Pirates' Ivan Nova: Sunday start interrupted by hamstring discomfort
by RotoWire Staff | Special to CBSSports.com
(3:46 pm ET) Nova was pulled from Sunday's start against the Brewers after six innings due to left hamstring discomfort.

Nova cruised through six frames, surrendering only one run on three hits and no walks while striking out four batters over an economical 75 pitches. He departed the game with a 2-1 lead, so he'll be in line for the win if the Pirates' relief crew is able to keep the Brewers off the board. The Pirates will provide Nova with treatment over the next few days with the hope of alleviating the pain he's experiencing with the hamstring, but as of now, there's no guarantee he'll be able to make his next start. Look for manager Clint Hurdle to provide clarity on Nova's situation after Sunday's game concludes.


Dodgers' Jose De Leon: September call-up not guaranteed
by RotoWire Staff | Special to CBSSports.com
(3:12 pm ET) Dodgers manager Dave Roberts said Sunday that De Leon would only receive a September call-up if the team has a need for him, David Vassegh of 570 AM LA Sports reports.

Despite several members of the Dodgers' starting pitchers succumbing to injuries this season that has left the rotation in shambles, the organization has resisted the temptation thus far to promote De Leon, one of their top pitching prospects, to the big leagues. De Leon has only covered 78.2 innings at Triple-A Oklahoma City this season and has posted dominant numbers (2.86 ERA, 0.98 WHIP, 98:20 K:BB ratio), so service-time considerations might be the primary reason why the 24-year-old has yet to make his debut.


Athletics' Sonny Gray: Set to begin playing catch soon
by RotoWire Staff | Special to CBSSports.com
(2:40 pm ET) Gray (forearm) is expected to begin playing catch this week, MLB.com's Jane Lee reports.

Gray hit the DL three weeks ago after experiencing inflammation in his right forearm, leading some to believe that the A's might consider shutting him down for the season. While that could still be the case, Gray will at least attempt to rehab the injury with the intention of returning in September, though he'll have to clear several hurdles along the way. Given that Gray has been blasted to the tune of a 5.74 ERA across 116 innings this season, it's probably not beneficial for most fantasy owners to stash him on their rosters until he returns.


Athletics' Henderson Alvarez: Will begin rehab assignment early this week
by RotoWire Staff | Special to CBSSports.com
(2:38 pm ET) Alvarez (shoulder) is set to begin a rehab assignment with High-A Stockton within the next few days, MLB.com's Jane Lee reports.

Alvarez hasn't been able to pitch for the A's all season while he's endured multiple setbacks in his recovery from July 2015 surgery to repair a tear in his throwing shoulder. For the third time this season, Alvarez will attempt to head out on a rehab assignment after his previous two efforts were thwarted, meaning a return to the A's before the conclusion of the campaign is still on the table. The right-hander threw 13 pitches during a simulated outing in Arizona on Saturday, with his fastball checking in around 89-to-91 miles per hour. If he continues to make velocity gains and avoid any further setbacks, Alvarez could serve as a bullpen option for the Athletics later in September.


Rays' Alex Cobb: Expected to make 2016 MLB debut Friday or Saturday
by RotoWire Staff | Special to CBSSports.com
(2:26 pm ET) Cobb (elbow) is expected to be activated from the 60-day DL and make his first start of the season for the Rays either Friday or Saturday against the Blue Jays, MLB.com's Bill Chastain reports

Cobb, who missed all of last season while recovering from Tommy John surgery, concluded his eight-start rehab assignment Saturday, covering four innings and surrendering one run and five hits in an outing for Triple-A Durham. With a 6.65 ERA, 1.80 WHIP and 15:8 K:BB ratio across 21.2 innings with Durham and High-A Charlotte, Cobb didn't exactly look sharp during his rehab, but more important than his results was the fact that he endured no setbacks with his elbow along the way. He'll likely experience plenty of ups and downs in his performance with the Rays over the final month of the season, but with the team out of playoff contention, the main priority will be ensuring that Cobb enters the offseason with his health fully intact heading into 2017.


White Sox's Miguel Gonzalez: Will head out on rehab assignment

(2:04 pm ET) Gonzalez (groin) will head out on a rehab assignment Sunday, MLB.com's Scott Merkin reports.

The White Sox haven't specified which affiliate Gonzalez will join, but the plan is to have him back by next weekend, when rosters will have expanded to 40 men. Once activated from the DL, Gonzalez will likely replace Anthony Ranaudo as the fifth starter in the Sox's rotation.


Dodgers' Julio Urias: Will remain in rotation
by RotoWire Staff | Special to CBSSports.com
(1:50 pm ET) Urias will remain in the Dodgers' rotation, David Vassegh of AM 570 LA Sports reports.

Urias was fantastic during Saturday's outing against the Cubs as he allowed just one run over six innings and struck out eight batters in the process. As a result, his ERA is now 3.71 for the season. The Dodgers have yet to say when his next start will be, although it's likely Urias will return to the mound this week against the Rockies or Padres.


Rockies' Tyler Chatwood: Set to begin rehab assignment
by RotoWire Staff | Special to CBSSports.com
(1:40 pm ET) Chatwood will pitch at Double-A Hartford on Monday, Nick Kosmider of the Denver Post reports.

Fortunately, it appears that Chatwood is on track to come off the DL in the near future. Colorado has yet to say how many rehab starts Chatwood will make, although it's known that he'll be limited to 75 pitches in Monday's outing. More information regarding his eventual return should be known after his upcoming outing.


Brewers' Junior Guerra: Set to return next weekend
by RotoWire Staff | Special to CBSSports.com
(12:40 pm ET) Guerra (elbow) is expected to rejoin Milwaukee during next week's series against the Pirates, Adam McCalvy of MLB.com reports.

As long as Guerra's rehab assignment continues as planned, he'll be activated from the DL between September 2 and 4. Guerra had a solid performance during his first rehab start at Triple-A Colorado Springs as he allowed just one hit and walked two batters over 3.1 innings.


Pirates' Steven Brault: Scheduled to pitch Monday
by RotoWire Staff | Special to CBSSports.com
(12:28 pm ET) Brault is expected to pitch Monday against the Cubs, Stephen J. Nesbitt of the Pittsburgh Post-Gazette reports.

Over 16 games at Triple-A Indianapolis, Brault has posted a 3.91 ERA and 1.42 WHIP. He's had experience with the Pirates this season, as he's thrown 10 innings over two games, allowing four earned runs and striking out eight batters along the way. However, he'll have his work cut out for him Monday against the Cubs, the league's third-highest-scoring offense.
