The Reds placed Castillo on the family medical emergency list Monday.

EDGE Analysis

Cincinnati had been listing Castillo as its probable starter for Tuesday's series opener against the White Sox in Chicago, but his availability for final week of the regular season is now in question following his deactivation. The team has yet to provide a timeline on Castillo's return to the roster, but he won't be eligible to rejoin the 28-man active roster for at least the next three days. Cincinnati called up Reiver Sanmartin from Triple-A Louisville in a corresponding move ahead of his scheduled start Monday against the Pirates, and he could pick up a second turn through the rotation over the weekend in Pittsburgh if Castillo isn't activated by then.

Castillo (9-15) allowed two earned runs on six hits and three walks while striking out six across six innings, taking the loss to the Nationals on Thursday.

EDGE Analysis

Castillo surrendered a solo home run to Juan Soto in the sixth inning and he didn't receive any run support from his offense. After struggling for much of the season, Castillo is averaging less than two runs allowed per start over his last seven outings. The 28-year-old has a 4.05 ERA and 1.35 WHIP with 187 punchouts in 182.1 innings this season.

Castillo and the Reds won't face the Pirates on Wednesday after the game was postponed due to inclement weather in Cincinnati.

EDGE Analysis

The two teams will make up the contest next Monday, the lone mutual off day remaining in their respective 2021 schedules. In light of the postponement, expect Cincinnati to simply move all members of its five-man rotation back a day in the pitching schedule. Castillo will line up to make his next start in Thursday's series opener versus the Nationals at home.

Castillo (8-15) came up huge against the Dodgers on Friday night, shutting them out over 6.1 innings. He struck out 10 in the game while giving up five hits and issuing two walks.

EDGE Analysis

The fact that Castillo did this against the Dodgers, and with the Dodgers having Walker Buehler on the mound, makes this outing even more impressive. Castillo's ERA dropped to 4.08 on the season with this outing. He'll have a chance to bring that mark below 4.00 in his next outing.

Castillo hurled seven innings against St. Louis on Saturday, allowing four runs on eight hits and one walk while striking out five. He did not factor in the decision.

EDGE Analysis

The right-hander was staked to a four-run lead after three innings, but the Cardinals touched him up for a pair of runs in each of the third and sixth frames to erase the deficit. Castillo's streak of five straight quality starts was consequently snapped, though he did tie his season-high mark by completing seven innings. The 28-year-old hasn't taken a loss since Aug. 14, and he has brought an ERA that stood at 7.61 after 10 starts this season down to a respectable 4.24. Castillo's next outing is tentatively scheduled for Friday at home against the Dodgers.

Castillo (7-15) was tagged with the loss Sunday against the Tigers after allowing three runs (one earned) on four hits and two walks while fanning seven across six innings.

EDGE Analysis

Castillo tossed his fifth straight quality start but has been unable to deliver many wins in that span, going 1-4 with a 2.81 ERA and a 1.09 WHIP across 32 innings through that stretch. Castillo endured a slow start to the season but has picked things up of late and has allowed more than three earned runs just once since the beginning of June.

Castillo (7-14) allowed three runs on five hits and two walks over six innings Monday, striking out eight and taking a loss against the Cardinals.

EDGE Analysis

Castillo got off to a rough start, giving up a two-run shot to Paul Goldschmidt in the first inning. He managed to keep the Cardinals off the board over the next four innings before Tyler O'Neill poked an RBI single in the sixth. He's been hit with a loss in four of his last five outings with a 5.22 ERA during that span. Castillo will carry a 4.30 ERA into this weekend's projected home start against the Tigers.

Castillo (7-13) allowed two runs over 6.1 innings Wednesday night against the Brewers, striking out six while giving up four hits and two walks. Alas, opposing pitcher Brandon Woodruff was better, shutting the Reds out over six innings.

EDGE Analysis

Once again, Castillo was firing on all cylinders, hitting 99 mph on his fastball, and getting results with his changeup, which he threw 37 times, according to MLB.com's Mark Sheldon. Castillo is projected to start next against the Cardinals at home.

Castillo (7-12) allowed one earned run on eight hits and one walk while striking out seven across seven innings, earning the win over the Marlins on Thursday.

EDGE Analysis

Castillo's one run against him came in the fourth inning on a Jorge Alfaro single. He allowed just one extra-base hit through seven innings. Over his last seven outings, six have been quality starts. He carries a 4.35 ERA and 1.40 WHIP with 145 strikeouts in 144.2 innings. His next start is projected to be on Wednesday in Milwaukee.

Castillo (6-12) took the loss Saturday, allowing three runs on five hits and two walks over 6.2 innings as the Reds were downed 6-1 by the Phillies. He struck out eight.

EDGE Analysis

The right-hander delivered his fifth quality start in his last six outings and 12th of the season, but the Cincy offense didn't even manage a hit until the eighth inning, giving Castillo no margin for error. He'll carry a 4.51 ERA and 138:59 K:BB through 137.2 innings into his next start.
