Lamb said he's no longer feeling pain in his injured left quadriceps and has performed light straight-ahead running drills, Nick Piecoro of the Arizona Republic reports.

EDGE Analysis

Lamb said he was feeling pain up until a few days ago and has increased his activity in recent days. The injured infielder has maintained his timing at the plate by hitting off a high-velocity pitching machine. He still needs to increase the intensity of his running and execute quick cuts before beginning a rehab assignment. Lamb's return will present a challenge for manager Torey Lovullo, who will have to find time for Lamb, Christian Walker, Eduardo Escobar and Wilmer Flores in a crowded infield. "If they're getting a day off every 10 days right now -- I don't know exactly what it is; it's roughly that -- and instead they're getting a day off every seven days," Lovullo said, "I don't think it will be that big of a difference."

Lamb (quadriceps) took batting practice and participated in light throwing Thursday, Michelle Gardner of the Arizona Republic reports.

EDGE Analysis

There hasn't been much to report about Lamb, who was placed on the injured list April 5 with a Grade 2 strain of his left quad muscle. He was given a six-week timetable at that time is on schedule, per manager Torey Lovullo. "He's in that final phase where he's pushing in the right direction," the manager said.

Lamb played catch and hit off a tee Saturday for the first time since sustaining a quadriceps injury, Richard Morin of the Arizona Republic reports.

EDGE Analysis

Lamb is still about a month away from returning. At the time of his injury, backup first baseman Christian Walker was hitting a ton and had the Diamondbacks devising ways to get his bat in the lineup. Since then, Walker has cooled off (2-for-28), so Lamb may have unfettered access to first base when returns mid-May.

Lamb is out for around six weeks with a Grade 2 left quadriceps strain, Jack Magruder of The Sports Xchange reports.

EDGE Analysis

A shoulder injury cut Lamb's 2018 campaign short in late July, and he didn't last long this season before getting injured again. Christian Walker should fill an everyday role at first base until Lamb returns in mid-May.

Lamb was placed on the 10-day injured list Friday with a left quad strain.

EDGE Analysis

Lamb was held out of the Friday's lineup after he pulled up running into second base during Wednesday's game. The 28-year-old underwent an MRI on Thursday, although the severity of the injury remains unclear. The move is retroactive to Thursday, so Lamb will be eligible to return from the injured list April 14 against the Padres. Christian Walker should see an increased role at first base in his absence.

Lamb (quad) is not starting Friday against the Red Sox.

EDGE Analysis

Lamb suffered a left quad strain in Wednesday's game against the Padres. The severity of the injury is not yet clear, but it's bad enough that he'll miss at least one game. Christian Walker starts at first base in his absence.

Lamb was diagnosed with a left quad strain and will undergo an MRI on Thursday, Zach Buchanan of The Athletic reports.

EDGE Analysis

Lamb injured himself running to second base in Wednesday's loss to the Padres and will head for additional tests to determine the severity of the issue. Should he require a trip to the IL, Christian Walker would likely step into a more prominent role at first base.

Lamb was removed from Wednesday's game with an apparent left leg injury, Steve Gilbert of MLB.com reports.

EDGE Analysis

Lamb pulled up lame running to second base in the ninth inning Wednesday. While he was able to walk off under his own power, the corner infielder was clearly favoring his right leg. Lamb will likely head for more tests but should be considered day-to-day for now. Prior to exiting, he was 2-for-4 with a double and RBI.

Lamb informed manager Torey Lovullo that he's ready to play third base if needed, Steve Gilbert of MLB.com reports.

EDGE Analysis

Lamb took fielding practice at the hot corner Monday, and it didn't take long for the former third baseman to re-acclimate to the position. Lovullo said Lamb will play third "sooner than later" and added that he expects Lamb to get 450-500 at-bats in 2019. Lamb entered spring training as the putative everyday first baseman, but Christian Walker's hot spring altered the Diamondbacks' plan.

Lamb is not in the lineup Tuesday against the Padres.

EDGE Analysis

Lamb remains locked in a platoon role at first base with Christian Walker. Walker starts Tuesday with lefty Eric Lauer on the mound.
