A look at what's happening all around the major leagues today:
Mets catcher Travis d'Arnaud is hurting with a hyperextended left elbow. He was injured in a collision with Atlanta runner A.J. Pierzynski on Saturday night. D'Arnaud returned 10 days earlier from the disabled list after missing seven weeks with a broken right hand.
The Red Sox will see how Pablo Sandoval is feeling after he left a game because of a sprained left ankle. He hurt himself while making a team-high 10th error Saturday night at Kansas City.
Pirates righty Charlie Morton has won all five of his starts this year. He began the season on the disabled list while recovering from an injured hip, and has a 1.62 ERA going into his matchup with Gio Gonzalez at Nationals Park.
BURNING IT UP
Billy Burns has done quite well filling in for A's leadoff man Coco Crisp, who has missed much of the season with a variety of injuries. Burns leads AL rookies in hits and steals, and takes an 11-game hitting streak into the series finale vs. the visiting Angels.
Phillies lefty Adam Morgan will make his big league debut vs. St. Louis, filling in for injured Jerome Williams. Morgan was winless in 13 starts at Triple-A Lehigh Valley, going 0-6 with a 4.74 ERA.
HAPPY TO SEE YOU
Mariners lefty J.A. Happ has never lost a start against Houston, one of his former teams. He's 3-0 with a 3.48 ERA in five starts vs. the Astros, and is set to face them again at Safeco Field.
Cleveland second baseman Jason Kipnis has a 24-game hitting string at home. He hopes to extend it against Alex Colome and the Rays. Indians starter Cody Anderson will make his major league debut.
