Diaz earned the save Thursday after firing a perfect inning against the Rockies that included one strikeout.

EDGE Analysis

Diaz entered the ninth frame with a one-run lead and shut the Rockies down in order, striking out Dom Nunez in the process. With his ninth save of the season, the right-hander remains perfect in save opportunities while putting together a 3.10 ERA and 1.08 WHIP.

Diaz (undisclosed) is listed as an available reserve for Saturday's split-squad game against the Indians, Thomas Harding of MLB.com reports.

EDGE Analysis

Diaz had been shut down at one point during the Dominican Summer League with an injury, but his availability off the bench Saturday suggests he'll enter 2019 at full strength. The 19-year-old should head back to minor-league camp beginning Monday after the Rockies complete their split-squad games Saturday and Sunday.

Diaz is on the disabled list in the Dominican Summer League with an undisclosed injury.

EDGE Analysis

The 18-year-old speedster has a .309/.417/.436 slash line with zero home runs, 54 steals (on 62 attempts) and a 17:31 K:BB in 223 plate appearances before getting hurt. Since Diaz has not yet made his stateside debut, there's not much public scouting data available, so it's unclear if he's a 70- or 80-grade runner, but Diaz is certainly a burner. He also has a pretty good handle of the strike zone. His speed, patience and contact skills are appealing traits that make him a worthwhile flier in dynasty leagues.
