Manaea's slider has helped him dominate hitters of either handedness this season, Matt Kelly of MLB.com reports.

EDGE Analysis

The young left-hander's considerably wide and low release point has made it difficult for hitters to discern between his fastball and changeup, but his slider has begun to draw plenty of attention in its own right. Manaea has grown increasingly comfortable throwing the pitch, utilizing it 17.5 percent of the time as per Statcast after only deploying it at a 12.9-percent clip in 2016. Manaea has gotten swings and misses approximately 43 percent of the time and allowed just a .167 average over 86 at-bats when using the pitch, typically locating it low and inside to right-handed hitters while placing it low and away to lefty bats.

Manaea (8-5) allowed three earned runs off seven hits while striking out seven over seven innings during Thursday's no-decision against Toronto.

EDGE Analysis

Besides a couple home runs to Josh Donaldson and Kendrys Morales, Manaea was able to command the strike zone yet again, marking a fourth quality start in his past five outings. This was the first time since May 20 that Manaea didn't record a single base on balls, as the left-hander was able to throw strikes during 68 of his 99 pitches. On the year, the former Indiana State Sycamore has posted an ERA of 3.82 and 1.23 WHIP with an 8.7 K/9 for the A's. He projects to face the Giants in San Francisco for his next start.

Manaea allowed four runs on 10 hits and a walk while striking out just two batters over 5.2 innings during Saturday's loss to the Mets. He didn't factor into the decision.

EDGE Analysis

This wasn't Manaea's sharpest showing, and the two punchouts were his fewest in a start since returning from the disabled list May 15. It was a rare off outing, though. The lefty has been a strong fantasy asset this season with a 3.82 ERA, 1.25 WHIP and 8.8 K/9 for the campaign, and his eight wins are a solid total considering he's pitching for a basement-dwelling club. Manaea projects to face Toronto at the Rogers Centre in his next start.

Manaea allowed two earned runs over seven innings and picked up the win in Sunday's victory over the Indians. He allowed five hits and posted an 8:3 K:BB in the game.

EDGE Analysis

Manaea continues to throw the ball well for the A's and has allowed two earned runs or fewer in eight of 11 starts, a span over which he has lowered his ERA from 5.52 to 3.68. He will look to keep things going in his next start later this week against the Mets.

Manaea (7-5) allowed three runs on eight hits and a walk while striking out just three batters through seven innings during Friday's loss to the Mariners.

EDGE Analysis

Manaea has allowed three runs or fewer in nine of his past 10 starts and sports a 3.76 ERA, 1.21 WHIP and 9.0 K/9 for the year. The young lefty is emerging as a matchup-proof fantasy asset entering the second half, and there is potential the best is still ahead. It's worth noting that an innings cap could come into play for the 25-year-old Manaea -- especially with Oakland last in the AL West.

Manaea allowed two runs on six hits and two walks while striking out six batters through 7.1 innings during Sunday's loss to Atlanta. He didn't factor into the decision.

EDGE Analysis

The young lefty has now held opponents to three runs or fewer in eight of his past nine starts and sports a solid 3.75 ERA, 1.20 WHIP and 9.4 K/9 for the campaign. His 3.67 FIP is also right in line with his other statistics, so he projects to remain a strong fantasy asset moving forward. Manaea's game-to-game consistency is also encouraging. A road date at Safeco Field against the Mariners is up next.

Manaea (7-4) allowed one run on nine hits and three walks during Tuesday's 6-4 win over the Astros. He struck out three and was credited with the win.

EDGE Analysis

Manaea didn't have his best stuff going for him Tuesday, but was able to limit the hard-hitting Astros to just one run en route to his seventh win of the season. After facing the Yankees on June 16 and the Astros over his last two starts, Manaea will have the opportunity to face a more manageable opponent as he currently projects to square off against the Braves on Sunday.

Manaea (6-4) struck out eight while allowing three runs on seven hits and a pair of walks over six innings in Wednesday's home loss to Houston.

EDGE Analysis

After a five-run effort against the Yankees his last time out, Manaea bounced right back with a solid outing, although the result wasn't a favorable one. Still, his 81:28 K:BB over 73.1 innings should have his fantasy owners pleased even if his ERA remains a bit inflated at 4.05. If everyone stays on schedule, Manaea will rematch Mike Fiers and the Astros in Houston on Tuesday.

Manaea didn't factor into the decision in Friday's 7-6 win over the Yankees, giving up five earned runs on eight hits and two walks over six innings. He struck out seven.

EDGE Analysis

The young lefty did have the advantage of facing a Yankees squad that was sitting a couple of regulars, but he turned in a serviceable performance in many respects despite giving up five runs. Manaea notched 17 swinging strikes among his 107 pitches and was mainly done in by two mistakes, a three-run home run by Aaron Judge in the third and a solo shot by Chris Carter in the sixth. The 25-year-old did an impressive job keeping the ball down otherwise, inducing 11 groundballs overall. The outing did snap a five-start winning streak for Manaea, but he'll look to start a new one when he takes on the Astros at home next Wednesday.

Manaea (6-3) gave up two earned runs on six hits, two walks, a wild pitch and a hit batsman over seven innings during Saturday's 7-2 win over the Rays in the second game of a doubleheader. He struck out five.

EDGE Analysis

The lefty worked up to 103 pitches and racked up 20 swinging strikes over that span. It was Manaea's fourth consecutive quality start, as well as his fifth straight outing giving up two earned runs or less. He's notched victories in each of those contests while lowering his ERA from 5.52 to 3.67 in the process. He'll look to extend his current successful stretch when he tangles with the Yankees at home in his next start.
