Mateo (hamstring) appears on track to be activated from the 60-day injured list Sept. 1, Rich Dubroff of BaltimoreBaseball.com reports.

The Orioles' active roster will expand from 26 to 28 men Sept. 1, which should make it easier for the club to facilitate Mateo's reinstatement. Mateo, who has resided on the IL since early June due to an inflamed left elbow and then a strained left hamstring, has slashed .375/.400/.500 with one home run and two stolen bases through the first seven games of his rehab assignment at Triple-A Norfolk. Mateo projects to fill a utility role for Baltimore once he's activated.

Baez isn't in the starting lineup for Monday's game against the Athletics, Chris McCosky of The Detroit News reports.

Baez will begin Monday's matchup on the bench, which allows Trey Sweeney to start at shortstop and Wenceel Perez to man center field. Baez appears to be in need of a reset after going 4-for-22 with two RBI, two runs scored and seven strikeouts over his last seven games.

Kiner-Falefa is out of the lineup for Monday's game against the Cardinals.

Kiner-Falefa will retreat to the bench for the series opener in St. Louis after he started in each of the last three contests. Jared Triolo will cover third base Monday in Kiner-Falefa's stead, which opens up shortstop for Liover Peguero.

Montgomery is out of the lineup for Monday's game against the Royals.

The White Sox are running out a full lineup of right-handed-hitting options to counter Royals southpaw Noah Cameron, so Montgomery will join fellow left-handed hitters Kyle Teel, Mike Tauchman and Andrew Benintendi on the bench. Montgomery had started in each of Chicago's previous four games and slugged home runs in the last three contests, bringing his OPS up to .829 over 160 plate appearances since he was promoted from Triple-A Charlotte on July 4.

Ortiz (hamstring) fielded grounders Monday and hopes to be activated from the 10-day injured list when first eligible Sept. 1, Adam McCalvy of MLB.com reports.

Ortiz suffered a left hamstring strain last Thursday and was placed on the IL on Friday. He'll have to show he can ramp up his running without issue before convincing the Brewers he'll need only a minimum-length absence, but Ortiz seems to be doing well during the early stages of his recovery.

Yankees manager Aaron Boone reiterated Monday that Volpe is "our shortstop" and will play "regularly," despite being out of the lineup for a second straight day as New York opens its series against the Nationals, Brendan Kuty of The Athletic reports.

Volpe will receive a second straight day off Monday in what's viewed as a "reset," per Boone, rather than any indication that Volpe's standing as the team's starting shortstop might be in danger. The 24-year-old is slashing only .169/.213/.338 in August and has taken a step back defensively this season, but the Yankees aren't ready to bench Volpe on a long-term basis. Jose Caballero will get another start in Volpe's stead Monday.

Winn (knee) will start at shortstop and bat second in Monday's game versus the Pirates.

Winn missed Sunday's 7-2 loss to the Rays and underwent an MRI earlier Monday while he manages nagging soreness in his left knee. The imaging revealed improvement in the condition of the knee from a previous MRI, according to Katie Woo of The Athletic, and Winn will continue to manage the issue on a day-to-day basis based on pain tolerance.

Adames went 2-for-3 with two walks and a stolen base in Sunday's 4-3 win over the Brewers.

Adames singled to center field in the sixth and subsequently stole second base. The shortstop added another single in the eighth, marking his second multi-hit performance in the Giants' three-game series in Milwaukee. Adames' recent success is an encouraging sign, as he has struggled to stay consistent throughout August, slashing .160/.269/.383 with 13 runs scored, eight RBI, six homers, three stolen bases and a 30.1 percent strikeout rate across 93 plate appearances in 21 games.

Bichette went 2-for-3 with a walk, a double and a run scored in Sunday's loss to the Marlins.

The shortstop extended his hitting streak to nine games with the performance, a stretch in which he's batting a sizzling .444 (16-for-36) with five doubles, five RBI and eight runs. Bichette hasn't homered since Aug. 6 and hasn't stolen a base since May 4, but he's racked up plenty of fantasy value all the same, leading the majors with 164 hits while compiling a .304/.348/.471 slash line over 128 contests with 16 home runs, four steals, 70 runs and 83 RBI.

Winn will undergo an MRI on his injured left knee Monday, John Denton of MLB.com reports.

Winn has been playing through soreness in the knee since around the All-Star break and was scratched from the lineup ahead of Sunday's 7-2 loss to the Rays due to renewed discomfort. He underwent an MRI in July which "showed a little something," per Winn, and he'll have imaging on the knee again Monday. The shortstop hopes to return to the lineup for Monday's game against the Pirates, but more will be known regarding Winn's condition after the MRI results are in. If Winn has to miss additional time, Thomas Saggese would likely handle the bulk of the reps at shortstop for the Cardinals.
