October is going to look different this season with no off days in scheduled in each of the first three rounds. There is some time off between each round, but bullpens are going to be even more important in this tight schedule. These power rankings aren’t about who should be used in a specific spot because the manager can be creative in the playoffs. The rankings below are about who is pitching well and who has the best stuff to succeed in October.
10. Sean Poppen (4.70 ERA, 1.70 WHIP, 10 K, 7 2/3 IP)
Poppen has seen limited time for the Twins this year and it seems unlikely that he would be called on in October. His lone role might be to eat some innings if there was a blowout. He also hasn’t pitched in a game in nearly two weeks. Twins fans don’t want to see him on the mound in the playoffs, because that likely means something went wrong in the game.
9. Caleb Thielbar (1.69 ERA, 1.31 WHIP, 20 K, 16 IP)
Thielbar has been a feel-good story for the Twins this season as his pitching performance certainly has matched a player that hasn’t pitching in the big leagues since 2015. If you take out his first appearance, he has a 0.66 ERA while holding batters to a .149/.259/.149 (.408) slash-line. Also, he has been asked to get more than three outs four of his fourteen games, which is likely something he wouldn’t be asked to do in the postseason. On other teams, he’d rank much higher.
8. Cody Stashak (3.09 ERA, 0.86 WHIP, 15 K, 11 2/3 IP)
Stashak has been really good and him being this low shows the depth of the Twins bullpen. He’s only allowed runs in two of his nine appearances and he has multiple strikeouts in over half of his outings. His one bad appearance was an inning where he allowed three runs to Kansas City. Rocco Baldelli has shown faith in using him in the late innings of close games. With few off days in each series, Stashak might be needed for some big outs.
7. Jorge Alcala (2.91 ERA, 1.20 WHIP, 27 K, 21 2/3 IP)
Alcala might have helped Twins fans to forget about Brusdar Graterol since he is basically filling the same role on the team. He’s also been better than Graterol this season. His fastball will certainly play in October and he’s used his slider nearly as often. His Baseball Savant page is also the thing of dreams as he ranks as ranks higher than the 80th percentile in all but one category. He could be the team’s closer of the future and October could be his month to shine on the big stage.
6. Matt Wisler (1.11 ERA, 1.03 WHIP, 34 K, 24 1/3 IP)
Wilser has been the Twins diamond in the rough this year. Claimed off waivers, the Twins have helped him to morph into one of the American League’s best relief pitchers. According to Baseball Reference, he is tied with Jose Berrios for the fourth highest WAR on the team behind Byron Buxton, Kenta Maeda, and Nelson Cruz. He’s been used as an opener, earned a save, and has five holds to his name. His versatility could be useful with how effective he continues to be.
5. Tyler Clippard (2.78 ERA, 0.93 WHIP, 22 K, 22 2/3 IP)
Minnesota saw plenty of Clippard last year in Cleveland and he’s been nearly as good so far this year. He could actually move down this list with some recent poor performances. In three of his last four appearances, runs have been scored against him, so his worst stretch of the season might be coming at the wrong time. Baldelli will likely continue to turn to him because he is a 14-year veteran with 14 playoff appearances during his career.
4. Sergio Romo (2.89 ERA, 0.91 WHIP, 22 K, 18 2/3 IP)
Since the Twins acquired him last year, Romo has been getting plenty of late inning opportunities out of the Twins bullpen. Taylor Rogers has struggled at times this year and this has led the Twins to continue to use Romo in late inning situations. Fans saw this as recently as Sunday night in Chicago with Rogers getting the eighth and Romo getting the ninth. Things got a little shaky in that game, but he has a long playoff track record and he’s going to be trusted to get outs in the eighth and ninth inning.
3. Taylor Rogers (4.58 ERA, 1.53 WHIP, 22 K, 17 2/3 IP)
Rogers and his struggles have been well documented throughout this season. In such a small sample size, luck might be accounting for some of his poor performance. His BABIP is one of the highest among all relief pitchers and his 4.58 ERA comes with a 2.84 FIP. Some of his issues this year might also be tied to the use of his breaking pitches. As Nick wrote about last week, his curve spin rate has flattened out and this could be one reason for more solid contact against him. Whether it’s luck or a poor breaking ball, the Twins need Rogers to be in peak form by the start of next week.
2. Trevor May (4.35 ERA, 1.16 WHIP, 34 K, 20 2/3 IP)
Back on September 6, May blew up in a loss to Detroit as he allowed three runs on four hits and saw his ERA rise to 5.74. In his last five appearances, he has been nearly unhittable with opponents limited to two hits, both singles. He has struck out eight in five innings and nearly 60% of his WPA for the season has come during this recent stretch. Even though his season hasn’t been perfect, he’s been Minnesota’s hottest reliever to end the season.
1. Tyler Duffey (1.69 ERA, 0.80 WHIP, 28 K, 21 1/3 IP)
Duffey is the Twins best relief pitcher and it might not be close. If an opponent’s heart of the line-up is coming up in a key spot, Duffey gets the call in the bullpen. These types of situations will only be more amplified in the upcoming postseason. So far this season, he has pitched in any inning from the fourth to the eighth, because Baldelli trusts him in any situation. He isn’t the Twins closer, because he is better than any of the closing options for the Twins.
