Daniel Nava hit a grand slam into the Red Sox bullpen on the first pitch in his first major league plate appearance!

Nava is the fourth player in history to hit a grand slam in the first at-bat of his major league career. The only other player to do it on the first pitch is Kevin Kouzmanoff of the Padres, who went deep on September 2, 2006. 

Rip Repulski is the only other Red Sox player to hit a grand slam in his first plate appearance with the team (May 10, 1960 against the White Sox). ... Matsuzaka was placed on the disabled list shortly before the game with a right forearm strain. Atchison gets the start -- and left-handed reliever Dustin Richardson is on his way from Pawtucket.

The Red Sox are expected to call up Daniel Nava, a 27-year-old switch-hitting outfielder, for today's game. [And they do.] Josh Reddick was optioned to Pawtucket last night. Nava is batting .294/.364/.492 for Pawtucket this season. Mike Andrews of Sox Prospects calls Nava "one of the best offensive players in the system over the last three seasons, regularly surpassing expectations at every turn". He has been a few years older than his competition at each level, though. Andrews has a good Q&A with Nava here. And:

Baseball Reference lists June 12, 2001 as the day Gary Sheffield of the Dodgers became the first player in MLB history to hit a solo home run in a 1-0 game three times in a single season, but it should be included on May 12: April 2 (Opening Day) vs Milwaukee, May 7 vs Florida, May 12 (bottom of the 9th) vs Atlanta.
