A few days ago, we checked in on what to believe and what not to in the National League. Well, the American League is perhaps even more chaotic.

The New York Yankees and Boston Red Sox are in the midst of a crucial four-game series at Yankee Stadium — with the final game on “Sunday Night Baseball” at 7 p.m. ET on ESPN. Both teams will try to make a statement and inch closer to the Toronto Blue Jays at the top of the division while staying ahead in the wild-card race.

The Blue Jays had been hot — except they just lost a series to the lowly Pittsburgh Pirates. The Houston Astros were recently shut out three games in a row (and four out of five) but kept their slim hold on first place in the AL West because the Seattle Mariners went 2-7 on a recent road trip, including a brutal three-game wipeout in Philadelphia. Meanwhile, the Detroit Tigers might be back on track, and the Kansas City Royals are suddenly surging.

Let’s check on the current states of overreaction in the AL and make some verdicts.

Overreaction: Judge! Bellinger! Stanton! The Yankees are back, baby!

Calm down there, tiger. The Yankees took two of three from Minnesota. They scored 24 runs in sweeping St. Louis, and then they bashed nine home runs in a win over Tampa Bay.

The middle of the order is leading the way. Aaron Judge is back off the injured list. Cody Bellinger has proven to be one of the most unheralded pickups of last offseason, on his way to his most home runs since his MVP season of 2019. The big shocker has been Giancarlo Stanton, though. He missed the first two-plus months of the season because of what was described as a double tennis elbow, as if he had spent the offseason working on his backhand slice, preparing for the French Open. In 46 games since returning in mid-June, he’s hitting .311/.389/..642, producing what is easily his highest OPS since his MVP season of 2017, and has been so hot that the Yankees played him a few games in right field to keep his bat in the lineup (allowing Judge to DH while working on returning to the field) even though Stanton is less mobile than the monuments in center field.

So, it has been a nice stretch after losing records in June and July. But there are still issues. Max Fried, who starts Friday night, is scuffling, with a 6.80 ERA over his past eight starts. He hasn’t had a quality start since June. The back of the bullpen is still sorting out things, as David Bednar has replaced Devin Williams as the closer (and blew the save Wednesday, although the Yankees won in extra innings), but Camilo Doval and Jake Bird, two other trade deadline acquisitions, haven’t made an impact. There could still be a terrific bullpen here, especially if Williams gets straightened out, but let’s hold off on declaring that.

And Judge still hasn’t played the outfield. Though manager Aaron Boone played Stanton in right field at Yankee Stadium, where there is less ground to cover, he hasn’t played Stanton in the field on the road, leaving him as a part-time player for now. Ryan McMahon, the team’s other big deadline move, has been getting on base but has one home run in 22 games with the Yankees.

VERDICT: OVERREACTION. You can make the argument that if everything was clicking for the Yankees, they have the most upside and deepest roster in the AL: a potential ace in Fried, a potential No. 2 in Carlos Rodon, a potential wipeout bullpen, the best hitter in the sport in Judge and power up and down the lineup. They haven’t played that well against the top teams in the AL, however, including a combined 4-13 record against the Red Sox and Blue Jays, and Fried’s current struggles are a big concern. Let’s not put the Yankees in the playoffs yet.

Overreaction: The Red Sox have to win this series against the Yankees

The likeliest scenario in a four-game series between two evenly matched teams is, of course, a split. That would leave the Red Sox where they started the series, one game behind the Yankees and in third place in the AL East, but potentially in a much tighter wild-card picture. Still, after winning their first five games in August, the Red Sox went 3-7 in their past 10 games entering the Yankees series, so that makes this series a little more pressure-packed even for a late-August Red Sox-Yankees showdown.

Most frustrating, the Red Sox lost two games in extra innings in that 3-7 stretch and also lost both games that Garrett Crochet started. He had one bad start against the Houston Astros, lasting four innings in his worst start of the season, and then the bullpen blew a 3-1 lead to the Miami Marlins as Greg Weissert and Steven Matz allowed ninth-inning home runs when Aroldis Chapman was unavailable to close. Chapman had pitched the previous games and had thrown only 14 pitches over the two outings, so it was a dubious decision by manager Alex Cora (Chapman had appeared in three consecutive games earlier in the season).

One key for the Red Sox down the stretch: How much will Cora push his top pitchers? Crochet is already past his innings total of 2024 and hasn’t pitched on four days’ rest since June 18, with rest periods of seven and nine days during that span. Chapman has had a dominant season but has pitched just 48 innings in 53 appearances and has rarely made even back-to-back outings. The Yankees series begins a stretch for Boston of 13 games in 13 days and 19 in 20, so Cora will have to make some decisions with his rotation.

