Fitts will start Friday against the Twins, Christopher Smith of MassLive.com reports.

Fitts most recently made a spot start Sept. 13 in place of Tanner Houck, who was dealing with shoulder fatigue. Even with Houck back in action, Fitts will get another turn through the rotation. He has yet to allow an earned run across 10.2 innings, though his 4:4 K:BB is less impressive.

Alexander will start Friday's game against the Blue Jays, Marc Topkin of the Tampa Bay Times reports.

Alexander has worked bulk innings for the entire season, though he's fluctuated between working behind an opener and as a traditional starter. Topkin reports there will be no opener Friday, setting Alexander up for his eighth start of the campaign.

Cousins (pectoral) is likely to be out for a few days after exiting his outing Thursday, Bryan Hoch of MLB.com reports.

Cousins was pulled with the issue in the sixth inning. After the game, he said he's been dealing with the injury since Sunday but had progressed to the point where he thought he could pitch in game action. Even with the setback, it appears that Cousins will avoid the injured list.

Cousins was removed from Thursday's game against the Mariners due to right pectoral tightness, Gary Phillips of the New York Daily News reports.

The Yankees' training staff saw something they didn't like after Cousins struck out Julio Rodriguez in the sixth inning, and they made the decision to pull their right-hander after he recorded just one out. The team will take a closer look at Cousins in the clubhouse to determine the severity of his injury, though he may be unavailable out of the bullpen for the next couple of days.

Dominguez was charged with a blown save in Friday's 5-3 win over the Giants, allowing a run on one hit and two walks in one-third of an inning.

Protecting a one-run lead in the ninth, Dominguez walked the first two batters he faced before Casey Schmitt tied the game with a base hit. It's the first blown save in 10 chances for Dominguez since he joined the Orioles in July. The right-hander has allowed three runs in his last two appearances (1.1 innings) after allowing just one run in his previous 7.1 frames. Despite his recent struggles, Dominguez figures to remain in the closing role down the stretch. His ERA sits at 4.37 on the year with a 1.20 WHIP and 66:18 K:BB across 55.2 innings between Baltimore and Philadelphia.

The Red Sox optioned Horn to Triple-A Worcester on Thursday, Christopher Smith of MassLive.com reports.

Just five days after being recalled to the big-league club, Horn will return to Triple-A to make room for Lucas Sims (lat), who was activated from the injured list in a corresponding move. Horn made three appearances during is latest stint in the majors, allowing one run on two hits and three walks across one inning.

The Red Sox activated Sims (lat) from the 15-day injured list Thursday, Christopher Smith of MassLive.com reports.

Sims missed a little more than three weeks of time with a right lat strain but has been cleared to rejoin the Boston bullpen after making a couple rehab appearances with Triple-A Worcester. He's collected an 8.10 ERA in 11 outings for the Red Sox and will likely be pegged for middle relief.

Yankees manager Aaron Boone said Thursday that while Weaver could close out "a lot" of games, the skipper stopped short of naming the right-hander his closer, Erik Boland of Newsday reports.

Boone noted that he wouldn't hesitate to use Weaver earlier in the game if the situation calls for it. Weaver has notched two saves since Clay Holmes was demoted from the closer role and boasts a dominant 16:3 K:BB over 7.1 scoreless innings during that time. However, while Weaver might be the favorite to lead the Yankees in saves down the stretch, it doesn't sound like Boone is eager to have defined roles in the back end of his bullpen.

Snider (3-4) was charged with the extra-inning loss against the Yankees on Wednesday, allowing an unearned run on one hit over two innings. He struck out three.

Snider was a tough-luck loser and victim of the Mariners' offensive ineptitude Wednesday, as he put together a near-perfect outing that saw him throw 17 of 20 pitches for strikes. However, the right-hander faltered in the 10th inning by allowing a leadoff double to Anthony Rizzo, which plated phantom runner Jasson Dominguez to snap a 1-1 tie. Snider has given up just one earned run over his last 9.2 innings (nine appearances), and although he does have four holds to show for it, he's also taken two of his four losses on the season during that stretch.

Ferguson (4-2) got the win against the Cubs on Wednesday, firing a scoreless seventh inning during which he issued a walk.

Ferguson threw only three of his 10 pitches for strikes, but he was able to get through the seventh frame unscathed and then saw the Athletics snap a 3-3 tie in the eighth to make him the pitcher of record. Ferguson has now strung together four consecutive scoreless appearances after a rocky early-September stretch during which he surrendered five runs (four earned) across 3.1 innings over four appearances.
