The American League record is 21 by the Orioles in 1988, the Major League record is 23 by the Phillies in '61 and 10 franchises -- the Athletics, Braves, Nationals/Expos, Orioles, Phillies, Red Sox, Reds, Royals, Tigers and Twins -- have dropped more than 17 straight games in a season since '01.
With that, here are the longest single-season losing streaks for every club over the past 110 years:
Angels: 11 (1974, '92, '99): Not surprising, all three of those seasons were 90-loss campaigns for the Halos, who finished 68-94 in '74, 72-90 in '92 and 70-92 in '99.
Astros: 11 (1995): Those Terry Collins-led Astros had three 10-game winners on their staff -- Doug Drabek, Shane Reynolds and Greg Swindell -- got solid seasons from Craig Biggio and Jeff Bagwell, and finished second in the National League Central.
Athletics: 20 (1916, '43): By the time the '16 streak finished, the A's had dropped 56 of 60 games to finish the season 36-117; they finished with 105 losses under Connie Mack in '43.
Blue Jays: 12 (1981): Toronto finished that split season 37-69 under Bobby Mattick.
Braves: 19 (1906): This wasn't a good year to be a Boston baseball fan, as both clubs -- the Braves and Red Sox, then known as the Beaneaters and Americans, respectively -- had losing streaks of at least 19 games and lost at least 100 contests.
Brewers: 14 (1994): Under Phil Garner, Milwaukee finished that strike-shortened season 53-62.
Cardinals: 15 (1909): Fred Beebe went 15-21 with a 2.82 ERA in 44 games (34 starts), but still the 1909 Cardinals finished 54-98 under Roger Bresnahan.
Cubs: 14 (1997): The Cubs lost their last two games of the '96 season, then started '97 0-14 under Jim Riggleman.
Diamondbacks: 14 (2004): With their World Series magic from three years earlier a distant memory, the '04 D-backs dropped a franchise-record 111 games and dismissed skipper Bob Brenly after 79 of them.
Dodgers: 16 (1944): Then in Brooklyn, N.Y., the Dodgers finished 63-91 despite a .357 batting average from Dixie Walker.
Giants: 13 (1944): The Giants, meanwhile, had Mel Ott as a player-manager and finished 67-87 despite a spectacular 21-win season from Bill Voiselle.
Indians: 12 (1931): The Indians finished two games above .500, got a combined 61 wins from four of their starters and received a .979 OPS from Earl Averill.
Mariners: 17 (2011): The Mariners started the losing streak at .500 and just 2 1/2 games out of first place.
Marlins: 11 (1998 twice, 2011): Florida's '11 streak came during a five-win June; the two from '98 came one year after the franchise's first World Series championship.
Mets: 17 (1962): It was the Mets' expansion year, and a brutal one under Casey Stengel; they finished with 120 losses.
Nats/Expos: 20 (1969): Yet another expansion year for a franchise, '69 saw the Mets shock the world with a World Series title, and saw the first-year Montreal Expos finish with 110 defeats.
Orioles: 21 (1988): The O's began that season 0-21, and Cal Ripken Sr. was let go as manager only six games in.
Padres: 13 (1994): A .394 batting average from Tony Gwynn wasn't enough for San Diego to find success during that strike-shortened campaign.
Phillies: 23 (1961): In a season that saw them set the record for longest losing streak, the Phills finished 47-107 under Gene Mauch.
Pirates: 13 (2006): These are better days for the Buccos, but this losing streak came in Year 2 of six in a row in which Pittsburgh lost at least 90 games.
Rangers: 15 (1972): With Hall of Famer Ted Williams as its manager, Texas finished 54-100 in '72.
Rays: 15 (2002): In '02, their fifth year of existence, the Rays went 55-106 and were knee deep in a run of 10 straight 90-loss seasons to start their franchise's history.
Red Sox: 20 (1906): This '06 team -- then named the Boston Americans -- dismissed skipper Jimmy Collins after 114 games and finished the year 49-105 under Chick Stahl.
Reds: 19 (1914): This Cincinnati team, under Buck Herzog, finished 60-94 and had four losing streaks of at least five games.
Rockies: 13 (1993): The Rockies' expansion year wasn't a great one -- they finished 67-95 under Don Baylor -- but they made the playoffs in 1995.
Royals: 19 (2005): In a season that saw them establish the longest losing streak of divisional play, the Royals dropped 106 games while getting a 5-17 record and a 5.80 ERA from Zack Greinke.
Tigers: 19 (1975): This Ralph Houk-led Tigers team finished 57-102.
Twins: 18 (1948, '59): They were then known as the Washington Senators, and they went 56-97 in '48 and 63-91 in '59.
White Sox: 13 (1924): Five years removed from the Black Sox scandal, the '24 White Sox finished 66-87 and in last place in the AL.
Yankees: 13 (1913): This was the first year they had formally taken on the name "Yankees," and they finished 57-94. There would be better days.
