Estrada is absent from the lineup for Tuesday's game in Boston.

It's a routine day off for Estrada, who had started the previous 13 contests. Orlando Arcia will cover first base and bat eighth for the Rockies.

Yankees manager Aaron Boone said Tuesday that he has no plans to regularly use LeMahieu at third base, and he views the veteran infielder as a bench bat, Chris Kirschner of The Athletic reports.

Jazz Chisholm will make the move from third base back to his more natural position at second base, where LeMahieu had been serving as the Yankees' primary starter since returning from the injured list May 13. Though LeMahieu has ample experience at third base, he won't end up taking over for Chisholm at the hot corner, with Boone noting that it's a challenge for the 36-year-old to physically play the position at this stage of his career. Oswald Peraza will draw the nod at third base Tuesday versus the Mariners and looks like the favorite to see the bulk of the starts at that spot for the time being.

Koss (hamstring) is set to resume baseball activities this week and be re-evaluated after the All-Star break, per MLB.com.

Koss was placed on the 10-day injured list July 1 due to a left hamstring strain. The 27-year-old infielder will use the All-Star break to continue his recovery before the Giants determine his next steps, though his return to baseball activities is an encouraging sign. Koss has been effective in a reserve role for the Giants, slashing .265/.305/.357 with 12 runs scored, 12 RBI, two home runs and two stolen bases across 108 plate appearances.

Yankees manager Aaron Boone said Tuesday in his appearance on Jomboy Media's "Talkin' Yanks" podcast that Chisholm (shoulder) will move back to second base.

Boone had already seemed to be leaning toward shifting Chisholm to second base, and Chisholm's bout with right shoulder soreness likely cinched the decision. Chisholm was out of the lineup for Sunday's game versus the Mets as he battles through the nagging shoulder problem, but he'll be back in the lineup Tuesday versus the Mariners and will cover the keystone. Oswald Peraza is slated to start at third base Tuesday.

Alexander started at second base and went 1-for-4 in Monday's 6-3 win over San Diego.

Alexander was a late addition to the starting lineup after Ketel Marte (groin) was scratched. Marte is hoping to play Tuesday, but Alexander remains on call if needed.

Arizona manager Torey Lovullo said after Monday's 6-3 win over the Padres that Marte (groin) has a good chance Tuesday, Jose M. Romero of The Arizona Republic reports.

Marte was held out for the series opener due to right groin tightness, but the issue isn't expected to keep him sidelined for long. Blaze Alexander filled in at second base for Marte on Monday, going 1-for-4.

Keith went 3-for-4 with two doubles, a solo home run and an additional run scored in Monday's 5-1 win over the Rays.

Keith batted leadoff and delivered his second three-hit effort of the season, which included his seventh home run of the year. His other three-hit performance came just five days ago, and the 23-year-old is now batting a robust .450 this month with five extra-base knocks across six games. The left-hand hitting Keith is still sitting regularly against southpaws, but the youngster is developing into a dynamic offensive player when facing righties.

Marte was scratched from Monday's lineup against the Padres due to right groin tightness, Steve Gilbert of MLB.com reports.

The Diamondbacks are considering the star second baseman day-to-day. Marte will presumably be re-evaluated Tuesday to determine his availability for the rest of the series. Blaze Alexander, who is drawing the start Monday night at second base, would be in line for more opportunities if Marte is forced to miss additional time.

Marte (undisclosed) was scratched from Monday's lineup against the Padres, Aaron Hughes of SI.com reports.

Marte was originally set to play second base and bat second in the team's series opener with San Diego, but he's been removed for an undisclosed reason. More information on his status will likely come in the near future, but in the meantime, Blaze Alexander will start at second base and bat ninth Monday.

The Giants optioned Fitzgerald to Triple-A Sacramento on Monday.

With Casey Schmitt (hand) back from the injured list, Fitzgerald will head back to the minors. He could get another look later this summer, but for now Fitzgerald will receive regular playing time with Sacramento.
