Fermin went 1-for-4 with two RBI and a stolen base in Sunday's 10-4 loss to the Mariners.

Fermin has seen minimal playing time since he was recalled from Triple-A Memphis on Aug. 21 to replace Nolan Gorman. Over eight games since that date, Fermin has gone 3-for-15 (.200) with three walks, and his two-run single Sunday was the first time he plated a run in the majors all season. The infielder has a poor .148/.246/.197 slash line with no home runs, two stolen bases, six runs scored, a double and a triple over 69 plate appearances. He has a short-term path to playing time at second base as long as Brendan Donovan (foot) is out.

Gelof went 2-for-3 with a walk, an RBI and a stolen base in Sunday's 9-1 loss to the Tigers.

Gelof has posted a steal in back-to-back contests and has hit safely in five straight games. Over eight games in September, he's batting .310 (9-for-29) with three thefts. The second baseman has had a rough first full campaign in the majors, though a hot September wouldn't be unusual, as he slashed .273/.350/.455 over his last 28 games in 2023. This year, he's at a .209/.272/.369 slash line with 16 home runs, 22 steals, 44 RBI and 54 runs scored through 120 contests.

Semien went 2-for-5 with a solo home run, an additional RBI and a stolen base in Sunday's 7-4 win over the Angels.

Semien ended a 19-game homer drought when he led off the bottom of the first inning with a long ball. In that span, he batted a poor .205 (16-for-78) with three doubles, five RBI, 10 runs scored and two steals. He's started to turn things around with at least one hit in five straight games. The second baseman now has a .238/.308/.387 slash line, 19 homers, 67 RBI, 88 runs scored and six steals over 141 contests this season. He hasn't missed the 20-homer mark in a full-length campaign since 2018, and he has three weeks left to reach that milestone in 2024.

Guillorme will start at second base and bat ninth in Sunday's game against the Astros.

The lefty-hitting Guillorme had been on the bench in each of the last three contests while the Diamondbacks opposed left-handed starters, but he'll draw back into the starting nine Sunday versus Astros righty Justin Verlander. Despite his inclusion in the lineup, Guillorme's opportunities to play against righties will likely be more limited moving forward following Ketel Marte's return from the injured list.

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

Marte went 0-for-7 with a walk and four strikeouts as the designated hitter the past two games after being reinstated from the injured list Friday, and he'll receive a day off for the series finale in Houston. Luis Guillorme is starting at second base while Joc Pederson is back at designated hitter Sunday.

India was removed from Sunday's game against the Mets due to left elbow discomfort, C. Trent Rosecrans of The Athletic reports.

The second baseman went 0-for-3 with two strikeouts before exiting the contest. The severity of the injury is unclear, and India should be considered day-to-day heading into Monday's matchup with Atlanta.

Wisely is not in the lineup for Sunday's game against the Padres, Alex Pavlovic of NBC Sports Bay Area reports.

Wisely has gone 3-for-25 in his past 12 games and will sit for Sunday's series finale in San Diego. Marco Luciano is starting at second base and could be taking hold of a regular role at the position.

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

Turang doesn't operate in a strict platoon at second base, but he'll sit Sunday against Colorado southpaw Kyle Freeland. Andruw Monasterio will start at the keystone and bat ninth in the series finale.

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

Hoerner has gone 3-for-14 in his past four games and will receive a well-deserved day off Sunday after a run of 75 consecutive starts. Miles Mastrobuoni will take over at the keystone and bat ninth.

Triolo is out of the lineup for Sunday's game against the Nationals, Kevin Gorman of TribLive.com reports.

Triolo will take a seat after making 12 consecutive starts, and he had a .282/.391/.436 slash line with a homer, two steals, eight RBI and six runs during that span. Isiah Kiner-Falefa will shift to the hot corner while Alika Williams receives a start at shortstop.
