Cutnpaste: - wOBA Calculator, Jenrry Mejia, Mets Manager, Wilmer Flores, and Sean Ratliff

wOBA Calculator:
I’m a big fan of Weighted On-Base Average, or wOBA. And if you love baseball statistics, chances are pretty good that you’ve heard of it, or have used it before.

But how do you calculate those darn coefficients? Well, you can get there in about five steps:

1. Find the run value of each event (i.e. linear weight values)

2. Add the run value of the out to all batting events.

3. Multiply the modified run values by the frequency of the event and divide the total sum by plate appearances (sans intentional walks)

4. Solve for the scale needed to match your desired rate (usually between 1.15-1.20).

5. Multiply each modified run value by the scale. - HBT

 Jenrry Mejia:

Right-hander Jenrry Mejia, who was shut down at the end of the regular season because of what was announced as a rhomboid strain of the right shoulder blade, is back pitching in game in his native Dominican Republic, ESPN's Enrique Rojas reports. Mejia already has pitched four innings in academy games in the country. He could enter the Dominican Winter League after Dec. 1. - ESPN  

Mets Manager:But is that what the Mets need right now? Consider the team that the manager is inheriting. The Mets are a mix of veterans who have underachieved - and maybe underworked - along with still-impressionable youngsters. One Mets official said that despite no big-ticket player joining the team this winter the team is not concerned with selling tickets with a manager this year because the plan is for more than one season. Still, who can get the kids to work and develop while also pushing and prodding - without losing - the veterans? Who can make Jose Reyes realize his potential? Who can get David Wright to be the leader? Who can get the most of Ike Davis and Josh Thole? - nj.com  

Wilmer Flores:

Opening Day Age: 19 - Estimated Peak WAR: 5.5 - Notes: Flores didn’t have a huge season at the plate but he spent much of the season playing A-ball at the age of 18. The right-handed hitter batted .278/.342/.433 in low-A and then moved up to high-A where he produced a line of .300/.324/.415. Flores was overly aggressive in high-A and saw his walk rate plummet from 7.5% at the lower level to 3.1%. His 36 doubles on the year hint at the raw power he possesses. His strikeout rates have been impressive (14.4% in high-A) given his age; hopefully he can maintain them as his power numbers spike. Flores hits with an open stance and is susceptible to balls on the outer half of the plate. He has a habit of pulling his head off of breaking balls. He also has a lot of movement in the hands, which he clearly uses as a timing mechanism. Flores is at his best when he maintains a level, line-drive stroke and avoids the upper cut. He has enough bat speed that he doesn’t need to generate loft by dropping the head of the bat. Look for his power numbers to spike when he buys into the approach. Flores doesn’t play with as much energy as you might expect from a top-of-the-line prospect and his lack of range will eventually move him off shortstop. He has good arm strength and could end up at third base or an outfield corner. - fangraphs
