KANSAS CITY, Mo. -- The Chicago White Sox became the first team to follow consecutive 100-loss seasons by reaching the playoffs on Thursday, throttling the Kansas City Royals 9-1 to ensure no worse than one of the three American League wild-card spots for the postseason.
They could still win the AL Central, too. The White Sox began the day one game behind the Cleveland Guardians.
Chicago has three games left at home against the last-place Colorado Rockies, while the Guardians wrap up their series in Boston on Thursday night before flying to Kansas City, where they coincidentally have three left against the Royals.
Thursday's victory by the White Sox mathematically eliminated Baltimore from postseason contention.
Across town, the Cubs also clinched a playoff berth, marking the first time that the two longtime franchises wrapped up a postseason beth on the same day -- and only the fourth time that both have advanced in the same season.
Kyle Teel homered and reached base five times, and five different White Sox drove in runs. David Sandlin (3-2) allowed one run on five hits over six innings against the club that drafted him out of Oklahoma four years ago.
Randy Dobnak (3-5) allowed six runs -- four earned -- for Kansas City. He also made two errors while retiring just four batters.
Salvador Perez homered for the Royals, reaching 20 in a season for a club-record 10th time.
The first couple of innings summed up what the White Sox have done so masterfully this season: They capitalized on mistakes.
Sam Antonacci opened the game with a single, Teel reached on a bunt when Dobnak's throw was wide of first base, and Miguel Vargas followed with an RBI single. Andrew Benintendi added a sacrifice fly and, after Vargas stole second to get into scoring position, Tristan Peters brought him home with another single to make it 3-0.
More hijinks ensued in the second: Braden Montgomery singled leading off, Dobnak walked Antonacci, then the right-hander threw to nobody covering first base for his second error. That allowed Montgomery to easily score from second.
By the time Dobnak plunked Teel and Vargas added another RBI single, the champagne was probably on ice in the clubhouse.
The White Sox improved to 82-77, a record number of wins for a club coming off three straight 100-loss years. They head home having won four of their last five with their first playoff appearance since 2021 in their pocket and a division title still in their sights.
Not all went according to plan for Chicago, however. Colson Montgomery struck out for the 223rd time this season, tying the season record set by Arizona's Mark Reynolds in 2009.
The 24-year-old Montgomery began the day tied for second on the dubious list with former White Sox slugger Adam Dunn.
