Mitch Keller - MLB News, Rumors, & Updates

Seven strong innings in second win Keller (2-1) notched the win Sunday against the Rays, allowing two runs on five hits and no walks in seven innings. He struck out five.

Impact It was perhaps a season-best performance by the right-hander, who worked a season-high seven frames and fanned a season-most five Sunday. Keller has done a fine job of providing length for the Pirates so far in 2026, tossing at least six innings in four of his five starts. He'll bring a strong 2.79 ERA, 1.10 WHIP and 19:9 K:BB over his first 29 frames into his next outing, which is currently projected to come against the division-rival Brewers.

Tagged for five runs in loss Keller (1-1) took the loss Monday against the Nationals, allowing five runs on six hits and four walks with three strikeouts across four innings.

Impact Keller had turned in three straight six-inning quality starts to begin the season, so Tuesday was his first hiccup of the 2026 campaign. The Nationals attacked Keller early and often in this one, as the first five batters of the game reached base to push across three runs. CJ Abrams then swatted a solo home run off Keller in the third frame. Keller generated just seven whiffs on 90 pitches and walked four batters for the second time in four starts. The right-hander now owns a 2.86 ERA and 14:9 K:BB across 22 innings. He's slated to face the Rays at home Sunday in his next start.

Blanks Friars in no-decision Keller didn't factor into the decision in Wednesday's 8-2 loss to the Padres, allowing three hits and a walk over six scoreless innings. He struck out four.

Impact The veteran right-hander was masterful over 75 pitches (49 strikes), but manager Don Kelly elected to lift Keller to begin the seventh inning in a scoreless tie and watched his bullpen immediately implode. Keller has begun the season with three straight quality starts but has won only one of them, delivering a 1.00 ERA, 0.94 WHIP and 11:5 K:BB through 18 innings. He'll look for more run support in his next trip to the mound, which is set to come at home early next week against the Nationals.

Picks up win over Baltimore Keller (1-0) earned the win over the Orioles on Friday, allowing two runs on six hits and two walks with four strikeouts across six innings.

Impact Keller has logged back-to-back quality starts to open the season and will carry a 1.50 ERA into his next start Wednesday against the Padres. The right-hander has thrown at least 175 innings with at least 150 strikeouts in three straight seasons coming into the 2026 campaign. He's not an exciting fantasy proposition, but Keller is durable and reliable.

APRIL 4 • ROTOWIRE

Goes six scoreless in no-decision Keller did not factor into the decision in Saturday's 4-2 extra-innings loss to the Mets, allowing three hits and no walks with three strikeouts over six scoreless innings.

Impact Keller was extremely efficient, needing just 77 pitches to blank the Mets over six innings. It was an encouraging outing for the 29-year-old, who has logged 175-plus frames in each of his past three seasons. He lines up for a home matchup against the Orioles next weekend.

Makes adjustment to changeup Keller adjusted the grip on his changeup during the offseason, Kevin Gorman of the Pittsburgh Tribune-Review reports.

Impact Keller throws a wide range of pitches and consistently tinkers with his offerings, though his changeup has never been a major part of his arsenal. It's unclear exactly how he changed the pitch, but he threw it six times in his spring debut Sunday against the Rays -- all against lefties. Keller reported feeling comfortable with the pitch, per Kevin Gorman of the Pittsburgh Tribune-Review, so it could be a more prominent part of Keller's game plan in 2026.

FEBRUARY 24 • ROTOWIRE

First spring start scheduled Keller will make his Grapefruit League debut Sunday against the Rays, Jason Mackey of the Pittsburgh Post-Gazette reports.

Impact Keller has turned into a consistent starter for the Pirates, though he endured a tough second half of 2025 by posting a 5.56 ERA and 1.50 WHIP across 57.1 innings. He's looking to be more consistent in 2026, but he's posted an ERA in the low 4.00s with a WHIP in the mid 1.20s in each of the last three seasons. Keller will remain a stalwart in the rotation in 2026 and could serve as the No. 2 starter behind Paul Skenes.

FEBRUARY 20 • ROTOWIRE

Labors in no-decision Keller didn't factor into the decision Friday against Atlanta, allowing one run on three hits and five walks in 3.2 innings. He struck out six.

Impact Keller lacked control in his last start of the campaign, issuing his most walks of the year in his shortest outing since Aug. 19 against Toronto. In fact, the right-hander lent more free passes Friday than he did in his prior five appearances combined. Keller will be entering the third season of his five-year contract with the Pirates in 2026, and he remained a solid if unspectacular fantasy starter in 2025. Through 176.1 innings, he posted a 4.19 ERA, 1.26 WHIP and 150:51 K:BB.

SEPTEMBER 27, 2025 • ROTOWIRE

Serves up two homers in loss Keller (6-15) allowed four earned runs on four hits and a walk while striking out four across five innings to take the loss Friday against the A's.

Impact Keller had a smooth start to the outing, as he retired the first nine batters he faced. However, he allowed a solo home run in the fourth inning, followed by a three-run shot a frame later to ruin his day. Keller has now allowed at least one home run in six straight starts and has a 5.87 ERA paired with a 1.45 WHIP across 53.2 innings since the All-Star break.

SEPTEMBER 20, 2025 • ROTOWIRE

Takes no-decision Keller did not factor into the decision Friday, allowing two runs on four hits and one walk over 5.1 innings in a 6-5 loss against Washington. He struck out four.

