The Yankees rolled. Then they sputtered. The trade deadline could decide their final phase

It is not really breaking news that you can split the Yankees’ season into two distinct parts — before and after June 15.

The Yankees went 50-22 over their first 72 games. Then they went 10-23 over the next 33 games, before winning a pair in Boston over the weekend to earn just their second series victory in six weeks and adding a resounding 14-4 win Monday night over the MLB-best Phillies.

So, heading into Tuesday’s trade deadline off a couple of days that counted as the most encouraging stretch the team has had in a minute, what with the convincing wins combined with a deal to bring in Jazz Chisholm Jr., the question is whether the third stage of the marathon started at Fenway Park.

There is still quite a lot to play out between now and 6 p.m. ET on Tuesday.
