53 Christian Walker 1B

Walker was optioned to Triple-A Reno on Monday.

Walker will head back to the minors after a one-day stay in the majors. The 27-year-old went 1-for-1 with a stolen base and a run scored in his lone appearance (as a pinch hitter) with the big club. Braden Shipley was summoned from the minors in a corresponding roster move.

Walker was recalled from Triple-A Reno on Sunday, Zach Buchanan of The Athletic Arizona reports.

Walker will be utilized as a bench bat with the Diamondbacks for the time being as catcher Jeff Mathis is away from the team on paternity leave. Walker has collected two hits in his 16 at-bats with the big-league club this season. His stay in the majors could be short-lived.

The Diamondbacks optioned Walker to Triple-A Reno on Friday.

Walker was recalled from Reno on Tuesday with the placement of A.J. Pollock on the disabled list, but the return of Jake Lamb (shoulder) made it a short stay in the majors. The 27-year-old is 2-for-16 with 10 strikeouts with the Diamondbacks this season, but has not seen a legitimate opportunity, given he has made only one start.

Walker was optioned to Triple-A Reno following Wednesday's game.

In a corresponding move, the Diamondbacks activated Steven Souza (pectoral) from the 10-day DL. During 15 appearances with Arizona this season, Walker only started one game and went 2-for-15 with one home run and two RBI while striking out nine times. He will return to the Triple-A level and receive everyday at-bats moving forward.

Walker delivered a pinch-hit solo home run in the Diamondbacks' 4-3 win over the Dodgers on Tuesday.

Walker joined the Diamondbacks nearly a month ago following a stay at Triple-A Reno, but he has been limited to just one start and 14 total at-bats during his time with the big club. As he displayed with Tuesday's home run off Clayton Kershaw -- which measured an estimated 479 feet, according to Statcast -- and throughout his 2017 campaign at Reno, Walker boasts impressive power, but his swing-and-miss ways and lack of defensive flexibility seem likely to limit him to a bench role so long as he sticks around in Arizona. It would probably take a injury to Paul Goldschmidt before Walker receives a longer look.
