The Chicago White Sox’s latest losing streak ended 11 games on Monday with a 13-3 win over the Baltimore Orioles. It was their 20th consecutive loss and put Chris Flexen on track to set the modern baseball record (since 1900) for most consecutive losses by a pitcher in two starts, which he previously shared with Bob Groom of the Washington Nationals.

After a 10-0 home loss, Chicago fell to 31-108, its third-longest losing streak of the season, having lost 21 games from July 10 to August 5 and 14 games from May 22 to June 6. The White Sox would have to go 12-11 to avoid the post-1900 losing record set by the New York Mets in 1962, when they went 40-120.

Chicago is on pace to finish 36-126, which would be second only to the 1899 Cleveland Spiders’ 20-134 record. According to ESPN Stats & Information, the White Sox are 4-41 in their last 45 games, their worst record over a 45-game span since the 1916 Philadelphia Athletics.

Flexen (2-14) allowed three runs and seven hits in 3.5 innings and is 0-11 with a 5.73 ERA in 21 appearances (20 starts) since a May 8 win at Tampa Bay. He broke a tie with Bob Groom of the Washington Nationals for the longest losing streak in starts by a single pitcher since 1900, according to ESPN Stats & Information. The Nationals lost 19 consecutive games started by Groom in 1909. Flexen also has two such losses ahead of Chris Capuano of the Brewers, who was 0-13 with a 6.12 ERA in 23 appearances (18 starts) for Milwaukee from May 13, 2007, to June 3, 2010, missing 2008 and 2009 after Tommy John surgery.

“Every time I have the ball, I expect myself to go out there and be competitive and have strong performances,” Flexen said. “I don’t think many of them were that great, there were a couple of good starts, but overall my performance was very disappointing.”

Cedric Mullins hit a three-RBI home run, and Austin Slater and Gunnar Henderson each scored three runs for Baltimore, which overcame a 2-0 deficit and improved its record against Chicago to 5-0 on the season at the start of a six-game home series.

Henderson opened the first inning with a hit into the right-center stands, tying Cal Ripken Jr. (1991) and Miguel Tejada (2004) for the most home runs (34) by a Baltimore shortstop.

Baltimore’s first hitter reached a run in each of the first six innings for the first time since July 4, 1997, an 11-8 loss at the Detroit Tigers in the second game of a doubleheader. The Orioles struck out 7 of 23 runners in scoring position and moved within one percentage point of the American League East-leading New York Yankees.

The Orioles had their most successful offensive day since scoring a season-high 17 runs on June 20 against the Yankees, and Baltimore’s 18 hits were their most since June 21 against the Houston Astros, when they scored 18.

“I think that’s the offense we believe in and it was fun to see that today,” Slater said.
