Newman entered Monday's game after Christian Walker (oblique) was removed following the third inning and went 2-for-3 with a double and an RBI in a 9-8 win over Washington.

EDGE Analysis

Walker is set to undergo an MRI on Tuesday to determine the extent of the injury, which could lead to steadier playing time for Newman. The utility infielder was a common feature in Arizona's lineup earlier in the season, but his playing time dried up when Geraldo Perdomo came off the injured list in June. If Walker's injury requires significant downtime, the Diamondbacks could make a move to add a player with more familiarity at first base than Newman, who has 10 games of experience at the position during his MLB career.
