Dillon Gee vs. Jonathon Niese: Who Should Be Traded?

I love watching Dillon Gee pitch.  Similarly, I am a fan of Jonathon Niese.

Although the Mets have been under .500 every season Gee has pitched in the majors, Gee himself has a won-loss record that is six games over .500 and he has never been more than one game under the break-even mark over a full season.  Jonathon Niese, on the other hand, is one of the few Mets left on the team who played at Shea Stadium (David Wright, Daniel Murphy and Bobby Parnell are the others, although Murphy and Parnell may not be on this list much longer).  Niese is also the team's only southpaw on a staff filled with right-handed pitchers.

As much as I enjoy having Gee and Niese on the team, I understand that the starting rotation currently has Bartolo Colon, Matt Harvey, Zack Wheeler and Jacob deGrom taking up four spots, with Noah Syndergaard waiting in the wings.  Assuming Colon is traded at some point during the 2015 season (if not sooner), Syndergaard would be the obvious choice to replace him in the rotation.  That would leave one of the members of the Gee-Niese duo out of luck and perhaps out of a job in New York.

Knowing full well that either Gee or Niese will not be a Met by this time next year, I decided to see which player the Mets would be better off keeping.  One or both pitchers might be traded if the right deal comes along, but I think one of the two would be better off staying in the Mets' starting rotation.  Here's my reasoning for the player I would like to stick around.

Although he has a 3.91 ERA for his career, Dillon Gee has had only one full season in the majors in which he posted an ERA under 4.00.  Advanced metrics also have his lifetime FIP (Fielding Independent Pitching) at 4.23.  For all you kids out there, FIP measures how effective a pitcher is at limiting home runs, walks and hit batsmen while causing strikeouts.  Basically, those are the four categories in which fielders do not determine an outcome.  Therefore, Gee's 4.23 FIP is considered a little higher than what is expected from an average pitcher.

Jonathon Niese has a 3.87 career ERA, but has posted a sub-4.00 ERA in each of his last three seasons, going under 3.50 in two of the last three campaigns.  But on the FIP side, Niese has a lifetime 3.72 FIP and has posted a FIP under 4.00 in each of his last four seasons.  Niese has walked more batters than Gee, but has hit fewer batters and allowed fewer home runs per nine innings than Gee.  And when it comes to strikeouts, Niese is far superior to Gee, as Niese has surpassed 130 strikeouts in a season four times, while Gee has done it just once.

Speaking of strikeouts, although Niese is just 28 years old (he's actually six months younger than Dillon Gee), he's already in the Mets' all-time top ten in career strikeouts.  Niese's 713 Ks are tenth on the team's lifetime leaderboard and he is just one strikeout behind Bobby Jones for ninth place.  Once he passes Jones, the only pitchers in front of him will be Tom Seaver, Dwight Gooden, Jerry Koosman, Sid Fernandez, David Cone, Ron Darling, Al Leiter and Jon Matlack.  You may also know that octet as arguably the eight best pitchers in the history of the franchise.   Niese's strikeout-to-walk ratio (2.69; 713 K/265 BB) is also far better than Gee's ratio (2.26; 464 K/205 BB).

Let's look at another new metric to determine a pitcher's effectiveness - ERA+.  This metric compares a pitcher's earned run average to the league average and also accounts for park factors, with 100 being considered an average ERA+.  For example, Citi Field is generally considered a pitcher's park.  However, Dillon Gee has never posted an ERA+ of 100 in any of his four full seasons.  From 2011 to 2014, Gee has posted a 90 ERA+, with a career-best 98 ERA+ in 2013, which is still 2% worse than the average pitcher.  Meanwhile, Jonathon Niese has a 97 ERA+ since he became a regular in the rotation in 2010.  But since 2012, Niese has a 104 ERA+, making him 4% better than the average pitcher over the last three seasons.  Niese's career-best performance in this metric came in 2012, when he posted a 112 ERA+.

