Alex Cora seemingly has pushed all the right buttons for the Boston Red Sox amid their historic start, but the first-year manager won’t take credit for one impressive feat that his team has accomplished. The Red Sox recorded their 19th win in April on Monday night against the Kansas City Royals — a new franchise record — thanks to an offensive outburst that included a grand slam off the bat of Xander Bogaerts. Boston now has six grand slams on the season, tied for the most in Major League Baseball history before May 1. The feat is impressive in its own right, but even more so considering Boston didn’t hit any grand slams last season.
