A look at what's happening all around the major leagues today:
OFF THE MATT
Mets ace Matt Harvey starts vs. Miami at Citi Field, trying to bounce back from the worst start of his young career. He gave up seven runs in four innings last weekend at Pittsburgh, prompting manager Terry Collins to say Harvey might be dealing with a ''dead arm'' issue.
MAY BE MORE
Nationals star Bryce Harper takes his power show to Cincinnati for a weekend series. Harper had already hit 13 home runs in May and has 28 RBIs this month.
James Shields hasn't lost in 10 starts since signing with the Padres as a free agent in February. He's 6-0, though his stats aren't dominating - he has a 3.75 ERA and has given up 15 home runs, most in the majors. The Pirates face Shields at Petco Park.
After losing a season-high four in a row, the AL champion Royals open a set at Wrigley Field. Edinson Volquez starts for the Royals, and is 7-0 lifetime against the Cubs.
NICE TO SEE YA
Paul Goldschmidt looks to keep up his big bopping against the Brewers when Arizona opens a series at Miller Park. He is a career .386 hitter against them, with five home runs and 15 RBIs in 29 career at-bats.