WAR (wins above replacement) is all the rage in this sabermetric era of baseball.  The higher the WAR, the better the player.  It's that simple.  Looking at the WAR posted by Gee and Niese since 2011 (the year both pitchers were rotation-mates for the first time), it's clear which pitcher has been more valuable to the team.  Gee has a 4.5 WAR since 2011, going above 1.0 just once in the four years (2013, when he posted a 2.2 WAR).  In the same time period, Niese has a 6.2 WAR, posting a 3.4 WAR in 2012 and a 1.7 WAR this past season.

WAR.  What is it good for?  For Niese, it might be good for keeping him in New York.  (Brad Penner/USA Today Sports)

Finally, let's look at one overlooked, but still important, part of the pitcher's game - his offense.  When a pitcher comes to bat, he's not expected to do much.  If there's a runner on base, he's expected to bunt him over.  If there's no one on base, the best a pitcher is expected to do is not get hurt swinging the bat and maybe make the opposing pitcher throw a few extra pitches.  When it comes to proficiency with the bat, there's no contest between Gee and Niese.

Since becoming a regular in the rotation in 2011, Dillon Gee has a .154 on-base percentage, reaching base 27 times (18 hits, nine walks) in 206 plate appearances.  Meanwhile, since Niese joined the rotation for good in 2010, he has reached base an incredible 66 times (38 hits, 28 walks) in 304 plate appearances, which is a .237 on-base percentage.  Of all pitchers with at least 200 plate appearances since 2010, only Zack Greinke (.274 OBP in 245 PA) and Mike Leake (.261 OBP in 338 PA) have a higher on-base percentage than Jonathon Niese and only Ian Kennedy has drawn more walks (32 BB in 342 PA) than Niese.  Kennedy and Niese are the only pitchers who have walked more than 20 times since 2010.

So let's review.  Jonathon Niese has a better ERA, ERA+, FIP and WAR than Dillon Gee.  Niese is also much more adept at recording strikeouts than Gee and has a better K/BB ratio.  And while Gee is almost an automatic out with the bat, Niese gives the Mets a ninth hitter in the lineup, reaching base just under a quarter of the time.  Niese isn't going to break into a home run trot any time soon, but he has proven to be one of the better handlers of the bat among National League pitchers.

Dillon Gee will blow out 29 candles during the first month of the 2015 campaign.  Jonathon Niese will be 28 all season.  Niese has more experience than Gee, having pitched at Shea Stadium.  Niese is also left-handed, something no other starting pitcher on the Mets can claim.  Although Gee is still arbitration eligible and will likely not command more than $5 million in 2015, Niese is due $7 million in 2015 and $9 million in 2016, hardly amounts that would break the Wilpon family piggy bank.

If the Mets are going to trade one of their veteran homegrown pitchers before the curtains rise on the 2015 season, it should be clear which one should go.  Although I've always enjoyed watching him pitch and still believe he can be successful in New York, Dillon Gee will probably be the victim of an overcrowded starting rotation.  Jonathon Niese, despite all the question marks surrounding his health, has still made at least 24 starts in each of his five full seasons in the majors.  Gee has surpassed 22 starts just twice in his four full seasons with the Mets.  Also, Niese may not always utter the most politically correct statements, especially when it comes to Mets fans' loyalty, but you can't say he was pulling things out of his posterior.  If the Mets are going to draw the crowds Niese was used to seeing when he was a neophyte, then the team has to play better.  And right now, I believe the team will perform better with Niese on the team instead of Gee.

Of course, trading Gee or Niese will depend on the package the Mets would receive in return, but if each package was similar and the Mets had an option of trading either player, then that player should be Gee.  The future of the team would look a lot brighter if it held on to Niese.

Fool's Gold For Juan Lagares

Earlier today, Rawlings announced their nominees for this year's Gold Glove Awards at each position.  Two Mets were nominated for the prestigious defensive excellence award.  Two-time winner David Wright will compete with Colorado's Nolan Arenado and Los Angeles' Juan Uribe for the prize at third base, while Eric Young, Jr. will go up against fellow left field nominees Carlos Gonzalez (Rockies) and Starling Marte (Pittsburgh).

