Edwin Jackson has been demoted back to the bullpen.
Jackson gave up five runs in just 2/3 of an inning Friday against the Dodgers, so the Cubs are abandoning the experiment. He has a 6.38 ERA and 1.65 WHIP in 139 2/3 total innings this season for the Cubs.
Jurickson Profar will be shut down 2-3 months with renewed soreness in his right shoulder.
There's no surgery planned yet for Profar, who missed the entire 2014 season due to a torn muscle in his right shoulder. He's experienced multiple setbacks in his rehab and will likely remain a question mark heading into spring training in 2015. Profar turns 22 years old next February.
Rangers activated OF Jim Adduci from the 15-day disabled list.
Adduci missed four weeks with a concussion. He'll be available off the Rangers' bench Tuesday night.
Daniel Norris will make a spot start for the Blue Jays on Thursday versus the Mariners.
It would have been Marcus Stroman's spot, but he's going to pitch out of the bullpen when he returns from suspension. Norris, 21, has allowed two earned runs on four hits and three walks in 3 1/3 innings this month out of the Toronto bullpen.
Marcus Stroman won't make another start this year.
Stroman is going to pitch out of the bullpen when he returns from suspension later this week. The 23-year-old right-hander owns a promising 11-6 record, 3.77 ERA, 1.20 WHIP, and 107/28 K/BB ratio in his first 126 2/3 major league innings. He should be a big weapon for the Toronto starting rotation in 2015 and beyond.
