The Diamondbacks optioned Del Castillo to Triple-A Reno on Friday.

EDGE Analysis

Del Castillo missed out on Arizona's Opening Day roster after going 3-for-24 with 12 strikeouts in nine spring games. The 25-year-old could still see the big leagues at some point this season but isn't likely to see much playing time if Gabriel Moreno stays healthy.

Del Castillo (arm) will make his first start this spring at catcher Friday against the Royals.

Arizona optioned Del Castillo to Triple-A Reno on Monday.

EDGE Analysis

With top catcher Gabriel Moreno returning from the 10-day injured list Sunday, the Diamondbacks will roll with Jose Herrera as the No. 2 backstop. Del Castillo is slashing .313/.368/.525 over 87 major-league plate appearances this season, but he'll have an everyday role in Reno for the tail end of the Triple-A season. The move makes room on the Diamondbacks' 28-man roster for right-hander Scott McGough.

Del Castillo is out of the lineup for Sunday's game against the Brewers.

EDGE Analysis

With a left-hander (DL Hall) starting for the Brewers, the left-handed-hitting Del Castillo will head to the bench while Jose Herrera gets the nod behind the plate. Though Del Castillo had typically been seeing most of the starts against right-handed pitching since he was promoted from Triple-A Reno on Aug. 6, he and Herrera are both likely to see their opportunities diminish over the final two weeks of the season after Arizona reinstated top backstop Gabriel Moreno (adductor) from the 10-day injured list Sunday. Moreno could draw back into the lineup as soon as Monday in Colorado.

Del Castillo is out of the lineup for Friday's game against the Brewers.

EDGE Analysis

Del Castillo will give way to Jose Herrera for the fourth time in six games. Although two of those occurrences came against left-handed pitching, the Brewers are starting right-hander Freddy Peralta, which likely indicates that Del Castillo's playing time is trending downward.

Del Castillo went 2-for-4 with a double, a home run, three RBI and an additional run scored in Wednesday's 14-4 win over the Rangers.

EDGE Analysis

After the Rangers plated two runs in the top of the fifth inning, Del Castillo responded immediately with a three-run blast. He continues to split time behind the dish with Jose Herrera until Gabriel Moreno (thigh) is ready to return. The injured Moreno ramped up his activity this week, and the Diamondbacks are hoping for his return by mid-September. After an explosive debut to his MLB career -- three homers, 14 RBI in his first 48 at-bats -- Del Castillo has cooled off and entered Wednesday's contest hitting .130 (3-for-23) over the previous eight games.

Del Castillo is not in the lineup for Tuesday's game against the Rangers.

EDGE Analysis

Del Castillo has now started just two of the last six contests for the Diamondbacks. They've faced three lefties over that stretch, but the left-handed hitting Del Castillo has also been out of the lineup twice versus righties, including on Tuesday against Nathan Eovaldi. Jose Herrera will catch and bat ninth for Arizona.

Del Castillo isn't in Arizona's lineup for Saturday's game against the Astros.

EDGE Analysis

With Yusei Kikuchi slated to start for Houston, the lefty-hitting Del Castillo will retreat to the bench Saturday. Jose Herrera (head) will fill in behind the dish and bat ninth.
