Mayfield replaced shortstop Carlos Correa after Correa left Monday's game with back discomfort.

Mayfield started at second base to give Jose Altuve a break but needed to adjust when Correa departed after his first-inning at-bat. Correa is listed as day-to-day, so Mayfield, who was called up to replace injured utility infielder Aledmys Diaz (head), could get some at-bats while Correa mends.

Marte went 1-for-3 with a two-run home run and a walk in the Diamondbacks' 5-3 win over the Rockies on Monday.

Marte's breakout campaign continues, as he checked in with his 26th long ball of the season in this contest with a two-run shot off Chi Chi Gonzalez in the sixth inning. He's blossomed into a star in his age-25 season, as Marte now sports a phenomenal .320/.382/.573 slash line across 529 plate appearances.

Polanco went 2-for-3 with a solo home run, a double, three runs and two RBI in the Twins' 6-4 loss to the White Sox on Monday.

Polanco continued his recent hot streak, as he cranked his 18th home run of the year off Aaron Bummer in the seventh inning and also slapped his 33rd two-bagger of the season, giving him four multi-hit efforts in his last five games. The 26-year-old is enjoying a career-best season at the dish, as he's now slashing .296/.358/.494 across 555 plate appearances.

Rodriguez went 2-for-4 with a solo home run in Monday's 5-4 loss to the Astros.

It was Rodriguez's eighth home run of the season but just his second since May 14. The 27-year-old cooled off dramatically after a hot start to the season, and he's now hitting .224 following Monday's two-hit effort. Rodriguez will offer infield depth with occasional power the rest of the year.

Altuve is not in the lineup Monday against the Tigers, Hunter Atkins of the Houston Chronicle reports.

Altuve will get what appears to be a well-deserved day off after starting the past 25 games, slashing .352/.419/.676 with nine home runs, 20 RBI, two stolen bases and an 11:13 BB:K during that stretch. Per Brian McTaggart of MLB.com, Jack Mayfield is starting at the keystone and hitting eighth in place of Altuve on Monday.

Castro is not in the lineup Monday against Astros.

Castro has started four of the past five games, going 6-for-16 with a home run and four RBI during that stretch. Ronny Rodriguez is starting at the keystone in his place.

Mayfield was recalled from Triple-A Round Rock on Monday, Chandler Rome of the Houston Chronicle reports.

Mayfield will provide the Astros with infield depth while Aledmys Diaz (head) spends time on the injured list. The 28-year-old Mayfield has struggled during his limited time in the majors this season (.143/.163/.310 in 43 plate appearances), though he's been hot since the start of August at Triple-A, slashing .333/.353/.730 with seven home runs in 15 games. Cy Sneed was sent to the minors in a corresponding move.

Rojas is not in Monday's lineup against the Rockies.

Rojas is 6-for-21 (.286) with zero home runs and one steal in seven games since making his big-league debut. Jarrod Dyson will start in right field, hitting leadoff.

Marte (back) is starting in center field and hitting second Monday against the Rockies.

This is excellent news, especially for those in weekly leagues, as Marte can now be deployed with confidence after missing two games with lower-back tightness. He is hitting .364 with two home runs and three steals in 13 games this month.

Chavis (shoulder) was spotted fielding grounders during a pregame workout Sunday, Bill Koch of The Providence Journal reports.

It's a good sign that Chavis was able to resume light baseball activities less than a week after landing on the 10-day injured list, but his ability to swing a bat without any discomfort will be the real test for his health. Chavis is eligible to return from the IL during the Red Sox's weekend series in San Diego this weekend, but he'll need to ramp up the intensity of his workouts in the next few days to guarantee his availability.
