Arenado went 3-for-4 with a double and an RBI in Saturday's 5-4 win over the Royals.

Arenado's bat has been hot in August -- he's gone 15-for-42 (.357) during his 10-game hitting streak that spans the whole month. The third baseman had slumped briefly in late July, but he's back up to a .287/.335/.511 slash line with 24 home runs, 82 RBI, 56 runs scored, two stolen bases, 22 doubles and two triples through 112 contests this season.

Urias is not in the starting lineup Saturday versus the Mariners, Rich Dubroff of BaltimoreBaseball.com reports.

Urias will get a day off after he went 2-for-7 with a triple and a run scored while starting the last two games following a one-game absence with a heel injury. Jordan Westburg will take over at third base and bat eighth against Seattle.

Henderson is not in the starting lineup Saturday against the Mariners, Rich Dubroff of BaltimoreBaseball.com reports.

Henderson will take a seat after he went 0-for-4 with two strikeouts during the series opener Friday. Jorge Mateo will draw the start at shortstop and bat ninth versus Seattle.

Garcia (upper body) will be on the bench for Saturday's game against the Cardinals.

Garcia left Friday's game against the Cardinals with upper-body discomfort, and he'll remain sidelined Saturday. The exact nature and severity of his injury remain unclear, but the Royals have an off day scheduled for Sunday, so he'll get at least two days to rest. Matt Duffy will handle third base in his absence.

Peterson isn't in the Diamondbacks' lineup Saturday against the Padres, Jeff Sanders of The San Diego Union-Tribune reports.

Left-hander Rich Hill will take the mound for San Diego, forcing the lefty-hitting Peterson to the bench for the start of Saturday's game. Buddy Kennedy will start at third base and bat sixth while Peterson sits.

Perez signed a minor-league contract with the Pirates on Friday.

The 23-year-old third baseman was dumped from Houston's 40-man roster and ultimately released a week later, but he quickly caught on with a new organization. Perez is expected to report to Triple-A Indianapolis and should handle a near-everyday role with the Pirates' top affiliate. Perez slashed .255/.328/.399 with 10 home runs and three stolen bases in 357 plate appearances at Triple-A Sugar Land this season prior to his release.

The Diamondbacks selected Kennedy's contract from Triple-A Reno on Saturday.

Kennedy has enjoyed a breakout season in Triple-A this year, slashing .318/.447/.480 with 46 RBI through 407 plate appearances with Reno. He played 30 games with the D-backs last season with limited success and figures to act as an infield depth piece while in the majors. To make room for Kennedy on the active roster, Emmanuel Rivera was optioned to Triple-A and Kristian Robinson was designated for assignment.

The Diamondbacks optioned Rivera to Triple-A Reno on Saturday.

Rivera hasn't recorded a hit since the end of July, so he'll head back to the minors in order to right the ship. Rivera has had better luck in Triple-A this season, slashing .348/.378/.591 in 74 plate appearances, so he could make a quick return to Arizona if he gets going at the plate again. Buddy Kennedy was selected from Reno to take Rivera's spot on the active roster.

LeMahieu (calf) remains absent from the lineup ahead of Saturday's game against the Marlins.

LeMahieu hasn't played since Monday while dealing with a sore right calf. A trip to the injured list appears unlikely, Gary Phillips of the New York Daily News reports, as the veteran took grounders at third base prior to Saturday's game and appears to be working toward his return. Isiah Kiner-Falefa remains the starting third baseman for now.

Duffy went 1-for-3 with two RBI in Friday's 12-8 win over the Cardinals.

Duffy didn't start the game, but he checked in at third base after Maikel Garcia (upper body) exited. After starting the year fairly well in a limited role, Duffy has been pretty quiet, batting .218 with a .530 OPS over 33 games since the start of June. He's at a .260/.314/.322 slash line with a home run, 10 RBI, 12 runs scored and six doubles through 159 plate appearances overall. If Garcia ends up on the injured list, Duffy or Matt Beaty would be most likely to pick up additional time at the hot corner.
