After allowing no runs to the Cardinals in his previous start, Keller struggled against St. Louis on Thursday throwing only 51 of his 90 pitches for strikes. The 25-year-old will carry a 6.75 ERA into his next start, tentatively scheduled against the White Sox in Chicago next week.

Keller (4-10) hurled five shutout innings to earn the win against St. Louis on Friday, allowing six hits and one walk while striking out six.

EDGE Analysis

The right-hander scattered six hits in the outing, but none went for extra bases. He threw 56 of 89 pitches for strikes and issued only one free pass despite tossing a first-pitch ball to 12 of the 21 batters he faced. Keller snapped a streak of four straight losses and picked up his first win since May 29. He'll carry a 6.35 ERA into his next start, which is likely to come at home against Arizona next week.

Keller (3-10) took the loss Saturday in the second game of a doubleheader against the Brewers, surrendering two runs on nine hits and a walk with three strikeouts over 4.1 innings.

EDGE Analysis

It was death by a thousand cuts for Keller, who allowed at least two baserunners in each of the five innings in which he appeared. He was able to keep the Brewers off the board through three before allowing a trio of singles -- one of them plating a run -- and a run-scoring groundout in the fourth. Keller notched one out in the fifth before being lifted with his pitch count at 77. Keller has lost all three of his starts since rejoining the rotation at the beginning of August, logging a dismal 6.28 ERA and 2.02 WHIP in 14.1 innings during that stretch. Those numbers aren't far off of the 6.86 ERA and 1.85 WHIP he's posted in 61.2 innings overall this season.

Keller is listed as the Pirates' probable starter for Saturday's game in Cincinnati, Kevin Gorman of TribLive.com reports.

EDGE Analysis

At least for this week, the Pirates will be sticking with a six-man rotation, allowing Keller and Bryse Wilson to make their second starts with the club after both were recently activated. After a nearly two-month stint at Triple-A Indianapolis, Keller faltered in his return to the Pittsburgh rotation last weekend versus the Phillies. He gave the Pirates five innings but was touched up for four runs on eight hits and no walks while striking out two.

Keller (3-8) was tagged with the loss Sunday against the Phillies after allowing four runs on eight hits while fanning two across five innings.

EDGE Analysis

Keller had a rough outing and while the bullpen was even worse, that can't hide the fact that the right-hander. He posted a 3.21 ERA across 28 innings at Triple-A, but he can't replicate those results at the big-league level and has posted a 7.05 ERA across 13 starts (52.1 innings). He has also given up at least four runs in three of his last five appearances.

Keller will start Sunday's game against the Phillies, Jake Crouse of MLB.com reports.

EDGE Analysis

Keller was promoted from Triple-A Indianapolis on Friday and will rejoin Pittsburgh's rotation two days later. The 25-year-old struggled with a 7.04 ERA in 12 starts before being demoted in mid-June to Triple-A, where he made eight starts and posted a 3.21 ERA, 1.43 WHIP and 39:13 K:BB across 28 innings.

Keller was recalled from Triple-A Indianapolis on Friday, Jason Mackey of the Pittsburgh Post-Gazette reports.

EDGE Analysis

The 25-year-old has been in the minors since mid-June and will rejoin the big-league roster ahead of this weekend's series versus the Phillies. Keller last pitched for Indianapolis on July 24, and he finished the stint at Triple-A with a 3.21 ERA, 1.43 WHIP and 39:13 K:BB over 28 innings. It's not clear when he'll take the mound, though he could slot into the rotation Sunday since Pittsburgh has yet to announce a starter for that day.

Keller allowed six runs (four earned) on seven hits and one walk in five innings for Triple-A Indianapolis on Saturday. He walked three while striking out nine batters.

EDGE Analysis

Since being demoted to the minors, Keller has compiled a 3.21 ERA in 28 innings for Indy but is still struggling with his command. While the 25-year-old has struck out 39 batters he's walked 13 (including nine in his last three starts). Keller will likely get another shot with Pittsburgh prior to season's end, but he hasn't dominated Triple-A the way the organization had hoped.
