Derek Jeter leads MLB in ground ball percentage, ranks 188th in slugging percentage

Derek Jeter quickly ditching the “new swing” he worked on with hitting coach Kevin Long hasn’t helped his production, as the Yankees shortstop is batting just .219 with a .282 on-base percentage and .234 slugging percentage in 16 games.

Jeter is still doing a fine job controlling the strike zone, drawing six walks compared to just five strikeouts, but he’s managed a grand total of one extra-base hit (a double against the Twins on April 7) in 64 at-bats.

And there’s a simple explanation for Jeter’s lack of pop: He’s hitting everything on the ground.

Jeter has never been a slugger and has always been a ground-ball hitter, but prior to this season he averaged 55 extra-base hits per 160 games for his career and his ground-ball rates have never been this extreme. Not only does he lead MLB in ground-ball percentage at 72.9, second-place Alcides Escobar of the Royals is at 68.5 percent and no one else in either league above 65.5 percent.

Here are Jeter’s ground-ball percentages for the past five seasons:

YEAR      GB%
2007     56.1
2008     58.3
2009     57.0
2010     65.7
2011     72.9

Not only is 72.9 percent ground balls by far a career-high for Jeter, last year’s mark of 65.7 percent is the only other time he’s topped 60 percent grounders. There are plenty of very successful hitters with high ground-ball rates, with Jeter and Ichiro Suzuki being the leading examples, but there’s a big difference between hitting 55-60 percent ground balls and hitting 70 percent ground balls.

His batting average is going to rise from .219, but if Jeter doesn’t start hitting the ball in the air he’s going to have a very hard time avoiding a sub-.400 slugging percentage for the second straight season after topping .400 in 15 consecutive years. In his 145 most recent games dating back to May of last season Jeter has hit .257 with six homers, 25 doubles, and a .336 slugging percentage.

Mariners’ right-hander Felix Hernandez is looking at a 3-4 week recovery period, the team announced on Friday. Hernandez has been officially diagnosed with bursitis in his right shoulder after getting pulled from his last start against the Tigers on Tuesday.

It’s not the first shoulder issue the 31-year-old righty has dealt with during his career. Ryan Divish of the Seattle Times notes that Hernandez was previously diagnosed with bursitis during a minor league stint in 2005, several weeks prior to making his major league start for Seattle. This time around, however, the injury is coupled with a few years of not-so-sharp stuff, waning velocity and career-low numbers, and while it’s certainly not a worst-case diagnosis, it seems like greater cause for concern.

Without Felix, the Mariners will keep rolling with James Paxton, Hisashi Iwakuma, Ariel Miranda, Yovani Gallardo and Chase De Jong in their rotation. They’ll also keep Ben Gamel in right field, with starting right fielder Mitch Haniger expected to miss 3-4 weeks after sustaining a Grade 2 strain in his right oblique on Tuesday.

The Rays acquired minor league reliever Drew Smith from the Tigers on Friday, per a team announcement. The move will close the loop on the trade the two teams began in January for backup outfielder Mikie Mahtook.

Smith, 23, pitched his first full season in Single-A West Michigan in 2016, turning in a 2.96 ERA, 4.3 BB/9 and 11.5 SO/9 in 48 2/3 innings. The right-hander is still several levels away from making any impact on the Rays’ major league roster, but appears to be progressing steadily in two seasons of pro ball and has delivered two runs, four walks and 12 strikeouts in his first 11 2/3 innings at High-A Lakeland this season. Marc Topkin of the Tampa Bay Times reports that he’ll be reassigned to the Rays’ High-A Charlotte this week.
