July 29: RHP John Schreiber (right knee patella tendon injury) placed on 15-day IL; RHP Will Klein recalled from Triple-A Omaha
Schreiber got out of the sixth inning Sunday against the Cubs by throwing one pitch and recording the final out at first base, but he wasn’t able to go back out to pitch the seventh because he felt something in his knee while covering the base. Further scans showed the injury was serious enough to necessitate an IL stint.

The Royals swung a trade with the Rangers on Monday morning to add righty Michael Lorenzen to their pitching staff, but because Lorenzen will not report for at least the next couple of days as he moves his family and belongings to Kansas City, the Royals called up Klein. Lorenzen was likely not going to be able to pitch for the next few days anyway after starting Saturday’s game for the Rangers (and not making it out of the first inning) and pitching four innings in relief Sunday, so Klein gives the Royals a fresh arm in the bullpen. This is the rookie’s third stint with Kansas City this year. He has a 3.58 ERA in Omaha this season.

Reliever Hunter Harvey, who exited Sunday’s game with a left lower back spasm, remains day to day. He said he felt much better Monday, with his back loosened up, and played catch on the field pregame. Manager Matt Quatraro will try to stay away from using him in Monday’s game, but the hope is Harvey would be ready to go Tuesday.

July 29: RHP Michael Lorenzen acquired from Rangers for LHP Walter Pennington
In an effort to increase their pitching depth and versatility on the staff, the Royals acquired righty pitcher Michael Lorenzen from the Rangers on Monday, a day ahead of Tuesday’s 5 p.m. CT Trade Deadline, in exchange for lefty reliever Walter Pennington. Lorenzen, 32, is 5-6 with a 3.81 ERA in 19 appearances (18 starts) with the Rangers this season after signing a one-year, $4.5 million contract during Spring Training, making his season debut on April 15.

General manager J.J. Picollo said Lorenzen could fit any role as the Royals juggle both injuries in the bullpen and starters reaching new territory when it comes to innings pitched. More >>

10-DAY/15-DAY INJURED LIST

RHP John Schreiber (right knee patella tendon injury)
Expected return: End of August
Schreiber came in and recorded the third out of an inning on July 28 against the Cubs with only one pitch thrown, but he wasn’t able to return to the mound for the next inning because he felt a tweak in his knee while covering first base. Further imaging done the next day showed inflammation, and Schreiber was placed on the 15-day IL on July 29. Schreiber received an injection to help with the inflammation. How his knee responds to that in the next few days will determine a timeline for his return, but Schreiber could be sidelined for the next three-to-five weeks. (Last updated: July 29)

60-DAY INJURED LIST

RHP Dan Altavilla (right lat strain)
Expected return: August
Altavilla threw an elevated fastball to A’s leadoff hitter Max Schuemann on June 19 and immediately grimaced in pain while grabbing his side. Altavilla exited a few moments later with a trainer, was placed on the 15-day IL on June 20 and was transferred to the 60-day IL on July 5 to make room on the 40-man roster for Walter Pennington.

After Altavilla was placed on the IL with a right oblique strain, manager Matt Quatraro described the injury as a lat strain. Altavilla has been recovering in Arizona and is throwing bullpens and live BPs there with the expectation that he’ll be ready for a return in late August. (Last updated: July 26)

LHP Josh Taylor (left arm/biceps nerve injury)
Expected return: September
Taylor felt soreness when he was warming up for his Cactus League outing on March 17, and was shut down afterward with left biceps soreness. The lefty reliever was diagnosed with a musculocutaneous nerve injury and placed on the 60-day IL in April. Taylor was shut down for a while and did not begin throwing until July. But now he’s throwing up to 75 feet in Arizona and on a normal progression to ramp up back into pitching shape. It will still be a good amount of time before Taylor is ready for a big league return after that long of a layoff, but the Royals hope to get him on the mound by the end of the season. (Last updated: July 26)
