On deck: Yankees-Rays battle for AL East lead, Giants, Cardinals face litmus test

The final week before Major League Baseball's All-Star Game break could provide answers that will settle standings at the top and bottom of several divisions.

Yankees-Rays set for center stage

A four-game series at Tropicana Field could provide a glimpse into just how aggressive the New York Yankees and Tampa Bay Rays could be at the upcoming MLB trade deadline.

With the series beginning on Monday night, the Rays lead the American League East by 4.0 games over the Yankees. On the final Monday of June, that lead was just 1.5 games. However, the Yankees have gone 1-9 over their last 10 games while Tampa Bay has gone 8-2.

Tampa Bay is already 4-1 this season against the Yankees, including sweeping New York in a three-game home series in mid-April. However, every game was close, with the Rays winning the series by a total of just four runs.

There is little doubt that the Yankees will be active at the MLB trade deadline. However, just how far they find themselves back in the division after this series could determine not only the level of aggressiveness going after potential trade chips, but also the level of panic there could be in doing so.

Will the St. Louis Cardinals keep proving they're for real?

The Milwaukee Brewers have a 7.5-game advantage over the St. Louis Cardinals in the National League Central standings. However, the Cardinals have a golden opportunity this week to cut into that lead and show they will be a team to watch in the second half.

St. Louis is 1-4 against Milwaukee so far this season, but the Cardinals will host the Brewers for five games this week, including a Tuesday doubleheader. It's a good time for the Cardinals to face a division foe as, before Sunday's 6-4 loss to the Chicago Cubs, St. Louis had won six straight against NL Central opponents, marking its longest intradivisional winning streak since taking 11 consecutive games in 2021.

According to FanGraphs, St. Louis had a 42.5 percent chance to make the postseason heading into Sunday. Compare that to April 1's 10.7 percent chance, and you can see how the Cardinals have surprised this season. St. Louis could add to that surprise this week with a strong showing against the Brewers.

Are the San Francisco Giants heading for the NL West cellar?

The bottom of the NL West has belonged to the Colorado Rockies for the majority of the past four seasons. However, the San Francisco Giants are in danger of falling to the bottom of the division this week.

San Francisco dropped two of three games to the Rockies over the weekend at Coors Field, shaving its lead over Colorado at the bottom of the NL West standings to just one game. Now, the Giants face a big week to see if they can avoid what could be a big talking point heading into the All-Star Game.

The Giants will host the Toronto Blue Jays for three games before welcoming the Rockies for the final four games of the unofficial first half. Those are seven games that could carry a lot of weight for a Giants team that has had a nightmarish few weeks on and off the diamond.

Yes, Colorado has three games at Chavez Ravine against the Los Angeles Dodgers before heading to San Francisco. However, the Rockies could walk into Oracle Park with a chance to climb over San Francisco. Will that be the icing on a horrific cake of a 2026 season so far for the Giants?
