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.

Montgomery is slated to start Tuesday's game against the Rockies at Coors Field, Jesse Friedman of GoPHNX.com reports.

As expected, Montgomery will return to the Arizona rotation as a replacement for the injured Ryne Nelson (shoulder) following a three-week stint in the bullpen. Montgomery shifted to a relief role after producing a 6.44 ERA over his 19 starts this season, and he didn't fare much better over his four appearances out of the bullpen (4.85 ERA, 1.38 WHIP and 6:4 K:BB in 13 innings). The southpaw covered three-plus innings in three of those relief outings, so he at least should be relatively stretched out as he re-enters the rotation Tuesday.

The Twins claimed Irvin off waivers from the Orioles on Monday, Dan Hayes of The Athletic reports.

Irvin remained in the Baltimore organization after being designated for assignment back in late July, but he did not pass through waivers this time around. The left-hander offers the Twins the versatility to be used as a starter or reliever, but he'll probably be bound for the bullpen after having not started a game since August. Irvin will officially join the Twins' 28-man active roster Tuesday.

Lorenzen (hamstring) struck out four and allowed one earned run on two hits and two walks over 3.1 innings in his rehab start Friday with Triple-A Omaha.

Lorenzen took the hill for Omaha on two days' rest after opening his rehab assignment with a 1.2-inning appearance for Double-A Northwest Arkansas on Tuesday. According to MLB.com, Royals manager Matt Quatraro said Sunday that Lorenzen felt more soreness than usual in his most recent rehab outing, so he'll be re-examined in Kansas City this week before the club determines his next step. Alec Marsh has been filling in as the Royals' No. 5 starter while Lorenzen has been on the shelf with a left hamstring strain.
