Diaz was optioned to Triple-A Jacksonville on Friday, Christina De Nicola of MLB.com reports. Diaz hit just .146 with two home runs, 10 RBI and six runs during his time with the major-league club, and he posted a 29.4 percent strikeout rate. He'll attempt to sort things out in the minors after Miguel Rojas (finger) was reinstated from the 10-day injured list in a corresponding move. Jon Berti will likely serve as the primary third baseman going forward with Brian Anderson (shoulder) still on the shelf, while Deven Marrero could also see an uptick in playing time.
Diaz is out of the lineup for Wednesday's game against the Cardinals, Jordan McPherson of the Miami Herald reports. Diaz is one of four Marlins regulars getting a breather in the series finale; he'll be joined on the bench by Starling Marte, Adam Duvall and Jesus Aguilar. Deven Marrero, who was called up from Triple-A Jacksonville earlier Wednesday, will slot in at third base in place of Diaz, who is slashing a poor .186/.321/.233 through his first 13 games of June.
Diaz is out of the lineup for Sunday's game against Atlanta, Jordan McPherson of the Miami Herald reports. Diaz will sit for the second time in four games, and his grasp on the everyday role at third base could be loosening amid his ongoing struggles at the plate. Through 10 games in June, Diaz has posted a .576 OPS while striking out in 28.6 percent of his plate appearances.
Diaz isn't starting Thursday against the Rockies, Christina De Nicola of MLB.com reports. Diaz will get a breather after he went 5-for-18 with two doubles, two RBI, three walks and seven strikeouts in his last five games. Jon Berti will shift to the hot corner while Jose Devers starts at second base.
Diaz is not in the lineup Friday against the Pirates, Joe Frisaro of ManOnSecondBaseball.com reports. The 25-year-old started the past seven games, with the last three starts coming at third base, but he'll head to the bench after going 1-for-19 during the full period. Diaz should continue to see opportunities with Brian Anderson (shoulder) and Miguel Rojas (finger) sidelined, but the young infielder could see those chances diminish if he continues to struggle. Jose Devers will start at second base Friday while Jon Berti covers the hot corner.
