Perdomo (6-8) allowed two earned runs over 6.0 innings en route to a no-decision Thursday against the Cardinals. He gave up seven hits and two walks while striking out two batters.

EDGE Analysis

Perdomo had the unenviable task of opposing St. Louis ace Carlos Martinez on Thursday, but he held his own as he left the mound with the score tied. He was also efficient, needing just 78 pitches to get through those six frames. Perdomo now owns a 4.54 ERA over 12 starts in the second half and is lined up to face Matt Moore and the Giants at home Tuesday for his next outing.

Perdomo (6-8) gave up five runs (three earned) on six hits and three walks with five strikeouts over six innings and took the loss Friday against the Nationals.

EDGE Analysis

Perdomo has walked multiple batters in six of his last seven starts now, a stretch in which he has just a 24:17 K:BB and a brutal 5.77 ERA. Control has plagued him throughout his young career, and if Perdomo can't figure out a way to keep runners of the bases, his velocity won't save him from big innings.

Perdomo (6-7) allowed five runs on four hits and one walk across six innings in Sunday's loss to the Dodgers. He recorded one strikeout.

EDGE Analysis

Despite allowing just five baserunners, Perdomo's line looks poor due to his struggles in the fourth inning. All five runs on his ledger came during that frame via the home run -- a three-run shot from Justin Turner and a two-run blast by Yasmani Grandal. Perdomo has struggled of late, with four outings of at least four earned runs in has last six. His ERA now sits at 4.95 ahead of Friday's turn against the Nationals.

Perdomo (6-6) gave up two runs on seven hits and four walks over six innings in Tuesday's 7-3 win over the Reds. He struck out seven.

EDGE Analysis

He only threw 58 of 95 pitches for strikes, but Perdomo got enough help from over-eager Cincinnati hitters to record his 11th quality start of the year. The right-hander will face a tough task in his next outing Sunday on the road against the Dodgers.

Perdomo (5-6) allowed five runs on seven hits and two walks over six innings in Wednesday's 5-2 loss to the Twins. He struck out four.

EDGE Analysis

He's now been tagged for at least four runs in five of his last six starts, saddling Perdomo with a 5.75 ERA over that stretch that would be even worse if not for six of those runs being unearned. The 24-year-old will try to turn things around Tuesday on the road against the Reds.

Perdomo (5-5) allowed four runs on nine hits and two walks while striking out three batters through 6.2 innings during Thursday's win over the Mets.

EDGE Analysis

With a 4.76 ERA, 1.55 WHIP and 7.0 K/9, Perdomo's fantasy value is extremely low. In the right matchups, he could be utilized as a streamer or low-priced flier in daily contests, but his seasonal ownership should probably be limited to cavernous seasonal. Perdomo projects to face the Twins at Petco Park in his next start.

Perdomo (4-5) allowed four runs, one of which was earned, on eight hits and two walks while striking out four across six innings, but received no decision Saturday against the Giants.

EDGE Analysis

Perdomo had a 4-1 lead going into the fourth inning, but an error turned into easy inning into a three-run rally by the Giants that kept him from earning his fifth victory of the season. He's held opponents to three or fewer earned runs in five of his last seven starts, and although he owns a 4.71 ERA, he's been showing signs of improvement, and he's become a player that fantasy owners should take a close look at. He'll make his next start Thursday against the Mets.

Perdomo (4-5) allowed seven runs (five earned) on six hits and three walks over 2.1 innings during Monday's loss to the Rockies. He did not record a strikeout.

EDGE Analysis

After surrendering an earned run in each of the first two frames, Perdomo was quickly yanked from the game after allowing six of the first seven Rockies hitters to reach base in the bottom of the third en route to a lopsided five-run inning. The 24-year-old's ERA now sits at an unsightly 4.94 following his rough outing. He'll look to rebound during his upcoming scheduled start Saturday against the Giants.

Perdomo (4-4) allowed two runs (one earned) on nine hits over five innings in Wednesday's win over Cleveland. He struck out four.

EDGE Analysis

The 24-year-old righty pitched himself into some corners, but then he pitched his way right out. Perdomo throws hard and keeps the ball on the ground, and if he can improve on his walk rate, it wouldn't be surprising to see him shrink his ERA, which currently sits at 4.54, in the second half.

Perdomo (3-4) allowed four runs on seven hits and two walks while striking out four batters over 5.1 innings during Wednesday's win over Atlanta.

EDGE Analysis

Perdomo has flashed upside this season, and he's been particularly strong against right-handed hitters, limiting them to a .689 OPS and .300 wOBA. However, left-handed batters have posted .892 and .383 marks against him. Until Perdomo can narrow that gap, his fantasy upside is capped. While the 24-year-old righty has already shown progress in his second season in the majors, expectations should probably be kept in check for the remainder of 2017. A daunting road date with Cleveland is on deck for Perdomo.
