An important night for the Twins as they face Cincinnati (6:10 p.m., FSN) in the penultimate game of the regular season at Target Field.

The Twins can clinch the American League Central Division title with a win and a White Sox loss to the Cubs. A win by the Twins under any circumstances means they would clinch home field for the first round of the playoffs; if the Twins win, White Sox lose and Oakland sweeps Seattle, the Twins would be locked in at the No. 3 seed.

Second baseman Luis Arraez was reinstated from the injured list, and reliever Devin Smeltzer was promoted from the St. Paul group. Edwar Colina, who had a rough MLB debut Friday, and utilityman LaMonte Wade were optioned.

Arraez missed the past 14 games because of knee and ankle injuries.

Cincinnati clinched its spot in the playoffs with Friday's 7-2 win at Target Field. It was a costly loss for the Twins as Josh Donaldson left with a calf cramp and Byron Buxton was beaned, leaving because of a head contusion.

Twins President of Baseball Operations Derek Falvey said Donaldson, who was on the IL earlier this season because of a calf issue, was feeling better today. Buxton had mild concussion symptoms (soreness, headaches) and will be reassessed tomorrow. Falvey was confident Buxton would be ready for Tuesday's playoff opener.

Reusse wrote about the losing pitcher, Jose Berrios, and his importance to the Twins in the playoffs.

Michael Pineda (2-0, 3.18 ERA) pitches for the Twins against Luis Castillo (4-5, 2.86). After clinching, the Reds announced Trevor Bauer will pitch Game 1 of the playoffs and Sonny Gray will start tomorrow against Twins lefty Rich Hill. The Reds playoff rotation will be Bauer, Castillo and Gray for a series that starts Wednesday.

The Twins playoff rotation is Kenta Maeda on Tuesday, Berrios on Wednesday and, if there's a Game 3, Pineda on Thursday.

The Twins can clinch a home playoff berth tonight if they beat the Reds at Target Field (7:10 p.m., FSN).

Playoff scenarios are complicated, we know. The first-place Twins have a one-game lead in the American League Central Division over the White Sox and two over Cleveland with three games remaining.

But their magic number to clinch at least the No. 4 seed in the eight-team playoffs -- and the right to host the best-of-three Wild Card Series at Target Field on Tuesday, Wednesday and (if needed) Thursday -- is one.

Jose Berrios (5-3, 3.72 ERA and pictured) pitches for the Twins vs. righthander Tyler Mahle (2-2, 3.57) for the Reds.

The Twins designated starting pitcher Homer Bailey for assignment or release before the game and promoted pitcher Edwar Colina from the St. Paul site. Colina, 23, has yet to pitch in a major league game.

Bailey pitched in two games this season, both starts, but spent almost all the season on the injured list because of a biceps strain. He was 1-0 with a 3.38 ERA. He signed an incentive-laden one-year contract with the Twins last offseason.

The Twins-Reds series preview is here.

Longtime Cincinnati broadcaster Thom Brennaman resigned today.

Nelson Cruz (knee) is back in the Twins lineup after missing the past four games.
