Rizzo (arm) suffered a fracture to the radial neck of his right arm in Sunday's 9-3 loss to the Red Sox and could miss 4-to-6 weeks, Ken Rosenthal of The Athletic reports.

Rizzo suffered the injury in the seventh inning, when he collided with Red Sox pitcher Brennan Bernardino while running to first base. With the Yankees off Monday, Rizzo appears likely to be placed on the 10-day injured list Tuesday. In Rizzo's absence -- which could extend until after the All-Star break -- DJ LeMahieu could serve as the primary replacement at first base, while Oswaldo Cabrera picks up some extra starts at the hot corner.

Smith is out of the lineup for Monday's game against the Blue Jays.

With southpaw Yusei Kikuchi taking the hill for Toronto, the lefty-hitting Smith will give way to Bobby Dalbec at first base. Expect the two to form a platoon at the position until Triston Casas (ribs) returns from the 10-day injured list, perhaps shortly before the All-Star break.

Horwitz is out of the lineup for Monday's game versus the Red Sox.

Horwitz had started each of the last seven games versus right-handers upon his promotion from Triple-A Buffalo on June 7 and batted either first or second in all of those contests, but he will begin Monday's series opener on the bench. Davis Schneider gets the call at second base and will serve as the Blue Jays' leadoff batter against Red Sox right-hander Nick Pivetta.

Smith went 1-for-4 with a stolen base and a run scored in Sunday's 9-3 win over the Yankees.

The Red Sox stole a franchise-best nine bases in this contest, and even the not-so-speedy Smith got in on the fun. The first baseman hasn't done much in June, going 9-for-34 (.265) with two extra-base hits and seven walks over 12 contests. It's still an improvement on his .217/.323/.313 slash line through 133 plate appearances this season, and he's added just two home runs, 19 RBI, 12 runs scored and five doubles. Smith remains in a strong-side platoon role at first base, and that'll likely continue until Triston Casas (ribs) returns in July.

Soderstrom went 4-for-8 with a two-run home run and an additional run scored as the Athletics were swept in Sunday's doubleheader versus the Twins.

Soderstrom had three of his hits, including the homer, during the nightcap. He's hit safely in 10 of his last 11 games, going 13-for-38 (.342) in that span. The 22-year-old is up to a .250/.357/.464 slash line with five homers, 13 RBI, nine runs scored and three doubles over 31 contests. Soderstrom continues to see steady playing time at first base against right-handed pitchers, and he could push for closer to an everyday role if he continues to hit well.

Santana went 2-for-3 with a two-run home run, a walk and a stolen base in a 6-2 win over the Athletics in Game 1 of Sunday's doubleheader.

Santana also went 1-for-3 with a double, a walk and a run scored in the nightcap. The first baseman is batting .326 (15-for-46) with three homers and two steals over 13 contests in June, a stretch that's helped him claim a starting role at first base since Alex Kirilloff was optioned to Triple-A St. Paul. Santana is at a .235/.316/.425 slash line with 11 homers, 36 RBI, 26 runs scored and two steals through 66 games this season.

Locklear went 1-for-4 with a solo home run during Sunday's 5-0 win over the Rangers.

Locklear has safely reached base in five consecutive games and has generated a hit in six of his eight big-league contests. The 23-year-old chipped in a solo home run off Jose Leclerc in the seventh inning, marking Locklear's second homer since being called up June 8. Locklear has started in all but one of Seattle's games since his promotion, filling in at first base for Ty France (heel), who's expected to return from the IL as soon as Tuesday.

Vaughn went 3-for-5 with a two-RBI single, an RBI groundout and a run scored during Sunday's 12-5 loss to Arizona.

Vaughn participated in four of the White Sox's five runs, most of which came during the ninth inning when Vaughn plated Tommy Pham and Martin Maldonado with a single before coming around to score himself. On the year, Vaughn is slashing .234/.289/.391, each of which would be a career low. However, he's been hot during June, batting .364 with five homers, 12 RBI and 12 runs.

Rizzo (arm) suffered a right lower-arm injury in Sunday's 9-3 loss to the Red Sox, Gary Phillips of the New York Daily News reports.

Rizzo went down in a heap after a collision with Boston reliever Brennan Bernardino at first base in the top of the seventh inning, suffering an apparent right arm injury. The first baseman will see the team doctors and undergo imaging to determine the severity of the injury in New York on Monday.

Schanuel went 1-for-2 with a solo homer, two walks and two runs scored in Sunday's loss to the Giants.

Schanuel belted a solo shot in the second inning for his seventh home run of the year and third in his last 10 games. However, he's gone just 8-for-34 (.235) during that span. Sunday was Schanuel's third straight game with multiple walks. He's now slashing .219/.301/.348 with 13 extra-base hits and 23 RBI through 63 games.
