Vientos went 3-for-4 with a run, one RBI and a stolen base in Sunday's 8-4 win over the Reds.

Vientos knocked an RBI single and swiped second base in the fifth inning and later scored a run in the seventh. It was the first three-hit game of his MLB career and his third multi-hit performance this month. Vientos is slashing .218/.262/.345 with 16 RBI through 187 plate appearances on the year, but he's gone 15-for-50 (.300) over his last 14 games.

Choi is out of the lineup for Sunday's game against the Athletics.

Choi was reinstated from the 10-day injured list Friday, but he'll end up starting just one of the three games in the series since Oakland is using a pair of lefties, including Ken Waldichuk as the bulk pitcher Sunday. Manny Machado will serve as the designated hitter while Eguy Rosario starts at the hot corner.

Soler (oblique) was activated from the 10-day injured list and is batting second as Miami's designated hitter Sunday against Atlanta, Jordan McPherson of the Miami Herald reports.

Soler landed on the shelf Sept. 6 with an oblique strain -- after he missed the previous five games with a hip issue -- but he'll rejoin the active roster following a quick stay on the IL. The veteran slugger is hitting just .231 in 25 games since the start of August, though he's still showcased his power during that stretch with 10 homers.

Pederson will be on the bench for the second game of Saturday's doubleheader against the Rockies, Susan Slusser of the San Francisco Chronicle reports.

Pederson went 0-for-4 with a pair of strikeouts in the afternoon game. He'll hit the bench for the nightcap with lefty Kyle Freeland starting for Colorado. Luis Matos starts in left field, while Mike Yastrzemski serves as the designated hitter.

Blackmon will be on the bench for the first half of Saturday's doubleheader against the Giants, Patrick Lyons of TheDNVR.com reports.

The veteran outfielder will unsurprisingly not be asked to start two games on one day. Hunter Goodman will handle right field in the afternoon game, but Blackmon could return to the lineup for the nightcap.

Morel went 2-for-4 with a solo home run in Friday's 6-4 loss to the Diamondbacks.

Morel has homered four times over his last eight games, adding seven RBI in that span. The 24-year-old's gotten back into form over the last week or so, which has in turn helped him stay in the lineup more regularly, though the Cubs have also faced southpaws in three of their last five games. For the year, Morel is slashing .248/.312/.504 with 23 homers, 67 RBI, 55 runs scored and four stolen bases over 96 games.

Harper was ejected from Friday's game against the Cardinals, John Denton of MLB.com reports.

Harper was upset by a called second strike that looked to be high and out of the strike zone. He struck out swinging on the next pitch and after firing his bat and helmet toward the third-base dugout, directed comments in the general vicinity of home plate umpire Alex Tosi that got him tossed. Harper had gone 0-for-2 with a run and an RBI prior to the ejection.

Pederson isn't in the Giants' lineup Friday against Colorado, Evan Webeck of The San Jose Mercury News reports.

After going 5-for-19 with a home run, three RBI and four runs scored across his last six games, Pederson will get a breather for Friday's series opener. Mike Yastrzemski, Luis Matos and Mitch Haniger will start across the outfield while Michael Conforto serves as the Giants' DH.

The Padres reinstated Choi (ankle) from the 10-day injured list Friday.

Choi initially landed on the injured list Aug. 14 due to a left rib strain, but his stay was extended after he suffered a fractured ankle during a rehab game at Triple-A El Paso. Fortunately for the Padres, Choi was cleared to resume playing relatively quickly, and he will return to San Diego after going 4-for-25 with an RBI and a run scored through seven rehab games. Matt Carpenter (elbow) was placed on the 10-day IL in a corresponding move.

The Padres placed Carpenter on the 10-day injured list Friday with right elbow inflammation.

The move comes retroactive to Tuesday, so Carpenter will be eligible to return in a week. Carpenter has gone 2-for-10 with a homer, two RBI and two runs scored since the start of September, and he will be replaced on the roster by Ji-Man Choi (ankle), who was reinstated from the injured list Friday.
