Jose Reyes: Reyes is expected to be activated on Friday. He's currently on a rehab assignment at Dunedin (A) and if all goes well, he'll be back for the weekend series. With Adam Lind having back issues, that could make for an easy roster swap.
Mike Napoli: Late Tuesday, Mike Napoli dislocated his finger on a slide. It was an ugly injury—if you want to see it, I'm sure you can Bing up some results—but there was no fracture. Depending on whether there was any associated damage inside, Napoli could still need some DL time. We'll know within the next few days what the Boston Red Sox will do.
Aroldis Chapman: Chapman continues to make progress, getting up on a mound for a 25-pitch bullpen session. He's had no issues and could go out on a quick rehab assignment, likely to Dayton or Louisville, next week. He'll come back quickly to the closer role and could be a bump for a struggling Cincinnati Reds pen.
Adrian Beltre: Beltre wasn't happy about being pushed to the DL for his quad strain, but the Texas Rangers tend to be pretty conservative with injuries like this. Even more so early in the season and when they need to test out their backup infielders. Kevin Kouzmanoff is a nice comeback story, and if Beltre will need more rest this season, he could be a big part of the Rangers' success. Beltre should be back at the minimum and could be used more at DH than in the past.
Michael Bourn: Bourn was activated by the Cleveland Indians, bumping Nyjer Morgan from his role as the speed guy in CF. Bourn is coming off difficult hamstring surgery, so don't expect immediate speed. Any sort of sign that he's lost no range is a plus, and any steals will be a big positive. I'm not saying Bourn can't get his speed back, just not to count on it in the short term.
Alex Cobb: After Matt Moore, the Tampa Bay Rays don't need more pitching injuries. Cobb has a simple oblique strain, but that will cost him a month or more. The Rays tend to be conservative with these types of injuries. Look for Erik Bedard to try to hold down the No. 5 spot, but by definition, this would be a prime opportunity for a four-man rotation.
Colby Lewis: Lewis had a nice first start back after hip and elbow issues. He showed normal velocity and his typical sink, though he struggled at times with consistency on his release point. He puts a lot of pitches in the dirt, which taxes his catchers, but this should adjust some as he gets more comfortable. There's some question about proprioception with the hip, so see if there's any change with 58 foot fastballs in the coming weeks.
Taijuan Walker: The Seattle Mariners were expecting Walker to make one more start at Tacoma and then come up to take James Paxton's spot in the rotation. Problem is, Walker didn't make that start. He showed up with a stiff shoulder and the team is worried it's back at square one with Walker. He's definitely not going to make his next start in Seattle, but we'll have to watch to see how much of a setback this is.
Josh Johnson: Jeff Passan of Yahoo! Sports reports that Johnson is likely headed toward a second Tommy John surgery. An injury-prone pitcher went to the Toronto Blue Jays and San Diego Padres, two teams who have had their difficulties keeping pitchers healthy, and is surprised at this result? His agent needed to guide him toward the Chicago White Sox, Milwaukee Brewers or Rays, assuming they would take a shot on him at this stage. If he has the surgery, he'll get another shot since pitching is so thin and GMs always remember who a guy was.
Juan Lagares: Lagares has hit the DL with a simple hamstring strain, but with Curtis Granderson banged up as well, the team has to shuffle a bit. Kirk Nieuwenhuis will come in, but Chris Young is the more likely long-term replacement once he comes off the DL himself. Lagares is a speed guy, so watch to see how he deals with this injury and if it becomes recurrent.
Avisail Garcia: Garcia not only had his labrum repaired this week, he also had an avulsion fracture inside the shoulder. That means there's pretty extensive damage in the shoulder. While it's not his throwing shoulder, look at how Adrian Gonzalez and Matt Kemp struggled with their swings for at least a while after shoulder surgery. Neither had as serious an injury as Garcia either. He's done for the season, but this development makes it tougher to even think about him as a keeper.
Brett Anderson: Anderson has a strange injury, as he broke his finger on a swing. The X-ray showed enough damage that the Colorado Rockies were forced to DL him, and we'll see how they bring him back. The question will be about stamina, but there are ways to keep his arm going, even with the finger. He may have surgery to speed the healing and stabilize things, but even that might not get him back much faster. When healthy, he's got the best stuff on that staff, but it's a big "if."
