Strength of remaining schedule, recent 10-game performance, and projected WAR from newly acquired players were all weighted heavily in this week’s rankings, with teams that addressed clear positional holes seeing the biggest jumps, while teams that stood pat at the deadline mostly slid down the board. The top spot in Week 19 rankings goes to the Baltimore Orioles, who solidified their already formidable roster by adding three-time All-Star starting pitcher Jack Flaherty and left-handed reliever Matt Moore at the deadline, addressing their biggest weak spot of inconsistent late-inning pitching and depth in the back end of their rotation. The Orioles have won 8 of their last 10 games, and their updated roster now gives them the flexibility to match up against any playoff opponent in short series. The Los Angeles Dodgers hold steady at No. 2, after pulling off one of the deadline’s biggest steals by acquiring former Cy Young candidate Shane Bieber from the Cleveland Guardians to pair with Walker Buehler and Yoshinobu Yamamoto in a rotation that now looks unbeatable for postseason play. Their offense, which leads the National League in OPS, already had no obvious gaps, making the Dodgers the clear favorite for the NL pennant as of Week 19. Coming in at No. 4 are the Philadelphia Phillies, who pulled off the highest-profile move of the entire deadline by trading for New York Mets first baseman Pete Alonso, adding another elite power bat to a lineup that already features Bryce Harper and Trea Turner. Alonso has already hit three home runs in his first five games with the Phillies, helping them win four of those contests and extend their lead in the NL East wild card race. The New York Yankees drop three spots to No. 12 this week, after front office leadership declined to make a major addition to their struggling outfield or starting rotation, leaving many analysts questioning whether they have the depth to hold onto their wild card spot amid a brutal remaining schedule that includes 18 games against top-10 ranked teams. For teams on the playoff bubble, the deadline proved to be a clear dividing line between buyers and sellers. The San Francisco Giants, who were just two games out of a wild card spot on deadline day, opted to sell off multiple key relievers and slid 10 spots to No. 22 in this week’s rankings, effectively ending their 2024 postseason hopes. On the flip side, the Seattle Mariners, who many expected to sell, instead added veteran second baseman Ozzie Albies and jumped four spots to No. 7, putting them in prime position to overtake the Houston Astros for the AL West lead in the coming weeks. As teams head into the final 40 games of the regular season, the Week 19 power rankings serve as a critical baseline for measuring postseason odds. Upcoming key series, including the Orioles vs. Rangers, Dodgers vs. Phillies, and Mariners vs. Astros, will likely cause significant shifts in next week’s rankings, as teams test their new rosters against elite competition.
