The Twins selected Helman's contract from Triple-A St. Paul on Sunday, LaVelle E. Neal III of The Minnesota Star Tribune reports.

Helman will receive his first taste of the big leagues with MLB rosters expanding to 28 players Sunday. The 28-year-old has a .282/.366/.502 slash line with 13 home runs and 10 steals in 63 games with St. Paul this season and will provide the Twins with some infield depth.

Lopez is out of the lineup for Sunday's game against the Mets.

With lefty Sean Manaea on the hill, the lefty-hitting Lopez will retreat to the bench for the series finale. The White Sox recently placed Lopez on waivers, but with the 29-year-old going unclaimed, he appears set to stick around in the organization for the rest of the season. Lopez should continue to play regularly against right-handed pitching.

Baldwin is out of the lineup for Sunday's game against the Mets while tending to a right hand injury, Scott Merkin of MLB.com reports. "Probably take it slow," interim manager Grady Sizemore said in regard to Baldwin's recovery from the injury. "We are going to see how batting practice goes, and I think he's going to have probably just down at least [Sunday and Monday] and see how he's doing Tuesday."

The injury helps explain why Baldwin will be on the bench Sunday for a fifth consecutive game after he had previously handled a near-everyday role in the White Sox middle infield following his call-up from Triple-A Charlotte on July 19. The White Sox should have steady playing time available in the infield for Nicky Lopez, Miguel Vargas and Lenyn Sosa while Baldwin is tending to the injury.

The Royals optioned Loftin to Triple-A Omaha on Sunday.

The 25-year-old was called up by the Royals on Thursday but won't stick in the majors long following the additions of veterans Tommy Pham, Robbie Grossman and Yuli Gurriel. Loftin hasn't done much while up in the big leagues this season and has a .518 OPS in 57 games.

The Red Sox recalled Valdez from Triple-A Worcester on Sunday.

He'll be one of two September call-ups for Boston, with right-handed reliever Chase Shugart also getting moved up from Triple-A. Over his 189 plate appearances at the big-league level this season, Valdez has slashed .224/.282/.400 with six home runs and one stolen base. Though he's not in the lineup for Sunday's game against the Tigers, Valdez could push for playing time in the middle infield while David Hamilton (finger) is on the injured list.

Sogard will start at shortstop and bat ninth in Sunday's game against the Tigers.

The switch-hitting Sogard has now started in three of the Red Sox's four games since being called up from Triple-A Worcester on Thursday, with the switch-hitting infielder's lone absence from the lineup coming Saturday against All-Star southpaw Tarik Skubal. While David Hamilton (finger) is on the shelf, Sogard could have the opportunity to see near-everyday playing time in the middle infield, though Romy Gonzalez and Enmanuel Valdez loom as threats to poach starts from him.

Keith is out of the lineup for Sunday's game against the Red Sox, Evan Woodbery of MLive.com reports.

Keith is mired in an 0-for-14 slump and will sit Sunday for the second time in Detroit's past three games. Zach McKinstry will receive another start at second base while batting seventh.

Horwitz went 3-for-5 with a home run, a walk, two total runs and three total RBI against the Twins in Saturday's 15-0 victory.

Horwitz was a key part of a massive 23-hit performance by Toronto's offense. He started at third base and hit a two-run homer in the first inning along with a run-scoring single in the third. Prior to Saturday, Horwitz had just one RBI over his previous nine games.

Wagner went 5-for-6 a home run, a double, three runs and two RBI in Saturday's 15-0 mauling of Minnesota.

Among Wagner's knocks were a solo shot to right field in the sixth inning and a run-scoring double in the ninth. The five hits set a Toronto franchise record for a rookie and marked Wagner's fifth multi-hit effort through 16 career games. The 26-year-old is slashing an outstanding .357/.379/.571 with two home runs, eight RBI and eight runs through 16 big-league contests.

Morel went 2-for-4 with a walk, an RBI and two runs scored Saturday against the Padres.

Morel led off for the first time as a Ray, stepping into the role in the absence of Yandy Diaz (knee). Morel played a key role in rallies in the second and fourth innings, giving him at least one hit in seven of his last 10 starts. In that span, he's gone 10-for-39 with a 38 percent strikeout rate, though he's still managed three RBI and six runs scored.
