shut him down for the rest of the fall. "More than likely, we're not going to push it any further this fall and just try to get this under control," said Royals assistant general manager J.J. Picollo.

Royals prospect RHP Kyle Zimmer allowed one hit and one walk and worked 1/3 of an inning on Sunday in his season debut with Rookie-level Idaho Falls.

The outing was the first time Zimmer has pitched in a game this season, as he only began throwing last month after experiencing a setback in May with his recovery from a lat strain. Prior to the injury, the 22-year-old right-hander had been sidelined for the first six weeks of the season with shoulder inflammation. In 2013, Zimmer registered a disappointing 4.32 ERA in 108 1/3 innings between High-A Wilmington and Double-A Northwest Arkansas, but he still managed to hold opposing batters to a .224 average while striking out 140 batters during that span. He was flat-out dominant over his final eight starts, with a 1.85 ERA, .163 BAA and 63-9 strikeout-to-walk ratio in 43 2/3 innings. If all goes as planned with his rehab work, Zimmer should be ready to make up for the lost time in the Arizona Fall League.
