APRIL BLOOMERS

WASHINGTON — Any Top 10 list of surprises for the first month of the baseball season had to start with Eric Thames. No-brainer, right? But then the Yankees rallied from eight runs down against the Orioles on Friday night, putting an exclamation point on their stunning April. Considering that teams in the majors were 1-317 when trailing by eight runs or more in a game over the last two seasons, yeah, that’s fairly surprising.

So what the heck, I’m putting them at the top of the list. The Yankees have turned into the fun story of this first month, in the rare season when expectations are fairly low for them.

And who knows, maybe having the best record in spring training wasn’t so meaningless, after all. Maybe having a bunch of veterans with a lot to prove, as well as some high-ceiling kids, is just the right mix.

Or it could just be a hot month. That’s the beauty of baseball: the truth will emerge over 162 games.

But if these Yankees turn this into a memorable season, those three games last week — the two wins in Fenway Park featuring dominant starts by Luis Severino and Masahiro Tanaka, and the crazy comeback on Friday night — might just be remembered as the launching point.

For now it simply makes them No. 1 on my list of Top 10 Surprises/Disappointments as the season heads into May.

1. YANKEES

Last year they finished 12th in the AL in runs scored, and 11th in home runs. If that was going to change this season, Gary Sanchez and Greg Bird were going to have to lead the way, right?

So here are the not-so-Baby Bombers, leading the AL in home runs, co-leading the league with the Mariners in runs scored, and Sanchez and Bird have barely been a factor.

Can it last? Starlin Castro and Chase Headley aren’t going to crush all year, but Sanchez and Bird are surely going to put up numbers at some point, and Aaron Judge looks like a force.

No less important, Severino has a 0.79 WHIP, 33 strikeouts against only four walks, and once again looks like a potential ace.

2. ERIC THAMES

You have to love that Thames addressed the PED speculation so openly last week, saying MLB can drug-test him all it wants. “I’ve got plenty of blood and urine,” he said with a smile.

Great story, coming back from playing in Korea, so let’s hope the guy is legit, and, in truth, the Cubs were way out of line for publicly speculating about it so soon. After all, eight of his 11 home runs before Saturday have been hit against the Reds, whose pitching is shaky at best.

3. AARON JUDGE

His at-bats have become the must-see events of the season, because you never know how far his next home run might go. Nobody in the majors is hitting the ball harder, on average, according to the MLB Statcast information, and while he has cut down on strikeouts from last year, what’s most impressive is how often he turns contact into long balls.

After he hit another home run on Saturday, 10 of his 22 hits are homers. As a result, his .767 slugging percentage was the highest in the AL. Also, the Yankees are 9-0 in games in which he has homered.

4. RYAN ZIMMERMAN

Coming off a dreadful season in which he hit .218 with a .648 OPS, and surrounded by speculation that injuries had diminished him at age 32, Zimmerman is off to a spectacular start, hitting .392 with 10 home runs and an eye-popping .861 slugging percentage through Friday.

As a righthander hitting between Bryce Harper and Daniel Murphy, he could make the Nationals a monster with a strong season.

5. BLUE JAYS

On the disappointment side, the Jays started 7-17, which was nine games out of first place and dwelling in the AL East cellar. They lost Edwin Encarnacion but nobody expected them to be punchless at the plate, second-tolast in the AL in runs scored.

Jose Bautista is hitting .167, Russell Martin .190, and Troy Tulowitzki and Josh Donaldson have been injured, as well as ace Aaron Sanchez. Also, the Jays gutted their farm system to go for it the last few years, so suddenly things look grim in Toronto.

6. EUGENIO SUAREZ

Who? Exactly. Actually, he’s had a couple of solid seasons at third base for the Reds, but this year he’s off to a hot start, with a 1.044 OPS. Plays good defense at third, so, for what it’s worth, the 25-year old Suarez is tied with Bryce Harper for highest WAR in the NL. Reds got him in a trade for Alfredo Simon three years ago.

7. METS

Maybe it’s starting to turn for them after two wins over the Nationals, but they still qualify as the most disappointing team in the NL. Everything has gone wrong: injuries, defense, bullpen, and most of all the offense with the .215 team batting average, worst in the majors entering Saturday. Starting pitching, however, offers hope for a turnaround.

Supposed to be the can’t-miss Rookie of the Year after hitting .302 in 38 games late last season, Swanson is hitting .134 for the Braves, looking so lost that an NL scout said of the young shortstop, “They need to send him down.”

9. MITCH HANIGER

Seemingly a throw-in by the Diamondbacks, along with Jean Segura in the trade with the Mariners for Tajuan Walker, Haniger looks like a steal. An excellent outfielder, he’s hitting .342, leading the league with a .442 onbase percentage.

10. WHITE SOX

Aren’t they supposed to be tanking? Instead they’re 13-9, leading the AL Central. And despite trading Chris Sale, their pitching staff is leading the league with a 2.93 ERA, getting strong starts from bargain pickups like Derek Holland and Miguel Gonzalez, as well as outstanding bullpen work. In addition, Avisail Garcia is leading the league in hitting with a .376 average.

FARM TIDINGS

More good news for the Yankees: two of their top pitching prospects, Chance Adams and Justus Sheffield, are off to strong starts for the Double-A Trenton Thunder.

Adams, last season’s breakout prospect, is 3-0 with a 0.82 ERA in four starts. Like last year, he is “overmatching hitters” with his fastball and his slider, according to a scout, allowing only 13 hits in 211⁄3 innings, while racking up 22 strikeouts.

The righthander’s only flaw has been his 10 walks.

Sheffield, the lefthander acquired in the Andrew Miller trade, is 1-0 with a 1.56 ERA in three starts. In 171⁄3 innings, he has allowed 11 hits, to go with 16 strikeouts. Walks have been his only issue as well, with 10.

ROCKIN’ ROBERTSON

Attention, shoppers: David Robertson is off to a blazing start for the White Sox, perhaps setting him up to be the top target among contenders looking for bullpen help at the trade deadline.

He probably won’t bring the type of haul the Yankees got for Aroldis Chapman and Andrew Miller last season, in part because he’s making $13 million this season and again in ‘18, but the rebuilding White Sox should be able to deal him for prospects.

Robertson, the former Yankee, has a 1.17 ERA through eight appearances. In 72⁄3 innings, he has allowed just three hits, to go with 13 strikeouts and three walks.

He looms as a potential answer at closer for the Nationals. Or, who knows, with the issues the Mets are having, they could be in the market for someone like him.

THOR FOULS OUT

Noah Syndergaard needs to understand that with stardom comes the responsibility of acting the part. He was out of line on Thursday in calling PR director Jay Horwitz over to his locker and giving him an earful for all to see because he didn’t like being approached by reporters about his biceps tendinitis. He’d spoken before the game about being scratched from his start, but it was unclear if he’d seen a doctor and had more information about it. If Syndergaard didn’t want to address it, fine. If he wanted to shout out, “Jay, get your minions out of here,” well, that’s immature but whatever. But to make a scene by then going off on Horwitz, the long-time PR man whom the players adore? Completely unacceptable.
