Top stats to know: Dodgers at Mets

The New York Mets host the Los Angeles Dodgers in Game 2 of a three-game set tonight (7 ET, ESPN). Here are some of the key storylines we will be following on "Wednesday Night Baseball."

Puig on a tear

Yasiel Puig has reached base safely in 21 consecutive games, the second-longest active streak in the majors behind Robinson Cano (27 games).

In that span, Puig is hitting .400, with 7 home runs, 26 RBIs and 12 walks.

Yasiel Puig – MLB Career

Puig’s improved plate discipline is a major difference between this season and last. He has lowered his chase percentage more than any player in the league, and that percentage has decreased in every month of his career.

As a result, his walk percentage has gone up and his strikeout percentage has decreased from 2013 to this season.

Ryu returns

Hyun-Jin Ryu returns to the Dodgers' rotation after missing more than three weeks with shoulder inflammation. Before his injury, Ryu had a strong start to the season, allowing zero runs in four of his first five starts, which is one behind Adam Wainwright for the most scoreless starts in the majors this season.

Lowest ERA by LHP
Since Start of Last Season

Ryu’s ERA in 2014 and for his career is 3.00, which is the fifth-best by a left-handed starter since the start of last season.

His arrival, coupled with the return of Clayton Kershaw last week, puts the Dodgers' rotation at full strength and takes some pressure off their bullpen, which has thrown 158 innings, the most of any National League team this season.

This has started to take its toll, as their bullpen ERA this month is 5.03, third-worst in the majors.

DeGrom follows debut

Jacob deGrom was a hard-luck loser in his MLB debut on May 15, allowing one run in seven innings against the Yankees. He was the first Mets starter to lose his major league debut despite allowing only one run since Ron Darling on Sept. 6, 1983, against the Phillies.

DeGrom, who played both third base and shortstop in college, singled in his first career plate appearance, becoming the first Mets pitcher to get a hit this season after they started 0-for-64, a modern-day record, according to the Elias Sports Bureau.

The rest of the Mets' pitching staff has yet to get a hit this season, going 0-for-71.
