Diaz, 20, is hitting .217/.284/.333 with two home runs, eight RBI and one steal through 16 games with High-A Carolina.

Diaz continues to strike out with entirely too much frequency, fanning 20 times to begin the season. Still, he is not afraid to take a walk, and has shown much more pop than expected for his size and position. The Brewers have no reason to rush him to the bigs with Orlando Arcia and Mauricio Dubon technically ahead of him in the pecking order.

Arroyo -- who went 0-for-4 in his major-league debut Monday -- is expected to primarily start at third going forward, according to Alex Pavlovic of CBS Sports.

The 21-year-old didn't record a hit in his first game with the big club, but he didn't look outclassed at the plate either, seeing 20 pitches in his four at-bats. With the Giants' offense struggling to get off the ground, Arroyo should be given a strong look at third base to see if his bat can inject some life into the team. He is a rookie, so he will likely experience some ups and downs, but he is definitely worth an add to see if he can continue the success he was having with Triple-A Sacramento this season (.446/.478/.692).

Hernandez started in center Monday, batting eighth and going 1-for-3 in a loss to the Giants.

Hernandez -- who normally starts primarily against lefties -- got a start in place of the injured Joc Pederson (groin) against a right-hander. It appears that the 25-year-old will receive a short stint of regular playing time while Pederson heals on the disabled list. Even with a regular role, Hernandez's career .233 batting average against righties limits his value to deep and NL-only formats.

Solarte went 3-for-5 with three singles and a run scored in Monday's 7-6 loss to Arizona.

After a recent cold stretch, Solarte now has a modest five-game hitting streak and raised his average to .267 with his third three-hit performance of the season. The 29-year-old doesn't hit for much power, but his high contact rate makes him a good bet to help owners once again with a respectable average. Solarte's multi-position eligibility is another aspect that makes him a decent utility player in deep mixed formats.

Frazier was placed on the 10-day disabled list Monday with a hamstring strain.

Frazier was hitting .306 with a home run and five RBI through 15 games this season. Pitching prospect Dovydas Neverauskas has been promoted from Triple-A to fill his roster spot. It's unclear how long Frazier will be sidelined with the injury, though more should be known once the Pirates update his status. For the time being, Jose Osuna should see most of the reps in right field, but an outside move could be in the making if Frazier needs to miss extended time.

Arroyo had his contract purchased from Triple-A Sacramento on Monday, John Shea of the San Francisco Chronicle reports.

Arroyo will join the Giants as Aaron Hill heads to the disabled list in a corresponding move. He's set to bat sixth and play third base in his big-league debut Monday. The Giants' top prospect has been mashing in Triple-A this season, working a triple slash of .446/.478/.692 through 69 at-bats (16 games). It's unclear how long he'll remain with the big club, but if his production is able to carry over, it will be difficult to keep his bat out of the majors.

Frazier is out of the lineup Monday against the Cubs.

The Pirates are facing a left-handed starter for the second day in a row, so Frazier will once again cede duties in right field to Jose Osuna. Frazier should still be on tap to serve as the club's leadoff hitter against right-handed pitching for the duration of Starling Marte's (suspension) absence.

Dubon has gone 14-for-40 (.350) with a home run, seven RBI and six stolen bases over his last 10 games with Double-A Biloxi.

Dubon tallied just five hits and one steal over his first seven games of the season, but it didn't take him long to get on track. He's playing for the Brewers for the first time this year after being acquired from the Red Sox during the offseason, and Dubon is considered one of the better prospects in a quality farm system.

Green was outrighted to Triple-A Syracuse on Sunday, Chelsea Janes of the Washington Post reports.

The Nats designated Green for assignment earlier in the week but Green will remain in the Washington system, having passed through waivers unclaimed. A first-round pick in 2009, Green is merely an organizational depth piece. He has totaled 353 plate appearances in parts of five seasons at the major-league level (97 plate appearances since the start of the 2015 season).

Frazier is not in the lineup for Sunday's game against the Yankees.

With left-hander Jordan Montgomery toeing the rubber for the Yankees on Sunday, Frazier will head to the bench in favor of the right-handed hitting Jose Osuna.
