Castillo (4-6) allowed four runs on six hits over four innings in a loss to the Twins on Saturday. He struck out four and did not issue a walk.

EDGE Analysis

Castillo had a bit of a letdown performance after the Reds clinched a postseason berth Friday night. He allowed four extra-base hits (all doubles), the most he's allowed in a start this season, but Castillo was smiling throughout and seemed just fine, albeit not completely dialed in. The win-loss record does not do Castillo's 2020 regular season justice -- he was one of the best pitchers in the National League by any other measure. The right-hander lines up to start Game 2 for Cincinnati in the wild-card round.

Castillo (4-5) picked up the win Monday against the Brewers, allowing one run on four hits and three walks across 6.2 innings. He struck out nine.

EDGE Analysis

Castillo was sharp once again Monday, with his lone hiccup being a solo shot by Jedd Gyorko in the fifth. The right-hander has won each of his last four starts, punching out 33 while allowing just four runs across 28.2 frames. After starting the campaign 0-5, Castillo will have a chance to even his record when he takes the ball Saturday in Minnesota.

Castillo (3-5) allowed three hits and one walk over seven scoreless innings in a win over the Pirates on Wednesday. He struck out 10.

EDGE Analysis

The right-hander put the team on his back once again after going the distance his last time out. He induced 18 swinging strikes on 91 pitches en route to his second double-digit strikeout performance of the season, and now has a 1.23 ERA and 24:6 K:BB in his last three starts. Castillo endured some tough luck early and did not get much support from his teammates, but the surface numbers are finally starting to match up to his underlying dominance. He lines up to start Tuesday at home against the Brewers and could potentially go again the final day of the regular season, Sept. 27 at Minnesota, if the Reds are still in it.

Castillo (2-5) pitched a nine-inning complete game, allowing a run on two hits and three walks while striking out six in Friday's win over the Cardinals.

EDGE Analysis

Castillo emptied the tank in this game, throwing 112 pitches (73 strikes) while allowing just one extra-base hit. The only run he allowed happened in the second inning when Matt Carpenter's groundout allowed Brad Miller to score. Castillo's put together good outings in each of his last two starts. He now has a 3.44 ERA, 1.32 WHIP and 66:20 K:BB across 52.1 innings this season. The right-hander is expected to face the Pirates on Wednesday in his next start.

Castillo (1-5) allowed two runs on seven hits and two walks while striking out eight over six innings as he earned the win in Game 1 of Friday's doubleheader against the Pirates.

EDGE Analysis

Castillo has been dominant at forcing strikeouts this season, but he's struggled to limit run production. As a result, he was charged with losses in five of his last six starts. However, he took advantage of the struggling Pirates in Friday's matinee to enter the win column for the first time this season. The right-hander now carries a 3.95 ERA and 60:17 K:BB over 43.1 innings in 2020. His next start should come on the road Thursday against the Cubs.

Castillo (0-4) was charged with three runs (two earned) on five hits over six innings in a loss to the Brewers on Tuesday. He struck out nine.

EDGE Analysis

Castillo was quite good, but he was let down not only by his offense (again), but by his defense as well. Joey Votto misfired a throw to second base as he tried to turn two in the fourth inning, and that error led to the Brewers scoring all three of their runs in the game. Castillo is a perfect example of the limitations of win-loss record and ERA; he is winless with a 4.18 ERA, but Castillo has a 45:14 K:BB and only one homer allowed, fueling one of the best FIPs among MLB starters. The Reds will look to finally get him into the win column Sunday at home against the Cubs.

Castillo (0-3) was charged with four runs (three earned) on five hits over 3.1 innings in a loss to the Royals in the first game of Wednesday's doubleheader. He struck out five and walked two.

EDGE Analysis

Making his first start in eight days after the team's COVID-19 scare, Castillo was not particularly sharp. He needed 35 pitches to get through the first frame and ended up recording only 10 outs on 89 pitches. The right-hander has made two starts against Kansas City and two against Detroit and yet remains winless on the year. Everything checks out just fine in the peripherals and Castillo should still be considered a top-15 starting pitcher in the NL, even if he's been the third-best starter on his own team to this point. Next week he gets the Brewers in Milwaukee and then the Cubs at home.

Castillo gave up three runs (one earned) on seven hits and two walks over six innings during Tuesday's extra-inning win over the Royals. He had five strikeouts and did not factor in the decision.

EDGE Analysis

The right-hander wasn't exactly dominant with his lowest strikeout total of the season, but he exited in line for the win before Cincinnati's bullpen surrendered two runs in the eighth inning. Castillo has a 3.91 ERA, 1.44 WHIP and 31:6 K:BB through four starts (23 innings) and has a favorable matchup versus the Pirates on Sunday.

Castillo (0-2) allowed three runs on four hits and four walks while striking out nine over five innings in a loss to Cleveland on Thursday.

EDGE Analysis

Jose Ramirez turned around a 3-2 fastball in the first inning against Castillo, and the right-hander was more generous with the free passes than he was in his first two starts. However, this was far from a bad performance; Castillo just got no support from his teammates. The Reds were shut out once again and have scored a total of seven runs in the three games Castillo has started. He will look to finally get in the win column next week at home against the Royals.

Castillo (0-1) allowed five runs on eight hits and one walk while striking out six over six innings in a loss to the Tigers on Friday.

EDGE Analysis

Manager David Bell let Castillo begin the seventh inning, and while that decision was justified, it backfired. Detroit got to Castillo for three straight singles before he was pulled and extended a one-run lead to a three-run lead in the frame. Castillo appeared primed for a hot start with two straight matchups against the Tigers to begin the season, but he has a 4.50 ERA and a zero in the win column. A 17:2 K:BB portends good things to come, though he's going to face stiffer competition his next time out with a road matchup in Cleveland on the docket.
