Keller and the Pirates won't face the Mets on Monday after the game was postponed due to inclement weather in Pittsburgh, Justice delos Santos of MLB.com reports.

EDGE Analysis

The two teams are set to make up the contest as part of a split doubleheader Wednesday. Because the Pirates have an open date in the schedule Thursday, the team isn't expected to add a temporary seventh starter to the rotation, so Keller should stay on schedule to make a start against the Mets either Tuesday or Wednesday. Bryse Wilson and Johan Oviedo are in line to start the other two contests of the series.

Keller allowed two earned runs on four hits and two walks while striking out 10 across six innings Tuesday against the Brewers. He did not factor into the decision.

EDGE Analysis

Keller racked up a career high in strikeouts, backed by 14 swinging strikes across 105 total pitches. He otherwise primarily kept the ball on the ground, with his only blemish coming on a two-run home run by Kolten Wong in the fourth frame. Keller still has inconsistent results from start to start, but he has maintained a 3.50 ERA with a 48:15 K:BB across 54 innings in his last 10 outings. He also owns a 4.43 ERA and 1.46 WHIP for the season but should continue to get chances to stack positive starts out of Pittsburgh's rotation to close the campaign.

Keller (4-10) took the loss in Wednesday's 14-2 rout at the hands of Atlanta, surrendering seven runs (two earned) on seven hits and two walks over 3.2 innings. He struck out five.

EDGE Analysis

The right-hander reeled off five straight quality starts sandwiched around the All-Star break, but Keller's solid run has come crashing to a halt as he's failed to get more than 11 outs in either of his last two outings. Fortunately for his ratios, a couple errors by Josh VanMeter kept any of Atlanta's five runs in the fourth from going on his ledger. Keller tossed 53 of 82 pitches for strikes Wednesday before getting the hook, and he'll carry a 4.50 ERA and 97:44 K:BB through 118 innings into his next start.

Keller (shoulder) will start Wednesday at home against Atlanta, Kevin Gorman of TribLive.com reports.

EDGE Analysis

He exited his start Tuesday with shoulder fatigue, and will end up getting a few extra days of rest while avoiding a stint on the injured list. Keller has a 4.26 ERA, 1.42 WHIP and 15:8 K:BB in 25.1 innings over his last five starts.

Keller (shoulder) was able to play catch Wednesday without any discomfort, Justice delos Santos of MLB.com reports.

EDGE Analysis

Keller's ability to do some light throwing one day after being pulled early in his start against the Red Sox is a good sign, but an upcoming bullpen session will be the real test of his health. If Keller's right shoulder presents no issues when he attempts to throw off a mound Thursday or Friday, he should be ready to make his next turn through the rotation Sunday against Cincinnati.

Keller was removed from Tuesday's start against the Red Sox after two innings due to right shoulder fatigue, Justice delos Santos of MLB.com reports.

EDGE Analysis

Keller had reduced velocity before leaving the contest, and he's in line for the loss after surrendering five runs (four earned) on five hits with three strikeouts and one walk over two innings. It's unclear if the shoulder fatigue will affect the 26-year-old's availability for his next turn through the rotation, which tentatively lines up for Sunday versus the Reds.

Keller (4-8) earned the win over Arizona on Wednesday, tossing 5.1 innings and allowing three runs on five hits and one walk while striking out three batters.

EDGE Analysis

Keller couldn't extend his streak of five straight quality starts, but he did something he wasn't able to do in any of his past four outings -- pick up a victory. The Pirates gave him an unusually decent amount of run support, and Keller capitalized by holding the Diamondbacks without an extra-base hit. The right-hander owned a 5.21 ERA through 16 starts on July 6, but he's been able to lower that to a much more respectable 4.25 with his recent solid stretch. Keller may finally be living up to the potential that made him a second-round draft pick by Pittsburgh in 2014.

Keller (3-8) took the loss Friday, allowing one run on eight hits and a walk over six innings in a 1-0 loss to the Orioles. He struck out one.

EDGE Analysis

The 26-year-old was stingy but not dominant, tossing 54 of 87 pitches for strikes before exiting, but Keller got outdueled by Baltimore's Dean Kremer. Keller has delivered five straight quality starts, posting a superb 1.74 ERA, 1.10 WHIP and 22:6 K:BB through 31 innings over that stretch as his offseason velocity gains appear to finally be paying off.

Keller gave up one earned run on five hits and three walks while striking out three over six innings in a 2-1 loss to the Phillies on Saturday. He did not factor into the decision.

EDGE Analysis

Keller issued a couple of early free passes and found himself in a bases-loaded jam in the first inning, but he got out of the frame with a couple of timely punchouts. He cruised through another five innings with the only damage coming on a J.T. Realmuto solo shot to right. After getting knocked around at the beginning of the season, Keller has been very effective in July, posting a 2.61 ERA over five starts. He will carry a 4.37 ERA and 1.42 WHIP into his next start.

Keller did not factor into the decision against the Marlins on Sunday, allowing three runs on five hits while striking out seven and walking none over six innings.

EDGE Analysis

Keller threw 51 of 74 pitches for strikes in the contest, but left the game with his team down by one. The righty has strung together some solid games in July, with three quality starts in a row including Sunday's outing. After lasting six innings once throughout April and May, Keller has six such games since the start of June. Not only does he seem to have a longer leash, but he is also pitching better. Keller has a 2.88 July ERA and has lowered his season ERA to 4.55, the lowest it has been all year.
