Are the SF Giants preparing to promote hot-hitting infielder?

Every now and again, I have a good idea and it looks like the SF Giants were watching. On Monday, Alex Pavlovic of NBC Sports Bay Area indicated that Isan Díaz is currently on the Giants' taxi squad.

Are the SF Giants preparing to promote hot-hitting infielder?

The taxi squad usually consists of a couple of players and it is normally used as a precursor to another roster move or an injury precaution. With Díaz on the taxi squad, it seems to be a sign that the Giants are getting ready to add him to the active roster.

There is no news on if another position player is dealing with a nagging injury as the coaching staff is usually tight-lipped with injuries. The Giants are facing a left-handed pitcher in Dallas Keuchel tomorrow against the Arizona Diamondbacks, so they may hold onto Yermín Mercedes to play in that game before making a move.

Díaz swings from the left side, so there is more opportunity for playing time than Mercedes, who specializes against lefties and is not defensively versatile.

If the Giants select Díaz's contract, it could also be an opportunity to reward him after a strong showing with the Sacramento River Cats. The Giants originally acquired the 26-year-old infielder for cash considerations from the Miami Marlins at the end of April.

The middle infielder was once a top prospect, but Miami struggled to find playing time for him after he was outrighted off of the 40-man roster at the end of spring training. Since joining the Giants organization, Díaz has slashed .275/.372/.614 (135 wRC+) with 16 home runs, 40 RBI, and 39 runs in 199 plate appearances with the River Cats. This includes a 12.6 percent walk rate against a 27.1 percent strikeout rate.

However, he has struggled against major league pitching. In parts of three seasons with the Marlins, the left-handed bat registered a .562 OPS with nine home runs in 501 plate appearances. Development is not always linear, but Díaz never lived up to the hype that Marlins fans had when he was one of four prospects shipped to Miami from Milwaukee in exchange for Christian Yelich in 2018.

Given his age and pedigree, the Giants took a no-risk flyer on him with the potential for some upside. San Francisco has an open spot on the 40-man roster after cutting ties with Jake McGee, so no roster maneuvering would be necessary.

He has performed well since the trade and Giants fans have been eager to see what he can do with a change of scenery. It looks like they will not have to wait much longer.
