Peguero went 1-for-4 with a solo home run and a walk in Saturday's 8-4 win over Atlanta.

Peguero has gone 8-for-30 (.267) with two extra-base hits over eight games in September, though he is maintaining consistent playing time in the middle infield. The rookie is slashing .252/.301/.437 with seven homers, 22 RBI, 19 runs scored and four stolen bases over 42 contests this season. Peguero will likely continue to split time between second base and shortstop, with Alika Williams and Vinny Capra also mixing in on occasion.

Westburg was removed from Saturday's game versus the Red Sox with an undisclosed injury, Danielle Allentuck of TheBaltimoreBanner.com reports.

Orioles manager Brandon Hyde wouldn't divulge any details on Westburg's injury, only saying that "everyone has little things" they're dealing with at this point of the season. The skipper did say he hopes Westburg will be available to play Sunday, so whatever the rookie is dealing with doesn't seem to be a big concern. Westburg went 3-for-4 with a solo home run before exiting Saturday's contest, falling a triple shy of the cycle.

Estrada (illness) is starting at second base and batting second Saturday against Colorado, sSusan Slusser of the San Francisco Chronicle reports.

Estrada was a late scratch from Friday's lineup after suffering from a case of pink eye, but it no longer seems to be a problem heading into Saturday's game. The 27-year-old is slashing just .250/.280/.292 across 25 plate appearances since Sept. 1.

Rengifo was placed on the 10-day injured list Saturday with a biceps tendon rupture, an injury which is expected to be season-ending, Sam Blum of The Athletic reports.

The injury is poorly timed for Rengifo, who was on a tear at the plate. In his last 16 games, he slashed .443/.471/.770 with five homers. He'll finish the season with a .264/.339/.444 line, an improvement on his .264/.294/.429 performance from a year prior.

Rodgers isn't in the Rockies' lineup Saturday against the Giants.

Rodgers will get a breather after going 5-for-20 with an RBI and three runs scored across his last five games. Harold Castro will fill in as the Rockies' second baseman and bat eighth.

Marte left Saturday's game against the Cubs in the seventh inning due to right knee soreness.

After fouling a ball off his right knee in the first inning, Marte's injury caught up to him in the seventh, and he was replaced at second base by Geraldo Perdomo. Marte's injury wouldn't seem to be too severe given he remained in the game for a prolonged stretch after the initial incident.

Diaz will be on the bench for Saturday's game against the Rangers.

Diaz's .239/.294/.403 slash line in 75 games this season isn't particularly impressive, and he's gone just 3-for-19 at the plate across his last six games. Kevin Smith will take over at the hot corner Saturday.

Marte was removed from Saturday's game against the Cubs in the seventh inning, Theo Mackie of The Arizona Republic reports.

Marte fouled a ball off his right knee in the first inning of Saturday's contest, but he was able to stay in for another six innings afterward. The fact Marte was able to remain in the game for so long likely means he's not seriously injured, but the D-backs will surely keep an eye on him. Marte should be considered day-to-day for now.

Short (forearm) will bat ninth and play shortstop Saturday against the White Sox.

Short hadn't seen the field since getting hit by a pitch Wednesday against the Yankees, though he doesn't have an everyday role at the moment, so his absence may not have been injury-related. He hasn't done much to stake a claim for more at-bats down the stretch, posting a .442 OPS in the last month and a .645 OPS on the year.

Frazier will sit Saturday against southpaw Chris Sale and the Red Sox.

Frazier has filled a strict platoon role in the second half, as the only two lefties he's started against have been openers. The Orioles have shifted Jordan Westburg to second base and inserted Jorge Mateo at shortstop against most southpaws over the last few months, and they'll go with the same setup Saturday.
