Here's what to watch for throughout the day (all times in ET):
Trout, Angels visit Boston: LAA@BOS, 7:10 p.m.
Trout will take the field today opposite the two outfielders he may start alongside at Petco Park next month in Boston's Bradley and Betts. In the latest All-Star balloting update, they ranked as the top three outfielders in the AL. On the mound, Wright will continue to make the case for his own inclusion in the Midsummer Classic. The knuckleballer leads the AL with a 2.18 ERA but is coming off a rough outing vs. the Rangers in which he surrendered seven hits and eight runs. The Angels will counter with right-hander Jhoulys Chacin, who has allowed four or more runs in each of his last four starts.
Stat that matters: Mike Trout is batting .373 with six doubles and a .930 OPS in 13 career games at Fenway Park, but he's never homered at the Boston ballpark.
Mets bats look to back deGrom vs. Cubs: CHC@NYM, 7:10 p.m.
Despite boasting one of the lowest ERAs among National League starters (2.67), deGrom has just three victories to show for it. The Mets righty hasn't won since April 30. The Mets have gone 21 consecutive innings without scoring a run while deGrom is pitching and they've scored just two over his last 35 frames.
"You want to support him," Mets infielder Kelly Johnson said. "Everybody knows about our pitching. You've got to score runs and give them just the confidence to go out there and throw their game, and not have to worry about that kind of thing. ... Hopefully, we can help support them a little better going forward."
The Cubs will send Jason Hammel to the mound. He's 0-3 with a 4.91 ERA in five career starts against New York and also took a loss vs. the Mets in Game 5 of last year's NLCS.
Stat that matters: deGrom will have to contend with a red-hot Kris Bryant, who's homered four times this week and is batting 9-for-19 (.474) in those four games.
Cueto takes the hill: SF@ARI, 9:40 p.m.
The first-place Giants open a three-game series against the division-rival D-backs today as Cueto looks to rebound from surrendering six earned runs to the Phillies on Sunday. The D-backs are responsible for Cueto's lone loss this season, even though he yielded just three runs over seven innings of work. For Arizona, Shelby Miller will get the start. He hasn't fared well at Chase Field since joining the D-backs, going winless (0-5) with a 6.97 ERA at home this year.
Stat that matters: Giants batters have struck out just 293 times through 1,966 plate appearances against right-handed pitchers this season (14.9 percent), which ranks first among all MLB clubs.
