Keller did not factor in the decision against Arizona on Saturday, tossing seven scoreless innings during which he allowed one hit and five walks while striking out four batters.

EDGE Analysis

Keller was a bit wild in the contest, throwing just 57 of 99 pitches for a strike and walking a season-high five hitters. However, the free passes didn't hurt him since he didn't allow more than one in any frame and yielded just one hit (a sixth-inning single by Ketel Marte). Following a rough patch in late May and early June, Keller has notched four quality starts over his past six outings, a span during which he's posted a 2.68 ERA and 1.03 WHIP. The right-hander heads into the All-Star break in the midst of a career-best campaign in which he's recorded a 3.31 ERA, 1.12 WHP and 129:34 K:BB over 117 innings while posting a 9-4 record.

Keller (9-4) took the loss Monday versus the Dodgers, allowing five runs (four earned) on eight hits and a walk while striking out seven over five innings.

EDGE Analysis

The Dodgers did their damage early in the game, as they managed just one hit over three innings versus two Pirates relievers. Keller had a couple of stumbles in June -- he's allowed exactly one run in three of his last six starts, but he's also given up at least four runs in the other three outings in that span. The right-hander is now at a 3.52 ERA, 1.14 WHIP and 125:29 K:BB through 110 innings over 18 starts. Keller is projected for a road start this weekend against the Diamondbacks.

Keller (9-3) allowed one earned run on four hits and two walks while striking out five across six innings to earn the win Wednesday against the Padres.

EDGE Analysis

Keller allowed a pair of hitters to reach base in each oh his first two innings but settled in to quiet the Padres thereafter. Despite generating fewer swings-and-misses of late -- he had only three swinging strikes across 104 total pitches Wednesday -- he has allowed only one earned run in three of his last four starts. Keller is also tied for fourth in the majors with nine wins, and he's picked up four positive decisions in his last seven outings.

Keller allowed one run on five hits and no walks while striking out five batters over seven innings in Thursday's no-decision against Miami.

EDGE Analysis

Miami starter Braxton Garrett made more noise with 13 strikeouts, but Keller matched him on the scoreboard with just one earned run over seven frames. The Pittsburgh hurler allowed just only extra-base hit (a double) and notched his 10th quality start of the campaign, tied for ninth-most in the league. While Keller has had some bumps of late -- he came into Thursday with a 6.14 ERA and 1.50 WHIP over his past five starts -- he's still putting up a career-best campaign overall. Through 16 starts, he's already notched a career-best eight wins while posting a 3.45 ERA, 1.11 WHIP and 113:26 K:BB over 99 innings.

Keller (8-3) took the loss against Milwaukee on Saturday, allowing four runs on five hits and three walks while striking out seven batters over five innings.

EDGE Analysis

Keller yielded a pair of two-run innings, which was enough to send him to defeat in a game during which Pittsburgh couldn't push any runs across the plate. The right-hander has given up four or more runs in four of his past five starts after doing so only once through his initial 10 outings. The rough stretch has pushed his season ERA to 3.62 after it sat at 2.44 less than a month ago. Keller is still racking up strikeouts -- he's fanned at least seven all but once during the recent downturn -- so it's likely wise to stick with him in most fantasy formats to see if he's able to turn things back around. He's tentatively lined up for a road start in Miami his next time out.

Keller (8-2) earned the win Sunday, allowing one run on two hits and two walks over seven innings against the Mets. He struck out seven.

EDGE Analysis

Keller had been struggling coming into Sunday's matchup -- he pitched to a 7.79 ERA, allowing 15 runs on 25 hits, over his last three starts (17.1 innings). He responded with a dominant performance against the Mets, allowing a lone run on Jeff McNeil's fourth-inning homer. Keller lowered his ERA to 3.41 with a 1.11 WHIP and an impressive 101:23 K:BB through 14 starts (87 innings) this season. He'll look to keep rolling in his next outing, currently lined up as a road matchup with the Brewers.

Keller (7-2) took the loss Tuesday, allowing five runs on eight hits and four walks over 5.1 innings in a 11-2 loss against Oakland. He struck out one.

EDGE Analysis

Keller struggled Tuesday, tying his season high of four walks while setting a new low in strikeouts. The outing continued a concerning stretch of starts for Keller, who has accrued a 7.79 ERA and a 17:7 K/BB while allowing 25 hits over his last three starts (17.1 innings) after holding a 2.44 ERA with 77 strikeouts in his first 10 appearances (62.2 innings). Though fantasy managers were likely disappointed by his struggles against MLB's lowest scoring offense, they shouldn't hesitate to come back to Keller for his next start, which is expected to come against the Cubs at Wrigley Field.

Keller (7-1) earned the win Wednesday, allowing four runs on 10 hits and one walk across six innings during a 9-4 victory over the Giants. He struck out eight.

EDGE Analysis

Keller allowed a season-high 10 hits, but he got plenty of run support and cruised to his seventh win. The right-hander has given up 10 runs over his past two starts (12 innings) after surrendering just 13 across his previous nine appearances (58 innings). His ERA has ballooned to 3.25, but he still holds a superb 1.08 WHIP and 93:17 K:BB across 74.2 innings. Despite back-to-back rocky starts, Keller remains the ace of the Pirates' pitching staff and will look to reclaim his dominant form in his next start, which tentatively lines up as a home start versus Oakland.

Keller (6-1) picked up the win Friday over the Mariners, allowing six runs on seven hits and two walks while striking out eight over six-plus innings.

EDGE Analysis

Keller versus George Kirby looked like a pitchers' duel on paper, but it ended up being a slugfest in practice. Keller was taken deep twice in his worst start since Opening Day, but he was still the better of the two starters. He's rarely one to give up many homers, having allowed just seven across 11 starts this season. The rough outing raised Keller's ERA to 3.01 with a 1.02 WHIP and 85:16 K:BB through 68.2 innings. He'll look to put this one behind him next week in San Francisco.

Keller did not factor into the decision Saturday, allowing two runs on three hits over six innings against the Diamondbacks. He struck out eight.

EDGE Analysis

Keller worked his way through the Diamondbacks' lineup with relative ease, retiring 16 straight batters after allowing a solo homer to Ketel Marte in the first inning, racking up eight strikeouts without walking a single batter. Keller has been one of the best pitchers in baseball over the past month, allowing just five earned runs over his last five starts (33.0 innings), picking up four wins and boasting an incredible 47:3 K/BB over that stretch. The right-hander was on his way to picking up another win Saturday, handing the ball off to the bullpen with a 3-2 lead after six innings, but he had the win spoiled after Pavin Smith launched a two-run home run off Robert Stephenson to give Arizona the lead in the seventh. Keller is slated to take the mound next in a road series against the Mariners, who strike out at the second-highest rate in MLB.