VERDICT: OVERREACTION. Is there urgency to turn things around? Of course. Is this a do-or-die series? No, it’s still too early to make that claim, especially with the Red Sox still in a solid wild-card position (granted, chasing down the Blue Jays remains the ultimate goal). On the other hand, this eight-game road trip to New York and Baltimore looms large, given the Red Sox are just 28-34 on the road– and the Orioles have been playing better of late. A bad road trip could be disastrous. Check back next week.

Overreaction: The Blue Jays — not the Tigers — are now the best team in the AL

The Blue Jays have gone 48-26 since May 28 — the second-best record in the majors behind Milwaukee since that date. They have the highest OPS in the majors since then and only the Brewers are close to them in runs scored (Boston has scored the third-most runs and is 50 runs behind the Blue Jays since May 28). It hasn’t been just Vladimir Guerrero Jr. and Bo Bichette either. George Springer and Addison Barger have mashed, Daulton Varsho has had a big August and role players such as Davis Schneider, Joey Loperfido, Ernie Clement and Tyler Heineman have been excellent. Toronto has a sneaky deep lineup.

Oh, and Max Scherzer has suddenly reeled off five straight quality starts.

On the other hand, the Tigers seem back on track after that stretch in July when they lost 11 of 12. They’ve won four series in a row, granted, three of those were against the Los Angeles Angels, Chicago White Sox and diminished Minnesota Twins, but they also just swept the Astros, knocking around Framber Valdez in the series finale Wednesday and tossing shutouts in the other two wins. Charlie Morton has helped stabilize the rotation with three excellent starts in his four turns with the Tigers, and the bullpen — with added reinforcements from the trade deadline — has been much better in August after struggling in July. Kerry Carpenter has also been mashing since his return in late July.

VERDICT: OVERREACTION. If you’re buying Scherzer and Eric Lauer as frontline starters and all the surprising offensive performances, then it’s not unreasonable to suggest the Blue Jays are the team to beat. Some of those offensive numbers are skewed by that crazy series at Coors Field when they scored 45 runs in three games, however, and when considering the entire season, the Tigers still have the better run differential (as do the Yankees and Red Sox). The Jays’ bandwagon is gaining momentum, but the AL still feels like one big group of teams that will all finish 92-70.

Overreaction: The Astros can’t hit, and the Mariners can’t pitch

Does anyone want to win the AL West? It doesn’t seem like it (you can even throw in the Texas Rangers, who were tied with the Mariners on July 30 but have gone 6-13 since then in playing a difficult August schedule). The Astros are hitting just .226 in August with a .649 OPS. Carlos Correa has been their best hitter, so it’s hard to criticize that trade, but Jesus Sanchez has hit .150 with one RBI for Houston while rookie Cam Smith has fallen into a slump. Getting back Yordan Alvarez, who just began a rehab assignment, will be a big lift if he’s healthy.

As for the Mariners, they have their top five starters healthy for the first time, but this road trip exposed their secret: Their rotation is vastly overrated. The Mariners are 26th in rotation ERA on the road. Bryan Woo is the only starter of those five with an ERA under 5.00 on the road. Logan Gilbert has a 2.22 ERA at home and 6.00 on the road. Luis Castillo‘s road OPS is nearly 300 points higher than it is at home. They pitch well at home because T-Mobile Park is such a pitcher-friendly park. The Mariners still have two road trips remaining: a nine-game trip to Cleveland, Tampa and Atlanta, and then a six-game trip to Kansas City and Houston.

VERDICT: NOT AN OVERREACTION. Both concerns are legitimate. The Astros’ offense hasn’t been terrible this season, but it rates as middle of the pack, and Correa is replacing the injured Isaac Paredes, so he’s not an upgrade. Seattle’s rotation struggles on the road — and lack of bullpen depth — are perhaps an even bigger concern. The season series is tied 5-5. FanGraphs projects a dead heat for the division title. The teams will meet once more in Houston during the second-to-last weekend of the regular season — and that series might decide the AL West.

Overreaction: The Royals will make the playoffs

As the Red Sox, Astros and Mariners have stumbled over the past 10 games, it opened the door for the Royals, who won five in a row and seven of eight to inch closer in the wild-card race (with Cleveland right there, as well). Bobby Witt Jr. is raking in August, Vinnie Pasquantino has been crushing home runs and, further proof of the unpredictability of the trade deadline, Mike Yastrzemski and Adam Frazier, two seemingly minor pickups, have been outstanding.

The Royals are doing this without Cole Ragans and Kris Bubic, but Noah Cameron continues to pitch well and fellow rookie Ryan Bergert, who came over in the Freddy Fermin trade, has delivered three good starts. Just like last year’s team, the Royals have that spark of optimism rising at the right time.

VERDICT: NOT AN OVERREACTION. We’ll learn more about the Royals with this weekend’s series in Detroit and then the rematch next weekend in Kansas City. Otherwise, however, their schedule is pretty soft the rest of the way, including a season-ending road trip to Anaheim and Sacramento against two teams that will be playing out the string. The vibes are good. The Royals will sneak in as a wild-card team.
