The Blue Jays selected Wagner's contract from Triple-A Buffalo on Monday.

One of the players acquired from the Astros in the Yusei Kikuchi trade, the 26-year-old Wagner has slashed .315/.432/.444 with six home runs and three stolen bases over 77 games at the Triple-A level in 2024. The left-handed hitting utility player should see regular playing time at least against right-handed pitching, likely bouncing around between second base, third base and first base.

The Red Sox designated Westbrook for assignment Monday, Jen McCaffrey of The Athletic reports.

Westbrook is the 40-man roster casualty with the Red Sox needing to clear some space in advance of Monday's game against the Rangers. The 29-year-old utility player went just 6-for-40 at the plate during his time with the Red Sox before being sent back to Triple-A Worcester on July 31.

Mead will start at designated hitter and bat seventh in Monday's game against the Astros, Steve Carney of StPeteNine.com reports.

After picking up starts in four of the Rays' last five matchups with right-handed pitching, the righty-hitting Mead will stick in the lineup Monday while the Astros send southpaw Framber Valdez to the hill. Though he appears to be challenging Taylor Walls for a regular spot in the Tampa Bay infield, Mead will likely need to show better production at the plate before he fully displaces Walls. Through his first six games in August, Mead has gone just 2-for-18 with no extra-base hits and one walk.

Lowe is out of the lineup for Monday's game against the Astros, Steve Carney of StPeteNine.com reports.

After going 3-for-21 at the dish over his last five starts, Lowe will take a seat for the first time since July 26 while the Astros send southpaw Framber Valdez to the hill. The Rays will counter with a right-handed-heavy lineup featuring Curtis Mead at designated hitter in place of the lefty-hitting Lowe.

Massey (back) will start at designated hitter and bat leadoff in Monday's game versus the Twins.

Massey was scratched from the lineup ahead of Saturday's 8-3 win over the Cardinals due to back tightness. His back has often been an issue for him this season, but Massey is feeling well enough after a scheduled team off day Sunday to give it a go in the series opener in Minnesota.

Polanco went 3-for-5 with a solo homer, a double and two runs scored in Sunday's win over the Mets.

Polanco opened up the scoring with a solo home run in the second inning off Luis Severino. He later doubled and scored in the sixth and singled in the eighth for his second three-hit effort of the season. Coming into Sunday, Polanco had just three hits in 22 at-bats this month while striking out eight times over that span. He's currently striking out at a 31.1 percent clip, which would be the highest mark of his career and the first time he's ever had a strikeout rate north of 30 percent. It's been a struggle for Polanco in his first year in Seattle, as he's slashing .211/.292/.352 with 11 homers, 30 RBI, 31 runs, three steals and a 30:99 BB:K in 318 plate appearances.

Gelof went 3-for-4 with a two-run home run and two doubles in Sunday's 8-4 win over the Blue Jays.

Gelof took Chris Bassitt deep in a six-run first inning and avoided striking out for the first time in eight August contests. He has tallied three multi-hit games in that span and his average now stands above the Mendoza Line at .201 for the first time since July 20. While the second baseman has certainly struggled in that department all season, he does have 15 homers and 14 steals across 378 plate appearances.

Gimenez went 0-for-3 with two walks, two stolen bases and one run scored in Sunday's 5-3 win over the Twins.

Gimenez had drawn just two walks over the previous 20 contests. He's started to run more lately with three steals over his last four contests, giving him 19 thefts on the year. The second baseman is at a .255/.305/.337 slash line with five home runs, 47 RBI, 49 runs scored, 17 doubles and a triple over 110 games. He's been better lately, batting .280 (33-for-118) since the start of July, though his power largely remains absent with no homers and six doubles in that span.

Sogard will start at third base and bat seventh in Sunday's game against the Astros, Jen McCaffrey of The Athletic reports.

Sogard will stick in the lineup for a sixth consecutive game, this time manning third base while Rafael Devers gets a rare rest day. The rookie's previous five starts came at second base and shortstop, and the Red Sox should continue to have a near-everyday role available for Sogard in the infield while he's swinging a hot bat and while Tyler O'Neill (lower leg) is on the shelf.

Stefanic will start at second base and bat ninth in Sunday's game against the Nationals, Rhett Bollinger of MLB.com reports.

Stefanic will pick up his fourth straight start, all of which have come against left-handed pitching. Though he's slashing .462/.500/.538 in eight games since being called up from Triple-A Salt Lake on July 30, Stefanic could be limited to a short-side platoon role in the infield now that Anthony Rendon has recently returned from the injured list.
