With the MLB regular season nearly at the midway point, there has been a betting pivot thanks to a hot streak by the Yankees and a slump by the Astros, which had long been the favorites in the American League. Having won nine of ten ahead of Tuesday's game against the Blue Jays, New York is the new favorite at multiple sportsbooks to win the AL pennant. The Yankees are listed at +175 at the Westgate SuperBook in Las Vegas, adjusted from +300 (3/1 odds) last Monday, while Houston's price was lengthened from +160 a week ago to +225. The Yankees, who on Monday tied an MLB record with home runs in [27 straight games](https://www.northjersey.com/story/sports/mlb/yankees/2019/06/24/new-york-yankees-tie-mlb-record-home-run-27th-straight-game/1551950001/), are now the 4/1 second favorites to win the 2019 World Series, behind the 3/1 Dodgers and ahead of the Astros at 9/2 (+450). The Yanks were 6/1 a week ago. __Update__: The Yanks made it 10 of 11 with Tuesday'S 4-3 win over Toronto and broke the record by homering in their 28th consecutive game. In fact, they hit [four solo shots](https://nypost.com/2019/06/25/yankees-break-a-home-run-record-in-spectacular-fashion/). Houston's 9-4 win over the Yankees on Sunday [snapped a seven-game losing streak](https://www.espn.com/mlb/recap?gameId=401075896). New York took three of four in the weekend series. The Westgate’s Randy Blum explained in an email to BetChicago on Tuesday the reason for the adjustment. > “We view the two teams as being equal. Both are starting to get their injured players back,” Blum wrote. “We do have some small liability on the Yankees right now. We are in a very good position on the Astros. With the Astros recent slide they are no longer considered the favorite to have home field in the playoffs. Combine all that together and we decided to go with the Yankees as the favorite. The next few weeks will really determine the favorite though. We will get to see how each team looks with their full roster. Or close to full.” Tuesday morning, Caesars had both the Yankees and Astros priced at 2/1 to win the pennant. Jeff Davis, director of trading at Caesars, wrote in an email to BetChicago the adjustment was a matter of “recency bias.” “(There is) better potential for NYY after recent run of play,” Davis explained. With the trio of favorites separating themselves on the oddsboard, Caesars posted a World Series bet pitting the Dodgers, Yankees and Astros against the field. The 'yes' side of the 'Will the Yankees, Dodgers or Astros win the World Series' prop is priced at -165, with the 'no' offered as the +145 underdog.
