Seager (back) is heading back to Arlington to see the Rangers' back specialist, Jeff Wilson of AllDLLS.com reports.

Seager won't be available for at least the team's first game in Colorado as the Rangers begin a three-game set against the Rockies on Monday. The 32-year-old underwent an MRI on Sunday, and the results are still pending. In his absence, Ezequiel Duran has made back-to-back starts at shortstop, and he'll likely hold down that spot if Seager is forced to miss additional action moving forward.

The Mariners called Emerson up from Triple-A Tacoma and will have him stsart at third base and bat ninth in Sunday's series finale versus the Padres, Daniel Kramer of MLB.com reports.

Emerson was summoned for his MLB debut after the Mariners placed Brendan Donovan (groin) on the 10-day injured list Sunday. The 20-year-old Emerson posted a .255 average with seven home runs, 26 RBI, 26 runs scored and 10 stolen bases over 145 at-bats in 38 contests with Tacoma prior to his promotion. In Donovan's absence, Emerson is expected to operate as Seattle's primary third baseman.

Pena (hamstring/neck) rejoined the Astros on Sunday and will travel with the team for Monday's series opener in Minnesota, Brian McTaggart of MLB.com reports.

Pena missed a couple games during his rehab assignment due to a neck issue, but he returned to action for Double-A San Antonio this weekend and now appears ready to rejoin the active roster. The 28-year-old shortstop could end up taking the roster spot of Jose Altuve, who will soon be placed on the injured list after being diagnosed with an oblique strain.

The Mariners are expected to call up Emerson from Triple-A Tacoma on Sunday, Ryan Divish of The Seattle Times reports.

The 20-year-old is Seattle's top prospect and is traveling to join the big club after being scratched from Tacoma's lineup Sunday. It'll be the first taste of the majors for Emerson after inking an eight-year, $95 million extension with the Mariners in late March. Brendan Donovan (undisclosed) is sitting out a second consecutive game Sunday after recently returning from a groin strain, which could mean that third base is Emerson's clearest path to playing time. It's not yet clear if Donovan will require a trip to the IL, however.

Seager (back), who is out of the lineup for Sunday's game against the Astros, has been sent to undergo an MRI, Jeff Wilson of AllDLLS.com reports.

Seager is sitting Sunday for a third consecutive day due to back spasms, which have been considered minor but are apparently serious enough to send him for medical imaging. Ezequiel Duran is picking up a second straight start at shortstop Sunday and could get an extended look there if Seager misses additional time.

Seager (back) is not in Texas' starting lineup Sunday versus the Astros.

Seager is out of the lineup for the third straight day, as he's said to be dealing with minor back spasms. The veteran shortstop is considered day-to-day, and it's unclear if he's available off the bench. Ezequiel Duran is starting at shortstop for the second straight day in Seager's stead.

Pena (hamstring/neck) could be reinstated from the 10-day injured list ahead of Monday's game at Minnesota, Brian McTaggart of MLB.com reports.

The 28-year-old shortstop resumed his rehab assignment with Double-A Corpus Christi on Friday after neck soreness forced him to miss a couple games earlier in the week, and he could rejoin the Astros on Monday for the start of a 10-game road trip. Pena, who has been on the IL for a month due to a hamstring strain, has gone 2-for-11 with two doubles in three contests during the rehab stint.

The Rays recalled Williams from Triple-A Durham on Sunday.

The 22-year-old made Tampa Bay's Opening Day roster but was demoted back to Durham after going 3-for-23 with nine strikeouts in his first seven MLB games. Taylor Walls reclaimed the starting job at shortstop once he was healthy, but Williams is returning to the majors with Jake Fraley (hernia) heading to the IL. Walls has a .212/.310/.273 slash line in 118 plate appearances, so Williams could get some opportunities to prove he can handle big-league pitching, and the additional infield depth could free up Richie Palacios for more time in right field.

Montgomery went 1-for-4 with a solo home run during the White Sox's 8-3 win over the Cubs on Saturday.

Montgomery was responsible for one of five home runs off Jameson Taillon on Saturday, with the former's taking place in the third inning to give the White Sox a 5-0 lead. Montgomery has gone deep in back-to-back games and is up to 13 home runs on the season, which is sixth most in the American League and second on the White Sox behind only Munetaka Murakami (17). Montgomery sports an .864 OPS with one steal, 31 RBI and 22 runs scored over 183 plate appearances this season.

Story is seeking additional opinions about whether surgery is needed for his sports hernia, Tim Healey of The Boston Globe reports.

Story was placed on the 10-day IL on Saturday due to the issue, which he's reportedly been dealing with for much of the season. The expected length of his absence should become clearer once it's determined whether or not he'll need to go under the knife. Story said Saturday that he'll likely be out 6-to-10 weeks if surgery is indeed required.
