Bart (thumb) was spotted playing catch on the field Monday, Andrew Destin of the Pittsburgh Post-Gazette reports.

EDGE Analysis

The right-handed Bart is on the injured list with a Grade 1 sprain of his left thumb. Though he wasn't wearing his full catching gear Monday, the fact that he had a baseball glove on his injured hand would seem to indicate that the sprained thumb has healed on some level. The Pirates will likely wait and see how Bart responds to additional baseball activities before sending him out on a minor-league rehab assignment.

Bart (thumb) was placed on the 10-day injured list Tuesday, Kevin Gorman of TribLive.com reports.

EDGE Analysis

The 27-year-old was lifted from Sunday's matchup against Atlanta due to the injury and will now be sidelined for at least the next week and a half, though the severity of the injury remains unclear. Grant Koch was called up from Triple-A Indianapolis and will serve as Yasmani Grandal's backup while Bart is unavailable.

Bart left Sunday's game against Atlanta due to a left thumb injury, Alex Stumpf of MLB.com reports.

EDGE Analysis

Bart was pulled before the start of the second inning Sunday, with Yasmani Grandal taking over behind the plate. The severity of the injury is not yet known, but Bart is being evaluated by medical staff, per Noah Hiles of the Pittsburgh Post-Gazette. Bart has gone 9-for-28 with one home run and four RBI in May.

Bart went 2-for-4 with a double and a grand slam in Thursday's 7-6 loss to the Giants.

EDGE Analysis

Bart made quite an impression on his former team, launching a 434-foot grand slam off Mason Black in the fourth inning to put the Pirates ahead 5-1. The 27-year-old Bart's been hot of late, going 9-for-23 (.391) with three extra-base hits in his last seven games on the heels of an 0-for-14 stretch. Overall, he's slashing .267/.362/.517 with four homers, 12 RBI and seven runs scored across 21 games. With Yasmani Grandal nursing a groin injury, Bart could be in line for a regular starting role in the short term.

Bart is out of the lineup for Sunday's game against the Rockies.

EDGE Analysis

Though he stuck around over Henry Davis -- who was optioned to Triple-A Indianapolis on Friday -- once Yasmani Grandal (foot) was activated from the 10-day injured list, Bart looks as though he'll operate as the Pirates' No. 2 option behind the plate. He'll take a seat for the second straight day while Grandal logs another start at catcher.

Bart is out of the lineup for Wednesday's game against the Athletics.

EDGE Analysis

Bart appears to have wrested the No. 1 catching job away from Henry Davis, but the former will hit the bench for Wednesday's day game after spending eight innings behind the dish in a 5-2 loss Tuesday night. Davis will draw the start Wednesday, but he could be headed to Triple-A Indianapolis if Yasmani Grandal (foot) is reinstated from the 10-day injured list this weekend.

Bart went 1-for-4 with a three-run homer and two runs scored in Thursday's loss to the Brewers while also drawing a walk.

EDGE Analysis

Bart put the Pirates ahead with a three-run shot in the bottom of the first inning, giving the catcher his third home run in just seven games this season. He also drew a two-out walk in the fifth before coming around to score the tying run on a Jack Suwinski double, marking Bart's first game this season with two runs scored. The backstop has hit safely in six of his seven games and continues to make a strong case for more playing time with Henry Davis scuffling at the plate and Yasmani Grandal (foot) still on the 10-day injured list.

Bart will start at catcher and bat cleanup Thursday against the Brewers.

EDGE Analysis

Bart has been included in the lineup in four of the past six games and appears to have surpassed Henry Davis on the depth chart at catcher. The eventual return of Yasmani Grandal (foot) from the 10-day injured list could cost Bart some playing time, but for now, the 27-year-old should garner the lion's share of starts behind the dish while he's swinging a hot bat. Bart heads into Thursday's game with a 1.119 OPS over 23 plate appearances on the season.

Bart (head) is starting at catcher and batting fifth in Saturday's game against the Red Sox.

EDGE Analysis

Bart was slated to start Wednesday against the Mets, but he was scratched from the lineup late while dealing with concussion symptoms after being hit in the head by a ball during batting practice a few days prior. Having evidently checked out OK, Bart will draw the start against Boston right-hander Kutter Crawford while Henry Davis gets a rest.

Pirates manager Derek Shelton said Bart was scratched from the lineup ahead of Wednesday's 9-1 loss to the Mets after the catcher wasn't feeling well leading up to game time, Noah Hiles of the Pittsburgh Post-Gazette reports.

EDGE Analysis

While elaborating on the matter, Shelton noted that Bart was hit in the head by a ball during batting practice a few days ago, but the Pirates had fully expected the 27-year-old to be ready to catch for Wednesday's series finale. However, in light of Bart being scratched prior to first pitch a few days after taking the hit to the head, it's possible that the catcher is dealing with symptoms of a concussion. The Pirates haven't explicitly said that Bart is in concussion protocol at this time, so he'll be considered day-to-day heading into this weekend's three-game series with the Red Sox.
