The Rangers activated Burger (wrist) from the 10-day injured list Monday.

Burger missed the past two weeks of action with a sprained left wrist but has been cleared to return to action after facing live pitching at the Rangers' spring training facility. The 29-year-old will likely give way to Rowdy Tellez at first base against most right-handers, though Burger may not serve as a strict platoon player, especially with Tellez having struggled to produce at the plate recently.

Seymour is not in the lineup for Monday's game against the Mariners.

It's righty Luis Castillo toeing the rubber for the Mariners, but the left-handed-hitting Seymour will nonetheless begin the festivities on the bench. Yandy Diaz is handling first base and Richie Palacios will be the designated hitter for the Rays.

Mountcastle is absent from the lineup for Monday's contest in San Diego.

Mountcastle started each of the previous five games, but he'll take a seat against righty Dylan Cease and the Padres on Monday. Samuel Basallo will serve as the designated hitter and Coby Mayo will handle first base for Baltimore in the series opener.

Vaughn is out of the lineup for Monday's game against the Phillies.

After going just 5-for-30 (.167 average) with two walks while starting in each of the past eight games, Vaughn will exit the lineup and receive a mental reset as the Brewers kick off a three-game set with the Phillies. Jake Bauers will fill in for Vaughn at first base.

Burleson (wrist) was spotted playing catch on the field prior to Monday's game against the Athletics, Derrick Goold of the St. Louis Post-Dispatch reports.

St. Louis placed Burleson on the 10-day injured list Friday due to right wrist inflammation, but after getting an injection to relieve discomfort, he's already started throwing again. Burleson remains hopeful to be activated from the IL around when he's first eligible to return Sept. 8.

Bernabel (knee/quadriceps) remains out of the lineup for Monday's game against the Giants.

Bernabel will miss a second straight start after exiting Saturday's 4-3 loss to the Cubs with a bruised left knee and quad. He is considered day-to-day. Orlando Arcia will cover first base and bat ninth for the Rockies in Bernabel's stead.

The Mariners released Solano on Monday.

After playing regularly against left-handed pitching for most of the first half of the season, Solano saw his at-bats fall by the wayside once the Mariners acquired Josh Naylor from the Diamondbacks on July 24 and installed him as their everyday first baseman. Since Naylor's debut, Solano has started just three times and appeared in only five games. The Mariners opted to cut him loose to make room on the roster for Leo Rivas, who brings more defensive flexibility to the table.

Kurtz (oblique) is out of the lineup for Monday's game against the Cardinals.

An MRI on his oblique came back clean Saturday, but Kurtz will miss a third straight game while he deals with lingering discomfort. Tyler Soderstrom will cover first base Monday in Kurtz's absence.

The Astros designated Davidson for assignment Monday.

Davidson will give up his spot on the 40-man roster to right-hander Luis Garcia (elbow), who was activated from the 60-day injured list ahead of his scheduled start Monday versus the Angels. Since being claimed off waivers from the Athletics in July and getting sent to Triple-A Sugar Land, Davidson is hitting .207 with a 34.4 percent strikeout rate in 22 games.

Reds manager Terry Francona said that Steer is not in Monday's lineup versus the Blue Jays in part due to a nagging leg injury that's bothered the player for two months, Charlie Goldsmith of Fox 19 Now Cincinnati reports.

The injury doesn't sound like anything that will keep Steer out more than a day or two, but the call-up of top prospect Sal Stewart -- who is making his major-league debut Monday at first base -- allows Steer to get off his feet for a day. Consider Steer day-to-day.
