Chavez hadn't played since Friday while dealing with a pinkie injury. He has hit .260/.284/.344 with one home run and 10 RBI in 154 at-bats.
The Rockies will almost assuredly pick up Hawkins' $2.25-million option if he can remain healthy throughout the season. While the Rockies appreciate his intangibles more than anything, he has converted 17 of his 18 save opportunities while posting a 3.09 ERA.
A Grade 3 strain is the most severe type of hamstring strain. The Nationals have yet to issue an official statement on the injury or on a timetable for Zimmerman's recovery.
"I've kind of on purpose not gone in to push him," manager Terry Francona said. "He's going to obviously add intensity as he continues to feel better. ... He will just continue to ramp up. And when he's ready to play, we'll send him out to play."
Bourn has been out since July 5 while recovering from a strained hamstring.
Robertson started the inning off with a strikeout, but a single, walk and sacrifice put two runners in scoring position with two outs. After the next batter walked to load the bases, Elvis Andrus delivered a two-run single. Robertson walked the bases loaded again but was able to retire the next batter to finish off the game. He owns a 2.88 ERA and 68:14 K:BB ratio in 40 2/3 innings.
Arencibia doubled in the second inning and then knocked in two runs with a double in the third. He homered in his next two at-bats, first hitting a solo shot in the fifth before slugging a grand slam in the seventh inning. He wrapped up his night by striking out to lead off the ninth. Arencibia owns a .183/.223/.404 line after Tuesday's out-of-nowhere explosion, and he has six home runs and 22 RBI in 104 at-bats.
McCarthy (6-10) has won three straight starts, but Tuesday's outing was his ugliest performance since joining the Yankees in early July. He owns a 4.56 ERA and 113:24 K:BB ratio in 134 1/3 innings. McCarthy is scheduled to face the Tigers Monday.
Martinez (1-7) gave up a first-inning solo home run but held a 4-1 lead after five innings. The Yankees offense caught fire in the sixth, scoring seven runs before the inning was up and tacking on a few more in the seventh. Martinez owns a 5.08 ERA and 34:35 K:BB ratio in 78 innings. He's scheduled to face the White Sox Monday.
"I've been feeling pretty good," Albers said. "I think I felt pretty good a couple of times and then when I got off the mound, I had a setback. Hopefully, this time we're making sure I stretch it out and get some extra throwing in before I get back off the mound, but it's feeling pretty good right now."
Albers added that he expects to throw at 70-75 percent intensity Friday in order not to push himself too hard as he attempts to return from a lengthy injury.
