LEADING OFF

A look at what’s happening around the majors today: MANAGING EXPECTATIONS: Mets manager Mickey Callaway is on the hot seat as his slumping team returns home to play NL East rival Washington. New York (20-25) has lost five straight and was swept in three games at lowly Miami over the weekend, totaling only three hits in consecutive shutouts. The reeling Mets are 11-21 in their last 32 games. “I understand that everybody is disappointed — the fans, the ownership, myself, the team — because this is not who we are,” Callaway said.

VLAD AND VICTORIA: Bighitting rookie Vladimir Guerrero Jr. and the Toronto Blue Jays host Boston in an afternoon game on Victoria Day. The 20-year-old Guerrero has homered four times in his last six games — he didn’t homer in the first 13 games after making his debut in late April.

Red Sox lefty David Price (1-2, 3.75 ERA) is scheduled to come off the injured list and start. He’s been sidelined with elbow tendinitis since May 3.

ASTRO OUT: AL home run leader George Springer has stiffness in his lower back and won’t play when the Astros open a series at home against the White Sox. The outfielder made an early exit Sunday at Fenway Park when he felt tightness. Springer, who has 17 home runs, will be re-evaluated in Houston.

REMEMBER ME? An All-Star for the Cubs when they won the 2016 World Series, Jake Arrieta (4-4, 4.02 ERA) starts at Wrigley Field for the Philadelphia Phillies. Yu Darvish (2-3, 5.14) pitches for Chicago in the opener of a four-game series.

SEVENTH HEAVEN: Jake Odorizzi (6-2, 2.63 ERA) has won six straight starts for the AL Central-leading Twins, giving up a total of six earned runs during that span. Odorizzi will try to extend the streak when he pitches in Anaheim against the Angels.
