Castillo did not factor into the decision in Tuesday's loss to the Athletics, allowing two runs on four hits and a walk while striking out five over seven innings.

EDGE Analysis

Castillo only allowed four hits but two of them went for home runs, one by Lawrence Butler in the first inning and another by Seth Brown in the fourth. Castillo has now allowed nine home runs over his last five starts, though Tuesday was his first time reaching seven innings since July 19 and his first quality start since Aug. 11. The 31-year-old righty is putting together another strong campaign, yet the Mariners are 14-15 in his starts, partially due to the fact that they've scored two runs or fewer in 11 of Castillo's outings. For the year, he owns a 3.60 ERA, 1.15 WHIP and 172:46 K:BB in 172.1 innings and lines up to face the Cardinals in St. Louis over the weekend.

Castillo (11-12) picked up the win Wednesday, giving up two runs on six hits and two walks over 5.2 innings in a 6-2 victory over the Rays. He struck out four.

EDGE Analysis

The 31-year-old right-hander left the mound after 97 pitches (60 strikes) just short of his 18th quality start of the season, but it was still a solid performance from Castillo. In eight starts since the All-Star break, he's posted a 3.94 ERA, 1.19 WHIP and 51:11 K:BB through 48 innings. Castillo will look to keep rolling in his next outing, which is scheduled to come on the road early next week in Oakland.

Castillo is at a 3.66 ERA, 1.16 WHIP and 163:43 K:BB through 159.2 innings over 27 starts this year. He's projected for a home start versus the Rays next week.

He's now recorded seven straight quality starts while allowing one or fewer runs four times.

Castillo (9-11) took the loss Tuesday against the Tigers, allowing three runs on eight hits and no walks while striking out nine over six innings.

EDGE Analysis

Castillo kept the Tigers off the board until they plated the first run of the game in the fourth. Two more runs were scored against him in the fifth after the Tigers compiled four singles in the inning. It was the fourth time this season he's given up at least eight hits in a game, though only one hit went for extra bases.

While Castillo's K/9 has dropped from 10.0 to 8.6 this season, he's still been highly effective, posting a 3.43 ERA and 1.16 WHIP in 136.1 innings. He's tentatively lined up to make his next start Tuesday against the Tigers.

Castillo allowed five hits and issued two walks while striking out seven batters over six scoreless innings in a no-decision against the Angels on Wednesday.

EDGE Analysis

Castillo induced a modest nine whiffs, but he still managed to tally a healthy seven punchouts. The veteran hurler has tossed exactly six scoreless frames in two of his past three outings, and he's recorded a quality start in four straight appearances. Castillo's strikeout numbers are down this season -- he's on pace to record fewer punchouts than innings pitched for just the second time in his career -- but he's otherwise been reliable, posting a 3.38 ERA, 1.16 WHIP and 126:37 K:BB over 130.1 innings.

Castillo (8-10) allowed three runs on six hits and a walk while striking out three over seven innings, taking the loss Friday versus the Astros.

EDGE Analysis

All of the scoring came in the third inning, where Castillo allowed five straight batters (three hits, one walk, one hit-by-pitch) to reach base. While he was decent and efficient, needing just 90 pitches (58 strikes) to get through seven frames, the Mariners' offense once again came up cold. Castillo has logged three straight quality starts in July and now sits at a 3.55 ERA, 1.16 WHIP and 119:35 K:BB through 124.1 innings over 21 starts this season. He's projected for a favorable home start versus the Angels in his next outing.

The right-hander threw first-pitch strikes to 17 of 23 batters and induced 12 whiffs on the night to earn his second consecutive win. Castillo has now gone at least six innings in back-to-back outings after previously failing to do so in three straight. However, he's also issued multiple free passes in four of his last five starts.
