Vargas slashed .276/.321/.454 with 14 home runs and 29 steals in 97 games for Single-A Down East.

While the surface stats appear promising for the 19-year-old middle infielder, his 0.24 BB/K, 22.0 percent hard-hit rate and 25.5 percent soft-contact rate portend struggles in the upper levels. Vargas is an aggressive hitter who doesn't make consistent hard contact, so he projects to log low on-base percentages and potentially low batting averages. Even so, he could potentially log a 20/20 season or two if he finds his way into an everyday role. Vargas' projects to be a quality defender at second base or a passable defender at shortstop, and his most likely role is utility infielder who sometimes ascends to regular duty depending on injuries and performance.

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

Sogard led off the fourth inning with a double and scored Boston's third run. He's 3-for-7 with three doubles over the last two games, which included a turn at shortstop in the second game of Sunday's doubleheader sweep of the Twins. Sogard will operate as a utility infielder, while Romy Gonzalez, who started at third base the first three contests after Rafael Devers (shoulder) landed on the injured list, appears to be the preferred option at the hot corner.

Grissom started at second base and went 0-for-3 with an RBI in Monday's 4-1 win over Toronto.

Grissom knocked in Boston's first run with a sacrifice fly in the second inning. It was his first RBI since rejoining the Red Sox late last week. He's been in the lineup three consecutive days, including the nightcap of Sunday's doubleheader, and should get plenty of opportunities at second base over the final week of the regular season. The position, which he had been expected to fill prior to injuries flaring up in spring training, has been a revolving door for Boston in 2024. Grissom is looking to build off a month of sustained success at Triple-A Worcester, for whom he batted .366/.489/.549 with 18 walks, four home runs, 18 RBI and 17 runs scored over 21 games before his elevation to the majors.

Arizona manager Torey Lovullo said Monday the decision to hold Marte out of that day's starting lineup was "preventative" and described the second baseman as being in the "red zone," Alex Weiner of Arizona Sports reports. "The left leg, it probably wasn't 100% when he came back, if you guys studied the swings enough, you could recognize he was protecting that space," the manager said.

Lovullo added that Marte was available off the bench, and the infielder entered as a pinch hitter in the eighth inning and finished the game at second base. The Diamondbacks lost to the Giants and are now one-and-a-half games ahead of Atlanta for the final wild card spot with five games left (six for Atlanta). Reading between the lines of Lovullo's comments, Monday's lighter-than-normal effort sets up Marte to finish out the season as an everyday lineup presence.

Schmitt went 1-for-3 with a solo home run and a walk in Monday's 6-3 win over the Diamondbacks.

Schmitt went yard in the fourth inning to give the Giants a 4-2 lead. The infielder has gone 6-for-14 (.429) with four RBI since he rejoined the major-league roster last week. For the season, he's posted a .240/.267/.460 slash line with six homers, 14 RBI, 10 runs scored, two doubles and one triple over 36 major-league contests.

The Diamondbacks outrighted Guillorme to Triple-A Reno on Monday.

Guillorme was designated for assignment Friday and will head to the minors after failing to draw interest on waivers. The 29-year-old has slashed .205/.301/.273 with 10 RBI, four stolen bases and 14 runs scored over 79 games across stops with Arizona, Atlanta and the Angels so far in 2024.

The Blue Jays reinstated Martinez from his 80-game suspension Monday and optioned him to the rookie-level Florida Complex League.

Martinez was handed an 80-game ban in June for violating MLB's performance-enhancing drugs policy and began a rehab assignment Sept. 6 at Triple-A Buffalo. With Buffalo's season ending Sunday and the Blue Jays not eager to open up a spot for him on the active roster for the final week of the season, Martinez will head to Toronto's spring training complex in Florida for additional work. Despite the suspension presenting a bump in the road in his development, the 22-year-old performed well in 74 games at Triple-A Buffalo this season, batting .267 with 17 home runs and 49 RBI. Martinez should get every opportunity in the spring to compete for a spot on Toronto's Opening Day roster.

Walton is not in the lineup for Monday's contest versus the Diamondbacks.

After being given four straight starts at second base, Walton has now started just one of the last four contests at the position. The Giants have started four different players at the keystone over that time, with Casey Schmitt getting the call for Monday's series opener.

Gonzalez is out of the lineup for Monday's game against the Blue Jays, Ian Browne of MLB.com reports.

After Rafael Devers suffered a right shoulder injury Friday before landing on the injured list a day later, Gonzalez picked up each of the ensuing three starts at third base, going 3-for-10 with a home run, a stolen base and five RBI across those contests. Though he'll give way to Nick Sogard at the hot corner Monday, Gonzalez still looks to be the Red Sox's preferred option at the position entering the final week of the season.

Marte is out of the lineup for Monday's game against the Giants.

Marte will hit the bench for the third time since he was reinstated from the 10-day injured list Sept. 6 after missing three weeks with an ankle sprain. Kevin Newman will step in at second base in place of Marte, who is slashing .271/.407/.625 with five home runs, one stolen base, 12 RBI and nine runs across 14 games in September.
