KANSAS CITY — On the surface, it was just a lineup card. Aaron Boone tweaked his infield for one game in Kansas City. The Yankees won, and most fans moved on.
But the small change carried a big message. It may mark the slow goodbye to a player the Yankees once counted on.
A matchup move leaves $70m bat on the bench
The setup looked simple enough. Jose Caballero shifted to third base. Anthony Volpe returned to shortstop. The Yankees beat the Royals 4-3 on Memorial Day.
One name was missing from the card. Ryan McMahon, the regular third baseman, sat on the bench. He watched a right-hander start while he stayed out of the lineup.
That detail mattered more than it seemed. McMahon is a left-handed hitter. He almost always plays against righties. This time, Boone went another way.
Boone had a clear reason for the move. Royals starter Michael Wacha owns reverse splits. He is tougher on lefties than on righties. So the Yankees manager wanted more right-handed bats in the lineup.
Boone explained the thinking before the game. He framed it as a matchup choice, not a benching. Still, his words hinted at the bigger picture.
“I just wanted to at least have a little bit more of a righty presence today against Wacha, who’s historically tougher on lefties,” Boone said. “But felt like getting another righty bat in there and the athleticism and defense and everything.”
The plan worked to perfection. Volpe delivered the game-winning hit in the ninth. Caballero made a clean play at third to seal it. The new look paid off right away.
Why the shakeup spells trouble for McMahon
Here is the part that should worry McMahon most. For the Yankees, this was not a one-day experiment. It was a glimpse of a future where he sits more often.
The Yankees now have a real choice at third base. Caballero gives them a steady glove and a live bat. He also frees them to play Volpe and Caballero together. That flexibility puts McMahon’s job at risk.
The numbers tell the story behind the Yankees shakeup. McMahon is hitting just .190 this season. His OPS+ sits at a dismal 58. He strikes out far too much and rarely walks.
His broader line is just as ugly. He owns a .187/.253/.306 slash with a 60 wRC+. His strikeout rate sits above 30 percent. He has produced 0.0 WAR through roughly 147 plate appearances.
The bat briefly teased a turnaround. From April 24 through May 7, McMahon slashed .311/.340/.511 with two homers. He was even hotter to start May. For a moment, he looked like the answer.
The surge did not last. Over his last 28 days, McMahon has hit .197 with a .557 OPS. The hot streak now looks like a mirage. The slump has returned with force.
A $70 million contract complicates the exit
The contract makes the situation tricky. McMahon signed a six-year, $70 million deal with Colorado in 2022. The Yankees acquired him last July from the Rockies. They still owe him $16 million in both 2026 and 2027.
That price tag is hard for the Yankees to swallow for a bench bat. New York cannot easily justify paying that for limited at-bats. Yet his production no longer fits an everyday role.
His glove once made the case for the Yankees to keep him. McMahon has long been a reliable defender at third. The Yankees value stability at the position. But the defense alone cannot carry him now.
The fielding has slipped this year, too. McMahon owns a .951 fielding percentage at third base. That ranks as the second-worst rate of his career. His outs above average have dropped as well.
Caballero gives Boone the flexibility he wanted
The Yankees manager has options that did not exist before. Caballero has played 377 innings at third in his career. He logged 41 of them with the Yankees last season. He posted a .980 fielding percentage there with nine double plays.
Caballero embraces whatever role he gets. He has bounced around the diamond for years. He needs only a little pregame work to feel ready anywhere.
The veteran kept his message short and clear. He cares about being in the lineup, not where he plays. His attitude makes the shakeup easier.
“Whenever I’m in there, I’m happy,” Caballero said Monday.
A trade now looms as a real option for the Yankees. The Yankees could target a third baseman before the July deadline. They could also try to move McMahon to a team that believes in a bounce-back.
The Yankees farm offers another path forward. George Lombard Jr. is a 20-year-old infielder with a high ceiling. He could one day take over at third base. Clearing the logjam would help his development.
The timing is far from ideal, though. The Yankees already have other fires to manage. The bullpen, the outfield health, and Aaron Judge’s slump all demand attention. Third base is now another worry.
New York sits at 32-22 on the season. The team holds second place in the American League East. Tampa Bay leads the division by 3.5 games. Every roster choice carries weight in a tight race.
The Volpe-Caballero alignment is not a perfect fix. Both are weaker defenders than McMahon at the hot corner. The trade-off only works if their bats and legs deliver more.
That is the bet Boone is now making. He is choosing offense and athleticism over McMahon’s glove. Monday was the first real sign of that shift. For McMahon, the warning could not be clearer. The everyday job is slipping away. The Yankees have started, quietly, to move on.
What do you think? Is Caballero the right player to replace McMahon?
