Castillo (5-1) picked up the win against the Cubs on Thursday, giving up two earned runs on two hits over 5.1 innings, striking out six and walking one as the Reds won 4-2. Castillo continues to dominate, as he picked up his fifth win in six decisions to start the season while providing yet another solid stat line. The right-hander is putting up Cy Young-caliber numbers at the outset of 2019, as he now boasts a fantastic 1.90 ERA, a 0.96 WHIP and a 76:25 K:BB through 61.2 innings.
Castillo threw six scoreless innings against the Giants on Friday night to get his fourth win of the season. He struck out 11 while allowing two hits and five walks. He generated 15 swings and misses on his changeup, accounting for nine of his strikeouts, and threw his changeup 40 times in the effort, Mark Sheldon of MLB.com reports. It's those five walks that drove Castillo's pitch count over 100 after six innings, leading to the early exit. He was facing a Giants team that scored four against him in his previous outing, his worst so far this season, albeit without Buster Posey, who is now on the injured list. He next faces a red-hot Cubs lineup back in Great American Ballpark, a challenge that will really test his newfound ace level.
Castillo yielded four runs on four hits and two walks over seven innings Sunday, taking the no-decision during a loss to the Giants. He struck out nine batters. Castillo had allowed just one baserunner via a fourth-inning walk through five frames. He then was drilled for four runs in the sixth, including a three-run shot from Buster Posey. It was the worst outing of the year for Castillo, who still owns a terrific 1.96 ERA and 59:19 K:BB. The 6-foot-2 righty will aim for revenge against San Francisco on Friday.
Castillo (3-1) allowed eight hits and no walks while striking out two across six scoreless innings to earn the win Thursday against the Braves. Castillo didn't rack up strikeouts but managed to scatter eight hits -- only one of which went for extra bases -- to turn in his second scoreless effort of the season. It's also notable that he did not issue a free pass as he has allowed three or more walks in three starts this season. That has yet to come back to haunt him, as he now has a 1.23 ERA and 0.95 WHIP across 36.2 innings for the campaign.
Castillo (2-1) struck out nine and allowed one run on four hits and one walk in six innings in a victory over the Padres on Saturday. The 26-year-old continues to dazzle early this season. He hasn't allowed more than two runs in any start and owns a 1.47 ERA this year. Opponents are hitting just .129 against him, which has helped Castillo also post a 0.88 WHIP. If owners have any complaints about him, it's that he's walked 14 in 30.2 innings, but he's also struck out 41. His next scheduled start is Friday in St. Louis.
