Go began serving a 10-game suspension at Triple-A St. Paul on July 25 after he was ejected from his appearance against Columbus a day earlier when an illegal substance was found in his glove, Bobby Nightengale of The Minnesota Star Tribune reports.

The 28-year-old right-hander was making his debut for St. Paul after the Twins optioned him to the Triple-A affiliate. Go, who retains a spot on the Twins' 40-man roster, allowed four earned runs on eight hits and two walks while striking out five over four innings in four appearances for the big club prior to his demotion. He'll be eligible to return to action for St. Paul on Thursday.

Zeferjahn allowed two hits and struck out four without walking a batter over 1.2 scoreless innings to earn the save in Sunday's 3-0 win over the Brewers.

Zeferjahn came in during the eighth inning after Sam Bachman (arm) was lifted due to fatigue. While it wasn't quick and tidy from there, Zeferjahn threw 24 of 30 pitches for strikes and worked around a pair of singles to preserve the lead. He's given up three runs, nine hits, two walks and two hit batsmen while striking out 21 over his last 12.1 innings, adding two saves and three holds in that span. Zeferjahn is at a 3.66 ERA, 1.20 WHIP and 75:32 K:BB through 51.2 innings this season. He has held onto a high-leverage spot for most of the campaign, collecting four saves and nine holds for the worst team in the majors.

Bachman is dealing with right arm fatigue, Jack Janes of TheSportingTribune.com reports.

Bachman entered Sunday's 3-0 win over Milwaukee in the top of the eighth inning, recording one out while walking a batter before he was removed from the contest. Bachman threw nine total pitches before his departure, and manager Kurt Suzuki explained after the game that the right-handed pitcher is dealing with some "dead arm." Bachman is expected to be further evaluated, and it's currently unclear if he'll need to undergo an MRI.

The Mariners recalled Simpson from Triple-A Tacoma ahead of Sunday's game against the Twins.

Simpson has appeared in four games out of the Seattle bullpen this season, giving up three earned runs on four hits and two walks across three innings. He'll likely be in store for an abbreviated stay with the big club, as the Mariners will need to clear room on the 26-man active roster for the newly acquired Seranthony Dominguez prior to Tuesday's series opener with the Tigers.

The Tigers recalled Hanifee from Triple-A Toledo on Sunday.

The right-hander will fill the roster spot vacated by Tarik Skubal, whose trade to the Dodgers was made official Sunday. Hanifee has been a solid relief option for Detroit this season with a 3.98 ERA and 1.33 WHIP over 20.1 innings, though he's surrendered nine home runs and struck out just eight batters.

The White Sox optioned Davitt to Triple-A Charlotte after Sunday's 9-1 win over the Rays.

Davitt was called up ahead of Sunday's contest and tossed an inning of relief, allowing one run on two hits while striking out one. The right-hander is expected to be replaced on the 26-man active roster by the newly acquired Luis Castillo, who is expected to make his White Sox debut during the team's upcoming series versus the Red Sox.

The Twins optioned Anderson to Triple-A St. Paul on Sunday.

The 26-year-old's demotion will free up space on the big-league roster for trade-acquisition Dean Kremer. Anderson has made seven appearances in the majors between Boston and Minnesota this season and has a 2.19 ERA, 1.05 WHIP and 12:3 K:BB over 12.1 innings.

The Royals selected Bummer's contract from Triple-A Omaha on Sunday.

The left-hander joined Kansas City on a minor-league deal July 20 and will get a look in the majors after delivering four scoreless outings for Omaha. Bummer made 19 appearances for Atlanta earlier this year and surrendered 13 earned runs with a 13:10 K:BB over 15.1 innings.

The White Sox recalled Davitt from Triple-A Charlotte on Sunday.

The right-hander was up for his first taste of the majors in April and was sent back to Charlotte after firing a scoreless frame in his big-league debut. Davitt will now get another look in the majors despite having a 6.22 ERA, 1.49 WHIP and 64:25 K:BB across 59.1 Triple-A innings It'll likely be a short stay on the 26-man active roster since trade-acquisition Luis Castillo should officially join the team soon.

The Guardians optioned Dion to Triple-A Columbus on Sunday.

The left-hander spent most of June and July in the big leagues but has been shuttled between Triple-A and the majors a few times since the All-Star break. In his first taste of MLB this season, Dion has a 4.58 ERA, 1.37 WHIP and 25:3 K:BB across 19.2 innings. Trade acquisition Craig Yoho will fill the vacated roster spot for Cleveland.
