Casey Schmitt’s knee injury scrambles Giants’ plans with trade deadline approaching

SAN FRANCISCO — It doesn’t matter where a team resides in the standings. The trade deadline creates anticipation in every major-league clubhouse.

That anticipation comes in different flavors. For contending teams, the mood is pretty straightforward: the hopeful giddiness of a fourth grader on Christmas Eve, wondering what infusions of talent will await them under the tree.

For also-rans like the San Francisco Giants, it’s a little more complicated. The players most likely to be dealt, primarily the impending free agents, can look forward to a 20-game jump in the standings and the prospect of playing meaningful baseball again while platforming themselves for another contract — even if decorum requires they keep their eagerness under wraps. The players less likely to be traded, either because they are inexpensive or underperforming, have their guard up as well because they know anything can happen.

Then there are players like Giants outfielder Grant McCray, who are equipped with a wealth of tools and a wellspring of confidence and feel they only need a stretch of runway in the big leagues to take off. If the trade deadline takes one player out of the Giants’ orbit, perhaps that’ll change the weather patterns — and the opportunities — for everyone else.

But the trade deadline isn’t the only catalyst for change. There are all the standard wobbles in a 162-game season that can happen at any moment, and as Casey Schmitt experienced Monday night, some of them are crueler than others.

Schmitt slammed on the brakes around first base and grabbed at his left knee after reaching on a bloop single in the second inning of the Giants’ 3-0 victory over the Milwaukee Brewers. He was in too much discomfort to attempt to stay in the game and limped off the field, replaced by pinch runner Christian Koss.

The Giants provided no preliminary diagnosis and manager Tony Vitello painted a disjointed picture of Schmitt’s outlook, initially saying only that Schmitt wouldn’t play on Tuesday and, a bit later, acknowledging that the power-hitting infielder “is probably going to miss some significant time.”

The team will know more after Schmitt, who appeared to hyperextend his left knee, goes for an MRI Tuesday. In all likelihood, Schmitt is headed to the injured list, interrupting what’s been a breakout season that had him on pace for 32 home runs and 85 RBIs and likely would’ve won him incumbent status as an everyday player next spring.

That’s because there’s every expectation the Giants will trade Luis Arraez, whose impending free agency almost certainly overrides his .326 average, team-leading 3.2 bWAR and the feisty joy with which he plays and has made him a fan favorite.

The Giants have bounced Schmitt all over the diamond this season to keep his bat in the lineup. They even started him in the outfield, where he hadn’t played since wearing a blue Eastlake High Titans jersey in Chula Vista, Calif. If Giants president Buster Posey has spent any time thinking about how he’d console fans over trading Arraez, then selling the upside of Schmitt as the everyday second baseman would be a good place to start.

Now the Giants have a bunch of new stuff to think about. Assuming Schmitt goes on the IL, who replaces him on the roster? And assuming Arraez is traded before Monday’s deadline, who plays second base the rest of the way?

One other potential question now appears moot: Should the Giants sell high on Schmitt and try to flip him for some pitching?

Schmitt has been playing third base over the past four weeks while Matt Chapman was on the IL with an abdominal strain, and although Chapman is nearing the end of his rehab schedule, Vitello said the five-time Gold Glove third baseman needed more time and wasn’t likely to be activated on Tuesday.

“Almost a certainty (a roster move) would involve somebody else rather than rush things (with Chapman) and have something else pop up,” Vitello said.

Here’s the thing: The Giants don’t have any other healthy minor-league position players on the 40-man roster. They do have two roster vacancies, though. (Can you imagine former Giants president and waiver-wire enthusiast Farhan Zaidi considering that anything other than an affront?)

So power-hitting corner infielder Parks Harber, who was batting .415 in nine games since moving up from Double-A Richmond to Triple-A Sacramento, is one possibility. The Giants would need to place Harber on the 40-man roster this winter anyway to shield him from being taken in the Rule 5 draft. Nate Furman, Jake Holton and Turner Hill are other possibilities.

And if Schmitt ends up missing several weeks or more? Well, Jonah Cox is nearly recovered from his oblique injury and could merit a longer look. But the player who might stand to benefit most is Jesus Rodríguez, whose opportunities have been limited to spots off the bench and rare starts as the third catcher on the roster.

Rodríguez drew one of those assignments behind the plate Monday night, hit a leadoff double in the third inning, and scored on Arraez’s single. Rodríguez also drew raves from right-hander Tyler Mahle for his game-calling skills.

McCray did the rest. Given some of that runway over the past week, the 25-year-old left-handed hitting outfielder has been putting his entire game on display.

McCray launched a two-run home run that traveled 408 feet and landed comfortably in the left-center field bleachers in the fourth inning, which was all the support Mahle and three relievers needed as the Giants opened a home series against the NL Central leaders with one of their tidier victories on the shores of McCovey Cove.

“I’ve just been able to get at-bats, and really, that’s been the main thing,” McCray said. “I know I can change the game offensively and defensively, so being able to get to show that side has been awesome.”

It’s fair to wonder why McCray had to wait this long. He did everything the Giants asked of him in spring exhibition games, working counts and drawing walks while cutting down on what had been an indefensibly high strikeout rate. McCray also plays with a fearlessness that appeared perfectly in step with the environment that Posey hoped to create when he hired Vitello, who led a rollicking University of Tennessee program to a College World Series title in 2024.

“In the last seven days, he’s shown you everything he can do, whether it’s stealing a base in an important situation, throwing runners out, playing hard up until the last moment, and if you count the Seattle (series), making a couple really nice catches in the outfield,” Vitello said. “And now he’s got some at-bats and seen some live pitching under his belt. Getting to see him use that swing, it’s got a lot of whip to it, and the numbers or the results kind of speak to itself.

“He provides something we could use a little more of, everybody could, is a little attitude to it, too.”

What McCray wasn’t provided was a place on the opening day roster. The Giants optioned him well before their last rounds of cuts in Arizona. Sometimes it takes a whole lot of wobbles from the baseball universe to correct a mistake.

On balance, the Giants’ $10 million investment in Mahle wasn’t their soundest decision, either. He was 1-7 with a 6.04 ERA in 11 starts before hitting the IL with a strained hamstring at the end of May, and the Giants were essentially cooked by the time he returned.

There’s still time to rescue some value from that contract, though. Mahle has looked awfully good over his last three starts, flashing a mid-90s fastball and regaining late life on his splitter while holding opponents to four runs over 18 innings. He faced one more than the minimum over six innings while containing one of the NL’s highest-scoring lineups, using his splitter to induce three double-play grounders.

All along, the assumption has been that left-hander Robbie Ray, the 2021 AL Cy Young Award winner and an All-Star last season, would be the rental pitcher who could fetch the Giants something of value at the trade deadline. But Ray is owed roughly $8 million the rest of the way. Mahle is owed closer to $3 million, and even if their salaries were cash neutral, he might be pitching well enough to be the preferred choice for some teams.

The Giants, of course, can and should throw in as much cash as necessary with either starting pitcher to extract the maximum talent from an acquiring team. If there’s sufficient interest, the Giants could have two vacancies in their rotation by the middle of their next road trip. Combined with the loss of right-hander Trevor McDonald, whose season is almost certainly over because of a partially torn ulnar collateral ligament, the Giants could have a whole mess of innings to fill in August and September.

Here’s another baseball truism that applies universally: Shortages create opportunities.
