BOSTON — The Red Sox’s newest father is ready to return to the diamond.

The Red Sox reinstated outfielder Jackie Bradley Jr. from paternity leave Friday ahead of Boston’s series opener against the Toronto Blue Jays at Fenway Park. He’ll get the start in center field and bat seventh.

The Red Sox optioned outfielder Rusney Castillo to Triple-A Pawtucket in a corresponding move.

It’s been a busy past few days for Bradley, who was named the American League’s Player of the Month for May on Thursday, the same day his wife, Erin, gave birth to their first child. The Red Sox had no trouble scoring in his absence, combining for 22 runs over their past three games, but went 1-2 in that stretch.

Bradley’s return bumps Chris Young out of the lineup, as Blake Swihart will get the start in left field and bat ninth.

Christian Vazquez will bat eighth and do the catching for Red Sox ace David Price, who is hoping to turn Boston’s pitching fortunes around after the club allowed 25 runs over its last two games. The Blue Jays will counter with knuckleballer R.A. Dickey.
