Yankees MIDSEASON REPORTCARD

AT 62-33, the Yankees have the second-best record in baseball and are 4 ½ lengths back of the AL East-leading Red Sox, and if Boston continues to win 70 percent of its games, the Yankees will spend the rest of the season competing for one of the two wild-card spots.

Gleyber Torres and Miguel Andujar have been a lot more than pleasant surprises. Giancarlo Stanton has thrived despite having to learn two new positions, DH and left field. Aaron Judge has proven there was not a morsel of fluke about his rookie year. The bullpen, anchored by Aroldis Chapman, is the best in baseball.

And Aaron Boone has done well in his first 95 games as a manager at any level. Now for the flip side. Gary Sanchez was hitting .190 when he went on the DL on June 25. He is due back Friday for the first of three Subway Series games against the Mets at Yankee Stadium. First base hasn’t delivered the production needed from a corner-in-field spot. The rotation, after Luis Severino and CC Sabathia, is suspect and in dire need of an upgrade before the July 31 nonwaiver trade deadline.

Here are The Post’s grades:

Luis Severino: A

Finished third in last year’s AL Cy Young voting and is in the discussion for the award this season. Working with a triple-digit fastball that remains live in the later innings and a wipeout slider, Severino is 14-2 with a 2.31 ERA in 20 starts. Not even two pedestrian outings before the All-Star break can dull what he has done.

Aroldis Chapman: A

Nobody better in baseball than the gas-throwing left-hander who has been battling a balky left knee for a while, but has converted 26-of-27 save chances and used a triple-digit fastball to record 68 strikeouts against 17 hits in 40 innings.

Dellin Betances: A

Got off to a slow start as he battled with control issues. From June 1 to July 14, however, the four-time All Star (he should have made it five straight this season) worked in 19 games, allowed five hits and one earned run in 18 ¹/3 innings (0.49 ERA), adding 32 strikeouts. He has been the perfect setup arm for Chapman, with a leg-locking breaking ball and a high-octane fastball.

Chad Green: A

Introduced himself last year as a big weapon out of the bullpen who could be used at any time of the game. Nothing has changed and Boone can use him in the sixth or later. In 36 appearances, the righthander the Yankees stole from the Tigers has allowed 38 hits and struck out 57.

David Robertson: A

Veteran right-hander can work anywhere Boone needs him and isn’t limited to oneinning appearances. Former closer put his ego away last year after rejoining the Yankees from the White Sox and is 7-3 with a 3.09 ERA in a staff-leading 43 games in which he has allowed 28 hits and struck out 53 in 43 2/3 innings.

Aaron Judge: A

Already viewed as one of the best players in the game, the powerful mountain of muscle has become the Yankees’ leading man with 25 homers, 60 RBIs and a .936 OPS. The 132 strikeouts are cost of doing business.

Giancarlo Stanton: A

Only ignorant Yankees fans don’t appreciate what Stanton has accomplished three-plus months inside the pressure cooker that is New York. A right fielder for his entire career, he has been used as the DH and left fielder and has 23 homers, 55 RBIs and a .846 OPS.

Austin Romine: A

There are voices who believe he is the best backup catcher in baseball. Based on the way he has filled in for Sanchez this year, that argument has gained fuel. Pitchers enjoy throwing to him and his arm is just a tick behind Sanchez’s. A .270 batting average goes with 24 RBIs in 40 games.

Miguel Andujar: B

Came into spring training behind Brandon Drury and ticketed for Triple-A. That changed when Drury suffered from migraine headaches and blurry vision. Summoned in early May, Andujar has hit .279 with 12 homers, 39 RBIs and 27 doubles. Defense needs improvement but far from the nightmare some predicted.

Didi Gregorius: B

An out-of-this-world April turned into a miserable May at the plate, though he rebounded in June and July. Defensively, he never took the bat into the field where he is as good as any other shortstop in the AL. A .263 average, 17 homers and 52 RBIs combined with Gold Glove-caliber defense was good enough for the Yankees to keep him at short and pass on Manny Machado.

Jonathan Holder: B

Since returning from Triple-A on April 21, the right-hander has developed into a valuable bullpen weapon who can be used for length and at any juncture of the game. In 33 appearances, Holder has posted a 1.83 ERA overall. Since he came back to the big leagues, Holder has worked in 30 games and posted a 0.50 ERA.

CC Sabathia: B

Veteran lefty continues to be an effective starter who can be counted on to keep the Yankees in games with location and smarts. He is 6-4 with a 3.51 ERA in 18 starts. What numbers can’t tell is how other pitchers and players look up to him.

Adam Warren: B

Missed three-plus weeks with a strained back muscle but is a dependable reliever who can provide length. With 29 strikeouts and 21 hits in 24 ¹/3 innings the veteran right-hander fits very well into the elite bullpen.

Brett Gardner: B

Longest-tenured Yankee is valued far more than a .254 batting average would indicate. Leadoff hitter has a .345 on-base percentage due to 43 walks, which is second best on the club. Gardner is a center fielder playing left very well.

Aaron Hicks: B

The switch-hitting center fielder can be streaky, but when hot he adds length to the lineup, whether hitting leadoff against lefties or down the order versus righties. Has a .348 on-base percentage combined with 16 homers and 44 RBIs.

Masahiro Tanaka: C

Limited to 15 starts due to a DL stint, Tanaka’s 7-2 record looks better than his 4.54 ERA. Has been bitten by the home run (18 allowed).

Greg Bird: C

Missed the first six weeks due to ankle surgery and struggled when activated from the DL. The All-Star break arrived with the left-handed hitting first baseman in his first solid groove of the season. In the past seven games Bird is hitting .269 with three homers and 12 RBIs.

Gary Sanchez: C

Expected to be the Yankees’ most complete hitter, the catcher was hitting .190 with 14 homers and 41 RBIs in 63 games when he went on the DL in late June with a groin injury. Defensively, his nine passed balls are second among AL catchers and 34 wild pitches allowed are third. Needs to play better at the plate and behind it if the Yankees are to catch the Red Sox.

Neil Walker: D

Everyday player for most of a productive big league career, Torres’ arrival turned him into a bench player who can play first, second and third. Professional attitude is appreciated but at some point his roster spot could be in jeopardy.

Domingo German: D

After taking Jordan Montgomery’s spot in the rotation on May 6, the righthander has impressed at times and at others looked like his big league role is as a long reliever. In 18 games (12 starts) the right-hander is 2-5 with a 5.49 ERA.

Chasen Shreve: D

Only lefty in the pen beside Chapman, Shreve has been better lately. Split-finger fastball makes him a choice against righties as well as lefties. A 4.54 ERA should be better.

Aaron Boone: A

Easy-going nature and terrific people skills have worked so far. Talent has a lot to do with the team’s success, but out of all the candidates the Yankees interviewed to replace Joe Girardi, it’s not likely any could have done a better job.

Brian Cashman: A

Less than a month into the season, the GM believed Torres was ready for the big leagues and the rookie second baseman made Cashman look good. Trading for Drury early in spring training was a good move that still might turn out OK.
