Lowe and the Red Sox agreed to a one-year contract Sunday, Jeff Passan of ESPN.com reports.

Lowe was granted his release from the Nationals on Saturday and has quicly found a new home in Boston. The 30-year-old had slashed .216/.292/.373 slash line with 16 home runs and one stolen base over 119 contests with Washington, where he had been handling an everyday role at first base. The Red Sox have struggled to find a consistent option at first base this season, and the left-handed-hitting Lowe could occupy the strong side of a platoon at the position with the right-handed-hitting Romy Gonzalez. Lowe owns a .732 OPS over 337 plate appearances versus right-handed pitching this season.

Guerrero went 2-for-4 with a solo home run during Sunday's 10-4 loss to Texas.

The Blue Jays batters were held in check for the most part by Nathan Eovaldi through seven innings, though Guerrero was able to break through with a solo shot to left-center field for his 21st homer of the season and sixth since the beginning of August. Guerrero has seen his numbers creep up with every passing month, and since the All-Star break he has slashed .368/.442/.702 with 11 doubles, 24 runs, nine home runs and 22 RBI over 129 plate appearances.

Manager Bruce Bochy said that Burger won't be available for at least a couple of days while he heads back to Texas to receive medical imaging on his left wrist, Shawn McFarland of The Dallas Morning News reports.

Burger exited Sunday's 10-4 win over the Blue Jays due to left wrist discomfort, and there's enough concern about his injury for him to leave the team for a more thorough evaluation. The 29-year-old will miss at least the first couple games of the Rangers' upcoming series in Kansas City while the specifics of the injury are determined.

Burger was removed from Sunday's game against the Royals due to left wrist discomfort, Shawn McFarland of The Dallas Morning News reports.

Burger went 1-for-3 with an RBI and a run scored before being replaced by a pinch hitter during the seventh inning. The severity of the injury remains unclear, so the first baseman should be considered day-to-day heading into Monday's series opener in Kansas City.

Mountcastle is out of the lineup for Sunday's game against the Astros.

Mountcastle started all eight games since coming off the injured list last week and has slugged two home runs and has posted a .851 OPS, but he'll take a seat for the series finale in Houston. Coby Mayo will continue to man first base for Baltimore, while top prospect Samuel Basallo is making his MLB debut at designated hitter.

Walker is out of the lineup for Sunday's game against the Orioles, Brian McTaggart of MLB.com reports.

It's a rare off day for Walker, who started the previous 30 games after spending a few days on the paternity list in early July. The first baseman is batting just .216 (11-for-51) in August but has four doubles, three homers and a 9:14 BB:K.

Goldschmidt (knee) will start at first base and bat sixth Sunday against the Cardinals.

Goldschmidt has been battling a knee sprain, but he'll return to the lineup for the first time since Tuesday. The veteran first baseman has a .716 OPS through 11 games in August, though he's gone just 3-for-24 outside of a three-hit performance Aug. 4 in Miami.

Pasquantino (illness) will start at designated hitter and bat third in Sunday's game against the White Sox.

After striking out during his first-inning at-bat in Saturday's 6-2 win, Pasquantino was pulled from the contest due to a heat-related illness. The 27-year-old appears to have responded well after getting rehydrated and resting up, prompting the Royals to clear him to re-enter the lineup for the series finale.

Mead is out of the lineup for Sunday's game against the Royals.

After bouncing between the corner infield spots over nine straight games and going 9-for-31 (.290) with one stolen base, five RBI and two runs, Mead will get a second straight contest off. The White Sox will go with Lenyn Sosa at first base and Miguel Vargas at the hot corner as they look to avoid a series sweep.

Santana is out of the lineup for Sunday's game against Atlanta.

Santana went 1-for-5 with a pair of walks while starting the first two contests of the series, but he'll retreat to the bench for the series finale. The 39-year-old looks to be fading into a part-time role, as he's now been out of the lineup five times in the Guardians' last eight games.
