What happened: Luis Arraez fouled a ball off his foot in the first inning of Tuesday's series opener against the Athletics, taking the ricochet off his bat near the arch despite wearing a shin guard. The Giants' second baseman finished the at-bat with a noticeable limp and stayed in through an additional knock before exiting in the fifth, with Casey Schmitt sliding over to second. Manager Tony Vitello said X-rays came back clean and that Arraez, only "a little sore," is considered day-to-day.

Why it matters: The timing magnifies the stakes: Arraez is San Francisco's top trade chip with roughly a month until the August 3 deadline, and the Giants sit well below .500 as obvious sellers. A three-time batting champ on a one-year deal who has also been a revelation defensively at second, he projects to fetch a larger prospect return than higher-paid names like Matt Chapman, Willy Adames or Rafael Devers. A fracture would have gutted that value before the front office could cash in.

What to watch: The Giants will reassess the swelling Wednesday morning to determine availability; Vitello said "if he can go, he'll go." Watch whether Arraez returns to the lineup or the team plays it cautious to protect his deadline value.
