Ivan Herrera’s recent dip at the plate doesn’t look like a reason for panic, but it does look like a reason for the Cardinals to think about giving him a breather.
Herrera has been in the lineup every day this season, and that alone makes his workload stand out. He has never played more than 107 big league games or 99 minor league games, so the fact that he’s already at 87-for-87 is a big deal. It’s even more notable when you consider that 38% of those games have come behind the plate.
That kind of grind may be catching up with him. Since the final game of the Minnesota Twins series on June 14, Herrera is hitting .200/.366/.262 with only two extra-base hits over his last 82 plate appearances.
For most hitters, that would be a real problem. For Herrera, who is one of the best in baseball at finding ways on base, it’s more of a slowdown than a collapse.
He’s still only 5% below league average over that stretch, and his .366 on-base percentage is doing a lot of the heavy lifting.
But when Herrera is rolling, he gives the Cardinals something more dangerous than just traffic on the bases. He can produce 30%-40% above league average and lift the lineup to another level. With five games against the Milwaukee Brewers this week and three against the Atlanta Braves before the All-Star Break, the Cardinals would love to get that version of him back quickly.
The underlying numbers back up the idea that something has changed. One of the biggest red flags is his FastSwing%, which tracks how often Herrera swings at 75 MPH or harder.
That matters because hitters usually do more damage when they get into that zone. Since June 16, Herrera’s FastSwing% has dropped to 35.5%.
Earlier, his 45.3% FastSwing% ranked 41st among 156 hitters, but that latest mark has slipped him to 62nd.
The decline doesn’t stop there. Over this stretch, Herrera has also seen a 5.2% drop in both his HardHit% and Barrel%, nearly a 3% drop in his Blast%, and his infield fly ball rate has nearly doubled from 13.3% to 26.1%.
The All-Star Break is right around the corner, and that should give Herrera a chance to reset. Even so, a few off days in the second half would make sense. Herrera clearly takes pride in being out there every day, but if the workload is starting to chip away at his production, the Cardinals may be better off giving him a little more rest.

Ivan Herrera Found A Wild Way To Solve The Brewers' Flame Thrower
Facing a Brewers pitcher who has been piling up strikeouts at the top of the league, Ivn Herrera had to get creative before first pitch. The Cardinals slugger spent pregame work on a pitching machine cranked to 107 mph, a deliberate attempt to make Jacob Misiorowskis fastball feel a little less overwhelming once the real thing arrived.
The approach paid off in the moment, as Herrera turned on a Misiorowski pitch and gave St. Louis a temporary edge with a solo shot. It was the kind of at-bat that can change the feel of a game and reinforce why Herrera remains such an intriguing middle-of-the-order piece for the Cardinals, even against one of the sports most electric young arms.

Cardinals Face A Trade Deadline Mistake Fans Know Too Well
With the trade deadline closing in, the Cardinals find themselves in one of those familiar in-between spots, close enough to the race to feel the pull of adding help, but still far enough from finished to remember how fragile that kind of push can be. St. Louis is hanging just behind the third National League wild card spot, which makes the next few days more than a routine checkpoint for a club still trying to turn its rebuild into something more lasting.
Derrick Goold of the St. Louis Post-Dispatch has argued the Cardinals should not simply sit on their hands and hope the standings sort themselves out. Instead, the front office may need to choose a path that reflects both the present and the future, whether that means buying, selling, or finding a way to do both at once. For a team trying to become a legitimate contender again, the danger is not just making the wrong move, but making none at all. [Read more 🡒]
Cardinals Are Running Out Of Reasons To Keep Quinn Mathews Waiting
Quinn Mathews has spent 2026 making a much stronger case for himself after a rough 2025, and the Cardinals have to be paying attention. The left-hander has cleaned up enough of the mess from last season to move into the conversation for a major league promotion later this year, giving St. Louis a young arm worth tracking as the roster picture starts to tighten.
The timing still feels like the real question. The Cardinals may be waiting for the trade deadline to pass before making any move, when a little more roster flexibility could open up, and Mathews could be the kind of pitcher who forces the issue once that window arrives. Whether his first look comes in a short-term role or as part of a more direct path to the rotation, the organization is getting closer to a decision it can keep putting off only so long. [Read more 🡒]
