Weathers (finger) is expected to be activated from the 60-day injured list to start Wednesday's game against the Dodgers, Isaac Azout of FishOnFirst.com reports.

In his third rehab appearances this past Friday, Weathers worked five scoreless innings for Triple-A Jacksonville, giving up two hits and walking three while striking out eight batters in the outing. After waiting a few days to see how he bounced back, the Marlins have determined that Weathers is ready to return from the IL. He'll face a tough challenge in his first big-league action since June 7, though he kept his team in the game in a matchup with the Dodgers back on May 8, giving up three runs over six innings.

The Angels announced Monday that Dana has been optioned to Double-A Rocket City and won't pitch for the rest of the season in an effort to ensure he enters the offseason at full health, MLB.com reports.

Dana has been hit hard since being promoted at the beginning of the month, surrendering 11 earned runs on 14 hits and seven walks while registering eight strikeouts over 10.1 innings. While this isn't the type of performance he was looking for in his first taste of the big leagues, Dana was the second-youngest player in the majors (behind the Brewers' Jackson Chourio) before his demotion and could win a big-league rotation spot in the spring.

Dodgers manager Dave Roberts said Monday that Yamamoto will not pitch on four days' rest for the rest of the regular season and postseason, Alden Gonzalez of ESPN.com reports.

Four days is considered "normal" rest, but Yamamoto has had at least five days off in between all 15 of his starts this season, a schedule which mimics what he was used to when he pitched in Japan. Even amidst their numerous rotation injuries, the Dodgers are not willing to alter the plan for the rookie right-hander down the stretch. Assuming Yamamoto sticks to a five-day rest schedule, he'll still line up for two starts this week. After he takes the hill Monday in Atlanta, Yamamoto would be on track to make his next start Sunday versus the Rockies at Dodger Stadium.

Walker will draw the start for the Phillies' series opener against the Mets on Thursday, Todd Zolecki of MLB.com reports.

Walker was relegated to the bullpen following his last start against the Astros on Aug. 28, when he allowed six runs on 13 hits and one walk over six innings. He allowed five runs (four earned) across his first two relief outings, but after Walker tossed three scoreless innings against the Mets on Saturday, manager Rob Thompson has decided to give the 32-year-old right-hander another look as the club's No. 5 starter. Overall, Walker holds a 6.29 ERA, 1.63 WHIP and 55:31 K:BB across 78.2 innings this season.

Williams (elbow) is on track to return from the 60-day injured list this weekend versus the Cubs, Mark Zuckerman of MASNSports.com reports.

Williams allowed two runs over 7.1 innings in two rehab starts with Double-A Harrisburg, throwing 73 pitches in his most recent outing Sunday. He should be lined up to start Friday in Chicago, although the exact date for his return hasn't been revealed yet. Williams has been sidelined since late May with a right flexor strain. He had collected a 2.22 ERA, 1.08 WHIP and 47:16 K:BB through 56.2 innings before getting injured.

The Tigers activated Olson (shoulder) from the 15-day injured list Monday, Chris McCosky of The Detroit News reports.

Olson is set to rejoin the rotation Monday versus the Royals after missing nearly two months with a right shoulder strain. The right-hander went just three innings and threw 45 pitches in his last rehab start, so he will be pretty limited Monday from a workload perspective.

The Rockies activated Senzatela (elbow) from the 60-day injured list ahead of his scheduled start Monday versus the Diamondbacks at Coors Field.

Senzatela has completed the long road back from Tommy John surgery, which he underwent last July. The veteran right-hander maxed out at four innings and 68 pitches over his five rehab starts prior to being activated, and the Rockies are likely to keep a close eye on his workload in the final two weeks of the season.

The White Sox recalled Bush from Triple-A Charlotte on Saturday and placed him on the 15-day injured list with a left tricep strain, Scott Merkin of MLB.com reports.

Chicago optioned Bush to Triple-A on Aug. 26, and despite making a one-inning start for Charlotte on Sept. 7, he'll revert to the big club's 15-day IL after suffering the injury in that outing. Given the timing of the injury, Bush is unlikely to be activated before the season ends Sept. 29. Bush made four starts for the White Sox prior to his demotion in late August, logging a 5.60 ERA and 2.04 WHIP while walking more batters (16) than he struck out (11) over 17.2 innings.

Giants manager Bob Melvin said Wednesday that Harrison (shoulder) is unlikely to be activated from the 15-day injured list before the season ends Sept. 29, MLB.com reports.

Though the left shoulder inflammation that sent Harrison to the IL on Sept. 6 has been deemed mild following an MRI, the young southpaw won't be asked to ramp back up with little time left in the season. Harrison had already logged a career-high 124.1 innings prior to being deactivated, which is likely a factor in the organization's decision to shut him down. Over his 24 starts this season, Harrison went 7-7 with a 4.56 ERA, 1.34 WHIP and 118:42 K:BB.

Ray (hamstring) threw another bullpen session Saturday and remains hopeful to return from the 15-day injured list to make one start before the end of the season, MLB.com reports.

Ray faced live hitters in batting practice this past Wednesday, but the session was cut short after 42 pitches when he began experiencing fatigue. The southpaw appears to have avoided a major setback, however, given that he was back on the mound just a few days later. Ray will likely still need to face live hitters on at least one more occasion before the Giants feel comfortable bringing him back from the IL, and he could be on a limited pitch count if he reaches his goal of making one more start for the big club. Landen Roupp should make at least one more turn through the rotation as the Giants' fifth starter until Ray is ready for activation.
