The left fielder went 11-for-26 last week, notching two doubles, two triples, three home runs and eight RBIs on a seven-game road trip through Cleveland and Detroit. Boston went 5-2 on the week, scoring 14 runs on back-to-back days with the help of four-hit performances from Crawford in each.
"It's nice to get that award," said Crawford. "It shows you had a good week. You get awarded by MLB. I'm very grateful to receive that."
In the first of his four-knock games, on May 23, Crawford snapped a homerless streak of 97 at-bats with a fifth-inning solo shot against the Indians, his first since April 24. He finished 4-for-4 -- the first time he notched more than two hits in a game this season -- with three runs scored, two doubles, the home run and two RBIs in Boston's 14-2 win.
In a 14-1 win the next day, Crawford went 4-for-5 with two runs, two triples and three RBIs. The 29-year-old became just the second Red Sox hitter since 1990 -- Dustin Pedroia was the other, in 2008 -- to record consecutive four-hit performances.
No one had tripled twice in a game for the Red Sox in nearly two years.
Crawford hit just one home run in 44 games this season before hitting three last week.
Crawford got off to a rough start in Boston after signing a seven-year deal this offseason, but he started to find his stroke after he worked on his timing.
"I'm feeling a lot better," said Crawford. "I'm feeling a lot more comfortable at the plate. Things are slowing down for me a lot. I feel like it's definitely gotten better for me from the way I started off."
He previously received the AL weekly honor three times, most recently on June 21, 2010.