But perhaps the Mets' best defensive player was mysteriously left off the list of nominees.  Hey, Rawlings!  Where in the world is Juan Lagares?

One of these Mets outfielders was nominated for a Gold Glove Award.  It's not the one you think.

The three finalists for the Gold Glove in center field are Carlos Gomez of the Milwaukee Brewers, Andrew McCutchen of the Pittsburgh Pirates and Denard Span of the Washington Nationals - all worthy candidates.  But Juan Lagares may have the better defensive numbers, especially when considering the sabermetric stats, which are now part of the voting process.

Juan Lagares was second in the league behind Gomez with 26 defensive runs saved (DRS).  Meanwhile, McCutchen and Span combined to save just ten runs defensively.  (A.J. Pollock saved 15 runs for the Diamondbacks in center field and he was also snubbed as a nominee.)

Another stat used to measure a player's defensive value is UZR (ultimate zone rating).  Once again, Gomez led the league in that category with a 24.4 UZR, just slightly ahead of Lagares, who posted a 21.5 UZR.  And yup, McCutchen and Span together couldn't match what Lagares produced, as their UZR added up to 17.1.

Have you ever heard of ARM?  That's another sabermetric stat which measures the amount of runs above average an outfielder saves with his arm by preventing the advancement of base runners.  (This factors into the calculation of UZR.)  In common English, it shows how much opposing runners are afraid of running on an outfielder's arm.  Juan Lagares had a 12.3 ARM.  The three center field Gold Glove nominees (Gomez, McCutchen, Span) combined for a 9.0 ARM.

What else did Juan Lagares lead the league in?  Let's see.  There was Range Factor/9Inn, which measures putouts and assists per nine innings.  Lagares led the league with a 2.98 Range Factor/9Inn as a centerfielder.  He also led all outfielders, regardless of position, in that category.  There was also that handy, dandy assists thing.  Lagares led all centerfielders with 14 outfield assists, and added another one as a rightfielder.  His 15 total assists set a new Mets rookie record.

Not bad for a player who didn't become the team's regular centerfielder until the Rick Ankiel experiment was deemed a failure in early June.

I don't disagree that Carlos Gomez, Andrew McCutchen and Denard Span are all excellent defensive players.  But how can a list of the top three centerfielders in the National League in 2013 not include Juan Lagares?  The kid will win a Gold Glove or ten before his career is over.  He should have been considered for his first this year.

Hakuna Tejada! What A Wonderful Day!


Rejoice, all you Ruben Tejada lovers!  Your beloved shortstop is back!

The Mets' Opening Day shortstop has been activated from the disabled list (as was relief pitcher Ramon Ramirez) after being sidelined for the past seven weeks with a thigh injury.  Infielder Jordany Valdespin will be leaving 'Spin Citi to return to AAA-Buffalo to make room for Tejada on the active roster.

Tejada will be the starting shortstop and will bat second in tonight's rubber match against the Yankees, according to the Mets' official Twitter account.


Since Tejada was injured on May 6, the Mets have started four different players at shortstop, with Omar Quintanilla (21 games), Ronny Cedeño (16 games), Justin Turner (6 games) and the recently-demoted Jordany Valdespin (1 game) all taking turns keeping the position warm for Tejada's eventual return.

That return will come tonight.  Prior to his injury, Tejada was hitting .305 with ten doubles in 27 games, all while playing a smooth shortstop (only two errors in 111 chances).  Sabermetricians will also be quick to point out that Tejada is one of only two Mets this year (David Wright is the other) to rank in the team's top five in offensive WAR (0.9, 4th on the team) and defensive WAR (0.3, 3rd on the team).  For those not into the advanced metrics, that's pretty darn good.

Hakuna Tejada!  Ruben is back, well-rested and (hopefully) fully recovered from his thigh injury and embarrassing face plant that kept him on the sidelines since early May.  His presence in the lineup and on the field can only help the Mets as they try to continue their improbable run to the top of the division.
