Arrighetti (elbow) said Saturday that he will miss the remainder of the regular season, but his UCL is intact, and he won't require surgery, Brian McTaggart of MLB.com reports.

Arrighetti is dealing with right elbow inflammation, and he hopes to resume throwing once the swelling subsides. The diagnosis comes as good news for the right-hander, who landed on the 15-day injured listed earlier this week. Both Arrighetti and the Astros remain hopeful he can return to the mound at some point in the postseason should Houston make the playoffs.

Kremer underwent an MRI on his right forearm Saturday and will meet with team doctors to determine if he'll need to be placed on the 15-day injured list, Jake Rill of MLB.com reports.

Kremer was removed from Friday's start against the Dodgers after tossing three no-hit innings. If Kremer needs to head to the injured list, interim manager Tony Mansolino said Chayce McDermott will be activated from the taxi squad.

Cobb will undergo hip resurfacing surgery and miss the remainder of the season, Cody Stavenhagen of The Athletic reports.

Cobb had yet to pitch in the majors this season but was trying to work his way back, as he made 10 rehab appearances (seven starts) and recorded a 1.74 ERA, 1.26 WHIP and 24:15 K:BB across 20.2 innings in the minors. Cobb was pulled off his rehab assignment last week but resumed it earlier this week. However, he still doesn't feel right and will go under the knife. The soon-to-be 38-year-old (in October) admitted this could be the end for him in his playing career.

The Tigers activated Paddack from the bereavement list Saturday, Chris McCosky of The Detroit News reports.

Paddack was away from the team the previous three days but will rejoin the Tigers' bullpen for the final two games of the team's series against the White Sox. Paddack has been roughed up across seven appearances (six starts) with Detroit since he was acquired from Minnesota, registering a 6.89 ERA, 1.40 WHIP and 15:5 K:BB across 31.1 innings. He's surrendered 10 home runs in that span.

Scherzer (back) is now slated to start Sunday's series finale against the Yankees in The Bronx, Rob Longley of the Toronto Sun reports.

Scherzer contended with upper-back tightness during his most recent start last Sunday against the Brewers, but since he reported improvement afterward and was able to go through his between-starts routine, the right-hander was initially penciled in to start Saturday's contest versus the Yankees. Though Scherzer hasn't suffered any setbacks, manager John Schneider said he made the decision to push the 41-year-old back an extra day in order to give him more time to recover from the injury. Scherzer isn't expected to be operating with any restrictions during Sunday's outing.

Schlittler (2-3) took the loss Friday as the Yankees fell 7-1 to the Blue Jays, coughing up four runs on five hits and two walks over 1.2 innings. He struck out two.

The rookie right-hander struck out the first two batters he faced on the night, but a Vladimir Guerrero single kicked off a three-run rally in the first inning, and Schlittler eventually got the hook after laboring through 66 pitches (46 strikes). It's the first time he's allowed more than three runs in a start since he joined the big-league rotation in early July, but if there was a silver lining to the stumble, it's that Schlittler still kept the ball in the yard -- he hasn't served up a home run in five straight starts, and through his first 50 MLB innings he sports a 3.24 ERA, 1.34 WHIP, 56:22 K:BB and 1.1 HR/9. He'll look to rebound in his next trip to the mound, which is scheduled to come at home next week against the Tigers.

Gausman (9-10) picked up the win Friday, allowing one run on four hits and one walk over eight innings in a 7-1 victory over the Yankees. He struck out five.

A solo shot by Giancarlo Stanton in the second inning was the only blemish on Gausman's line as he fired 105 pitches (68 strikes) en route to his 14th quality start of the season. The veteran righty has given up two runs or fewer in five of his last six outings, posting a 2.48 ERA, 0.82 WHIP and 35:7 K:BB through 40 innings over that stretch to help lead the Blue Jays' playoff push. Gausman lines up to make his next start at home next week against the Astros.

Kremer left Friday's start against the Dodgers after three innings due to forearm discomfort, Matt Weyrich of The Baltimore Sun reports. The right-hander had struck out four and walked one over three scoreless, no-hit innings before exiting.

The Orioles went on to win the game on a walk-off homer by Samuel Basallo, but Kremer's injury overshadowed the rookie's heroics. Per Jake Rill of MLB.com, interim manager Tony Mansolino indicated after the game that Kremer believes the issue is a minor one, but the team will have a better idea whether he'll be able to make his next start after getting imaging done Saturday. Kremer had coughed up 14 runs (13 earned) in eight innings over his prior two outings, so he may have been attempting to pitch through the discomfort since late August.

Gordon took a no-decision Friday against the Rangers, allowing three runs on five hits and two walks in 4.1 innings. He struck out two.

Gordon continues to struggle in the major leagues, as he's now without a quality start since June 13 against the Twins. That outing was also the last time he pitched at least six frames, and he's yielded at least four runs in five of his last eight outings. Gordon has a poor 5.67 ERA and 1.52 WHIP over 73 innings this season, and he doesn't set up favorably in his next scheduled turn against Atlanta, if he even stays in the rotation.

Kelly took a no-decision Friday against the Astros, allowing one run on five hits and one walk in seven innings. He struck out seven.

Kelly continues to provide the Rangers with plenty of length, having now tossed at least six innings in five consecutive starts. The veteran right-hander is simultaneously riding a streak of five straight quality starts, posting a 2.23 ERA, 0.87 WHIP and 25:4 K:BB during that period. Kelly sports a strong 2.98 ERA, 0.99 WHIP and 35:9 K:BB over 42.1 innings since joining the Rangers, and he's next slated for a difficult task against a Brewers team with an .823 OPS since the beginning of August.
