McMahon is out of the lineup for Sunday's game against the Red Sox.

With ace southpaw Garrett Crochet on the bump for Boston, McMahon will head to the bench along with fellow left-handed hitters Trent Grisham and Austin Wells. McMahon's absence will open up third base for Amed Rosario, who will bat fifth.

Eaton is out of the lineup for Sunday's game against the Yankees.

Eaton will take a seat for the series finale after he made starts out of the outfield in each of the last four games while going 5-for-12 with a home run, a double, a walk, a stolen base, two RBI and three runs. Boston will go with a starting outfield of Jarren Duran, Ceddanne Rafaela and Rob Refsnyder from left to right Sunday.

Alexander was removed from Sunday's game against the Twins after being hit in the left elbow by a pitch in the top of the fourth inning, Jack Sommers of SI.com reports. He finished 0-for-1 with a run scored.

Alexander appeared to be in significant pain after being hit, but he was able to take his base before checking out of the game in the bottom half of the inning. The Diamondbacks will likely send Alexander in for X-rays, but even if he avoids a fracture, he could be dealing with enough swelling or soreness to keep him out of the lineup for a few days. Alexander had settled into an everyday role for the Diamondbacks in the aftermath of the July 31 trade deadline, batting .250 with seven home runs, one stolen base, 21 runs and 22 RBI in 41 games since then.

Arenado (shoulder) will be activated from the 10-day injured list ahead of Monday's game against the Reds, Derrick Goold of the St. Louis Post-Dispatch reports.

The veteran third baseman has gone 1-for-13 during his minor-league rehab assignment with Double-A Springfield and will return to St. Louis on Monday after an absence of over six weeks due to a shoulder strain. Arenado is in the midst of the worst season of his career with a .245/.294/.366 slash line in 96 games.

Karros is out of the lineup for Sunday's game against the Padres.

Karros will hit the bench after he started in each of the last six games while going 2-for-20 with one walk and six strikeouts. Kyle Farmer will step in for Karros at third base and will bat seventh.

Muncy is out of the lineup for Sunday's game against the Giants.

The left-handed-hitting Muncy will be held out of the lineup for second time in four games while the Dodgers face off against another left-handed starter (Robbie Ray). Enrique Hernandez will fill in for Muncy at third base and will bat eighth.

Baty is out of the lineup for Sunday's game against the Rangers, Anthony DiComo of MLB.com reports.

It's the third baseman's fifth absence in New York's past six games, with all of those absences coming versus left-handed starting pitchers. Baty has been filling the strong side of a platoon at third base and has a .762 OPS through 10 games in September, which should be enough for him to retain that role despite the recent downturn in playing time.

Rivera is out of the lineup for Sunday's game against the Blue Jays.

Rivera started at third base in each of the last three games, but he could fade into more of a part-time role after Tyler O'Neill was reinstated from the injured list Friday. Though O'Neill served as the Orioles' designated hitter in his first two games upon his return, he may see more time in right field moving forward, which would likely result in Jeremiah Jackson poaching starts from Rivera at third base. Since being promoted from Triple-A Norfolk on Aug. 27, Rivera has slashed a weak .265/.265/.286 over 13 games.

Machado is out of the lineup for Sunday's game against the Rockies.

In what appears to be a planned rest day, Machado will get a first day off of the season after starting in each of the Padres' first 149 games of the campaign. Jose Iglesias will step in at third base for Machado, who went 4-for-10 with two home runs, two walks, four RBI and four runs through the first three games of the series.

House is out of the lineup for Sunday's game against the Pirates, Mark Zuckerman of MASNSports.com reports.

House will take a seat Sunday after a run of five straight starts, during which he went 4-for-17 with a double and a solo homer. Paul DeJong is manning the hot corner and batting seventh in the series finale for the Nationals.
