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

The rookie corner infielder will sit for a third straight game as he continues to manage a bruised left knee and quad. Kyle Farmer is starting at first base Tuesday in place of Bernabel.

Steer (leg) remains out of the lineup for Tuesday's game against the Blue Jays.

Steer will miss a second straight start because of a lingering leg issue. He was able to appear in Monday's game off the bench and presumably will be available again Tuesday. Sal Stewart is again handling first base and batting sixth for the Reds.

Steer (leg) entered Monday's game as a replacement at first base and went 0-for-1 in a 5-4 win over Toronto.

Steer opened the game on the bench due to a nagging leg issue, which is purportedly not serious. His departure from the lineup opened a slot for prospect Sal Stewart, who made his MLB debut as the starting first baseman. Steer, who eventually replaced Stewart for defensive purposes, seemingly will be ready to play a full nine innings Tuesday.

Stewart started at first base and went 1-for-3 with a run scored in Monday's 5-4 win over the Blue Jays.

Stewart was called up Monday and made his big-league debut while filling in at first base for Spencer Steer (leg). The highly regarded prospect singled in his first at-bat and scored on a Ke'Bryan Hayes double. In addition to first base, Stewart could see time at second base, DH and third base when Hayes needs a breather.

Locklear went 1-for-2 with a solo home run and a walk in Monday's 7-5 extra-inning loss to the Rangers.

Locklear hit his third homer of the year in the second inning. His last long ball also came against Texas on Aug. 11. The first baseman's blast snapped an 0-for-20 skid over his previous seven games. Despite those struggles, he's set to start a majority of the time at first base following Pavin Smith's season-ending quad injury. Locklear is batting just .163 with six RBI, nine runs scored and two stolen bases over 97 plate appearances, so he still has plenty of work to do to prove himself in the majors.

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.

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.

Johnston is out of the lineup for Monday's game against the Nationals.

The Nationals are sending lefty Andrew Alvarez to the hill for the series opener, so Johnston will head to the bench along with another lefty-hitting lineup regular in Liam Hicks. Johnston closed August with a .293/.328/.414 slash line, one home run, one stolen base, seven RBI and five runs over 23 games.
