FanGraphs Power Rankings: April 17–23

It was a week of highs and lows as the Rays continued to dominate early this season while the A’s took their first of many steps out of Oakland. Just a reminder that because we’re still so early in the season, we’ll see some pretty wild swings in the rankings below as teams continue to sort themselves out.

A reminder for how these rankings are calculated: first, we take the three most important components of a team — their offense (wRC+), their pitching (a 50/50 blend of FIP- and RA9-, weighted by starter and reliever IP share), and their defense (RAA) — and combine them to create an overall team quality metric. I also add in a factor for “luck,” adjusting a team’s win percentage based on expected win-loss record. The result is a power ranking, which is then presented in tiers below.

The Rays continued their hot start to the season, winning five of their six games last week; they still haven’t lost a game at home this year. The amount of depth on their roster means that even when their fantastic middle infield duo, Wander Franco and Brandon Lowe, starts to struggle — they collected just six hits between them last week — there’s someone like Harold Ramírez hitting instead (nine hits, two home runs). They’ll face a tough challenge in a surging Astros ballclub this week.

The Rangers vaulted themselves into this top tier by beating up on the Royals and A’s last week. So far, they’ve weathered the loss of Corey Seager to a hamstring injury behind the hot bats of Marcus Semien, Adolis García, and Jonah Heim. They’re also getting plenty of help from their pitching staff. Their rotation is fully healthy; Jacob deGrom had an injury scare on Monday after leaving his start after just four innings with a wrist issue but looked dominant against the A’s. But the biggest surprise has been their bullpen, which has the third-lowest ERA in the majors.

It’s shocking to see three NL Central clubs in this tier but not the Cardinals. The hot starts of the Brewers, Cubs, and Pirates are backed up by the underlying data: All three teams are hitting well, pitching well, and possess a run differential of at least +25. Cody Bellinger exacted some revenge against his former team, blasting two home runs off Dodgers pitching over the weekend, and Drew Smyly came within six outs of throwing a perfect game against Los Angeles on Friday.

While the Cubs and Brewers have looked impressive, the Pirates are turning heads. They swept the Rockies in Colorado and the Reds at home, allowing no more than three runs in any of their seven games last week, and now sit atop the division. Led by David Bednar, their bullpen has been lights out, while their rotation has gotten breakout performances from Mitch Keller and Johan Oviedo. They’ve got a tough schedule ahead with dates against the Dodgers, Rays, and Blue Jays over the next two weeks. We’ll see if they’re up to the challenge.

The Astros seem to have broken out of their funk, winning two of three from the Blue Jays and sweeping the Braves in Atlanta last week. They’re still missing Jose Altuve, Michael Brantley, and Lance McCullers Jr., and José Abreu isn’t hitting for power, but they’ve had unexpected contributions up and down their lineup, like Mauricio Dubón, who is filling in for Altuve at second base admirably with a 108 wRC+ and solid defense. Houston’s next task: slow down the Rays this week.

The Mets just wrapped up a 7–3 West Coast road trip, sweeping the A’s, winning two of three from the Dodgers, and splitting four games with the Giants. Despite that successful California swing, they couldn’t avoid stepping on their own toes. Max Scherzer was ejected from his start on Thursday after violating the sticky stuff prohibitions and accepted his 10-game suspension despite maintaining his innocence, but his absence puts New York in a bit of a precarious position. The rotation is already missing Justin Verlander, Carlos Carrasco, and José Quintana; the team will need to call up someone to take Scherzer’s place for the next two weeks.

There was a fleeting glimpse of what the Angels could be on Sunday afternoon. Losing to the Royals 2–1 entering the sixth inning, Taylor Ward, Mike Trout, and Shohei Ohtani launched back-to-back-to-back home runs to put Los Angeles ahead for good. There’s been very little of that kind of offense for the Angels this year; Trout is crushing the ball like usual, but Ohtani has been much better on the mound than at the plate, and Ward had been mired in a slump. Hunter Renfroe has been very good too, but the rest of the lineup just hasn’t carried its weight, and now it’ll be without Logan O’Hoppe for multiple months after he injured his shoulder.

The Twins locked up the most impressive member of their major league-best starting rotation last Monday, signing Pablo López to a four-year deal. Alongside hot starts from Sonny Gray and Joe Ryan, they have enjoyed some phenomenal performances from their starters. Unfortunately, their offense has yet to start clicking despite a bounce back from Joey Gallo. Carlos Correa is off to a particularly slow start, and Byron Buxton hasn’t tapped into the prodigious power he displayed last year. They did just activate Jorge Polanco off the IL and Alex Kirilloff shouldn’t be far behind. Perhaps those two will provide the spark to build some distance in the AL Central standings.

After allowing seven runs in three innings, ballooning his ERA up to 10.26, the Diamondbacks designated Madison Bumgarner for assignment on Thursday. They’re eating the remaining $34 million owed to him over the next two years, but his deteriorating performance was too harmful to a team that’s looking to turn a corner this year. Arizona was leading the NL West for most of last week until losing three of four to the Padres over the weekend. Zac Gallen, though, is putting together another long scoreless streak, running it to 21.2 innings after his start on Friday night, and the D-Backs have got a number of young pitching prospects in the high minors they could call on to replace Bumgarner.

The Giants have struggled through a rough start to the season despite a decent run differential. A pair of walk-off losses in Detroit were unfortunate, and they’ve only won a single series this year. But they’re getting good performances from players like LaMonte Wade Jr. and Thairo Estrada, and Mitch Haniger, one of their key offseason acquisitions, is close to making his season debut. They also signed Logan Webb to a five-year extension last Friday, a significant vote of confidence in his ability to lead the pitching staff.

The vibes are rough on the South Side of Chicago. The White Sox haven’t won a series this year and were just swept by the Rays over the weekend, including two ugly walk-off losses. Things aren’t going to get any easier either with a trip to Toronto this week before another series against the Rays and then the Twins after that. With Tim Anderson and Yoán Moncada still on the IL, the offense has had trouble getting started, but Chicago’s biggest problem has been a pitching staff that’s allowed the second most runs in the American League.

It feels cruel to continue to highlight the woes of the Athletics in this space, but they’ve played historically bad baseball. To make matters even worse, their ownership group announced that it had signed a binding agreement to purchase land in Las Vegas for a new stadium. There’s still so much up in the air before the franchise packs its bags for the desert, but this is the first concrete step that owner John Fisher and president Dave Kaval have made toward moving the team away from Oakland. It’s a dark time to be an A’s fan.
