Neal Walker walked and stole second with Chad Moeller behind the plate. John Raynor singled to left, Aki Iwamura struck out and Jose Tabata walked to fill the bases.
Garrett Jones hit a sharp grounder to Garrett Atkins, who couldn't backhand the ball cleanly. He quickly retrieved it and flipped to first for the out as Walker scored.
Only fifteen of Arrieta's 26 pitches were strikes.
Blake Davis has reached second base on an error with no outs in the bottom of the fifth.
