The Diamondbacks reacted swiftly following Christian Walker’s injury on Monday night, acquiring first baseman Josh Bell from the Miami Marlins in a trade Tuesday morning.

The Diamondbacks are not giving up a player to get Bell but will be on the hook for $2.25 million of his remaining salary. He has roughly $5.5 million left on his $16.5 million salary this year.

Bell is in the midst of a mediocre year but has been swinging the bat well of late. He is 15 for 46 (.326) with six homers in his past 12 games, and he had a streak of four consecutive games with a home run come to an end on Sunday.

Walker exited Monday night’s game with left oblique tightness and underwent an MRI on Tuesday morning. According to a source, the Diamondbacks received a relatively encouraging report on his oblique; it is not considered a severe injury, but Walker is still expected to land on the injured list on Tuesday.