Impact The right-hander appeared on his way toward his seventh victory of the season with a 3-0 lead through five frames, but he was charged with a couple runs on three hits in the sixth before the Pirates bullpen faltered an inning later. Keller entered the All-Star break with a 3.48 ERA across 119 innings, but he has a 5.73 ERA in 10 starts since the midseason break.

SEPTEMBER 13, 2025 • ROTOWIRE

Out-dueled by Woodruff Keller (6-14) took the loss Saturday, allowing two runs on five hits over 6.1 innings as the Pirates were downed 4-1 by the Brewers. He struck out four without walking a batter.

Impact It was arguably Keller's best performance since the All-Star break, with a two-run homer by Jake Bauers in the fourth inning being the only blemish on his line, but the right-hander had no margin for error with Brandon Woodruff firing goose eggs over six innings for Milwaukee. The quality start was Keller's 17th of the season, one off his career high, but only two of them have come in seven outings since the beginning of August -- a stretch in which he's stumbled to a 5.86 ERA, 1.44 WHIP and 36:11 K:BB through 35.1 innings. He'll try to build on this effort in his next trip to the mound, which is scheduled to come on the road next weekend against the Nationals.

SEPTEMBER 7, 2025 • ROTOWIRE

Falls to Boston Keller (6-13) took the loss Sunday against the Red Sox, allowing four runs (none earned) on four hits and a walk across five innings. He struck out seven.

Impact After blanking the Red Sox through four innings, Keller fell victim to some poor defense behind him in the fifth -- Romy Gonzalez reached via error to start the frame before Jarren Duran legged out a three-run, inside-the-park home run with two outs. While he wasn't charged with an earned run Sunday, Keller has been shaky of late, posting a 7.59 ERA across seven starts coming into the day. Overall, the right-hander sports a 4.21 ERA with a 1.28 WHIP and 132:44 K:BB across 28 starts (156 innings) this season.

Punches out nine Keller (6-12) got the win over the Cardinals on Tuesday, allowing three runs on three hits and a walk while striking out nine in six innings.

Impact Keller was nearly through four scoreless frames, but Nolan Gorman took him deep for a two-run shot with two outs to get the Cardinals on the board. Keller racked up a season-high nine strikeouts and recorded his first quality start since July 22. He's now up to 16 quality starts this season, which is tied for the ninth-most in baseball. Keller will look to build on his positive outing when he takes on the Dodgers in a home start next week.

Can't slow down Brew Crew Keller (5-11) took the loss Wednesday, surrendering six runs on eight hits and two walks over four innings as the Pirates were downed 12-5 by the Brewers. He struck out five.

Impact The right-hander couldn't stop Milwaukee from winning its 12th straight game, getting tagged for more than five runs for the first time since June 5 and getting handed his first loss since June 21. Since the latter outing, Keller has posted a 4.34 ERA, 1.36 WHIP and 39:15 K:BB through 47.2 innings over nine starts. He'll look to rebound in his next trip to the mound, which is scheduled to come at home early next week against the Blue Jays.

AUGUST 14, 2025 • ROTOWIRE

Solid despite command issues Keller did not factor into the decision in Friday's 3-2 win over the Reds, allowing two runs on six hits and three walks with three strikeouts over 5.2 innings.

Impact Keller departed an out shy of a quality start after allowing two baserunners in the sixth inning, one of whom came around to score. The 29-year-old threw just 56 of 97 pitches for strikes with only six whiffs, but the two earned runs marked his lowest total in four starts since the All-Star break. He'll carry a 3.86 ERA, 1.23 WHIP and 107:37 K:BB across 137.2 innings into a road matchup with the Brewers next week.

Struggles with long ball in win Keller (5-10) earned the win Sunday against the Rockies, allowing five runs on seven hits and one walk while striking out four over five innings.

Impact Keller cruised through the first five frames Sunday, but things unraveled quickly in the sixth when he surrendered back-to-back-to-back home runs to Mickey Moniak, Hunter Goodman and Jordan Beck before exiting. Despite the rough ending, the Pirates' offense provided enough run support to secure the win for Keller. The 29-year-old hasn't looked sharp since the All-Star break, posting a 7.62 ERA with a 12:7 K:BB over 13 innings in three starts. The right-hander will aim for a cleaner outing in his next scheduled start against the Reds.

Completes just two frames Monday Keller allowed three runs on five hits and three walks while striking out three batters over two innings in a no-decision against San Francisco on Monday.

Impact It was a slog from the start for Keller, who allowed three baserunners and one run in the first inning. The Giants tagged him for two more runs in the second, though Keller at least managed to avoid a disastrous frame by striking out two batters with the bases loaded. However, the right-hander finished that inning at 73 pitches -- just 42 of which were strikes -- and didn't return for the third. This was Keller's shortest outing of the campaign and the first time in 20 starts that he's failed to complete five frames. Pittsburgh was able to pull out the win, however, so Keller remains without a loss on his record since June 21.

Extends undefeated streak Keller (4-10) picked up the win Tuesday, giving up three runs on six hits and three walks over six innings in an 8-5 victory over the Tigers. He struck out five.

Impact It wasn't the right-hander's sharpest outing, but Keller delivered his fourth straight quality start and 15th of the season on 89 pitches (59 strikes). After getting very little run support early in the year, he's now gone five straight starts without taking a loss, going 3-0 with a 2.03 ERA, 0.97 WHIP and 24:6 K:BB over 31 innings during that stretch -- and boosting his trade value significantly, should Pittsburgh decide to move him by the deadline. Keller will look to keep rolling in his next trip to the mound, which lines up to come on the road early next week in San Francisco.
