Red Sox place Marcelo Mayer (forearm) on 10-day IL

Basabe has been shelved since Monday due to tightness in his left hamstring. It’s possible that he could be available off the bench on Sunday. Marcelo Mayer will start at the hot corner for the Giants and will bat cleanup against Jack Dreyer and a host of Dodgers’ relievers.

Mayer will make his San Francisco debut during Monday’s series opener against the Twins at Oracle Park. The 23-year-old former top prospect, who came over from the Red Sox in the Erik Miller swap at the trade deadline last month, has been out nursing forearm and foot injuries since late June. He’s talented enough to be an impactful fantasy contributor at some point in the future, but it simply hasn’t happened at this early juncture of his career. He could benefit exponentially from the change of scenery, but is unlikely to offer much in the final week of the regular season.

It doesn’t sound like Adames will require surgery to address the issue, but he’s headed for a second opinion before that decision is made. It certainly seems like his season is over. The 30-year-old hit the shelf with an elbow sprain earlier this week. It’ll most likely be Christian Koss filling in at shortstop until trade deadline acquisition Marcelo Mayer is ready to return from the injured list.

It’s an injury that also bothered him while Mayer was doing his rehab at Triple-A Sacramento and isn’t expected to keep him shelved for long. He’ll rest for the remainder of the weekend before being evaluated when the Giants return home next week.

Mayer, out since late June with a stress reaction in his forearm, is 5-for-14 with a homer in three games since joining the River Cats. They might wait a few more days, but the Giants will likely activate him this week and install him as their starting second baseman.

Mayer was viewed as one of Boston’s potential future franchise cornerstones just a few years previously. He simply never found his footing at the highest level despite possessing impressive raw talent and a sweet-looking left-handed swing. The 23-year-old former fourth overall selection from the 2021 draft has struggled to stay healthy at the highest level and the Red Sox ultimately decided to move on, using him as a trade chip to fortify their bullpen. The meteoric rise of Franklin Arias, who has emerged as the club’s potential shortstop of the future, seemingly sealed Mayer’s fate here. It’s a decent move for his long-term future as he’ll get a change of scenery and plenty of opportunities to emerge as a key contributor in San Francisco.

The Red Sox sure are burning a lot of talent here. Miller is quite good and under control for three years after this one, but giving up a long-term regular for a left-handed reliever is quite a loss of value. Mayer is currently on the shelf with an arm injury and might not be much of a factor this year, but he should be the Giants’ second baseman next year and he remains very much an option at short if the club could find a taker for Willy Adames. Miller’s fantasy value disappears with the deal, since he won’t be a candidate for saves in Boston. With the Giants shedding both he and Caleb Kilian, Dylan Smith is probably their favorite for saves at the moment.

Mayer landed on the injured list with a stress reaction in his left forearm. He was allegedly playing through the injury for two months, which may have impacted his performance on the field. It may just be a couple of weeks before Mayer could begin a rehab assignment, but his role in Boston for the remainder of the season remains to be seen. The team has been thriving, and they have multiple options in the infield with Romy Gonzalez back and Anthony Seigler and Tsung-Che Cheng providing value. The Red Sox could opt to keep Mayer in Triple-A to get consistent at-bats until rosters expand in September.

Mayer sat out on Thursday due to illness and wasn’t feeling well during the day on Friday, but he felt much better as game time approached and seemingly was able to talk his way into the lineup. He’ll start at shortstop and bat seventh with Isiah Kiner-Falefa heading back to the bench.

It doesn’t sound like Mayer is going to require a trip to the injured list, but he’s still feeling a bit under the weather on Friday. Andruw Monasterio will start at second base and bat ninth for the Red Sox while Isiah Kiner-Falefa slides over to cover shortstop once again.
