Hit hard in no-decision Castillo came away with a no-decision in Friday's 11-9 win over the Mets, surrendering six runs on nine hits -- including three home runs -- and a walk over four innings. He struck...
Impact The ball was flying at Citi Field, as the Mariners set a club record with nine doubles, while the two teams combined for five total homers. Castillo did his part to add to the fireworks, serving up two longs balls to Francisco Lindor and another to Juan Soto. It's the second time this season he's been taken deep three times in the same game, but his 10.4 percent HR/FB rate on the season is actually his lowest mark since 2022. Castillo could have trouble keeping the ball in the park in his next start as well, which lines up to come on the road next week in Philadelphia.

Settles for no-decision Friday Castillo didn't factor into the decision in Friday's 3-2 win over the Rays, giving up two runs on five hits over seven innings. He struck out five without walking a batter.
Impact All the damage off the veteran righty came on solo shots by Brandon Lowe in the first inning and Junior Caminero in the sixth, but all of Seattle's offense came on a three-run blast by Cal Raleigh in the eighth. Castillo delivered his 14th quality start of the year on 99 pitches (72 strikes), and he's allowed three earned runs or fewer in eight straight trips to the mound, posting a 2.25 ERA, 1.02 WHIP and 45:7 K:BB through 48 innings over that span. He'll look to get back in the win column in his next outing, which is scheduled to come on the road next weekend against the Mets.

Tosses seven sterling frames Castillo (8-6) earned the win over the Athletics on Monday, allowing one run on five hits and no walks while striking out four batters over seven innings.
Impact Castillo was more crafty than overpowering in the outing, as he notched just six whiffs and four punchouts. The veteran right-hander allowed only six baserunners (on five hits and one hit batsman), with the Athletics' lone run coming on a fielder's choice in the sixth frame. This was Castillo's 13th quality start of the campaign, tied for 11th-most in the majors. He's putting together another steadily reliable season, posting a 3.19 ERA, 1.21 WHIP and 111:36 K:BB through 127 innings spanning 22 starts.
