Stewart, who batted .289/.320/.340 in 172 plate appearances in 2015, will again serve as Francisco Cervelli's backup behind the plate, the Pittsburgh Tribune-Review reports.

EDGE Analysis

Fresh off signing a two-year contract, Stewart has hit for a decent average but offers little in the way of power or speed. His biggest contribution may actually come as starter Gerrit Cole's catcher. Cole went 12-4 with a 2.24 ERA when Stewart caught and 7-5 with a 3.59 under Cervelli's guidance.

Stewart agreed to a two-year deal with the Pirates on Thursday.

EDGE Analysis

Despite his age (33), Stewart remains arbitration-eligible, and now will stay with the club through the 2017 campaign. The veteran backstop has posted two straight solid seasons at the dish, and will look to keep things rolling in 2016 in a limited role behind Francisco Cervelli.

Stewart went 3-for-4 with three RBI against the Brewers on Friday.

EDGE Analysis

The big night gave Stewart a .294 batting average in 143 at-bats, matching his 2014 mark. Stewart has caught 336 innings, giving starter Francisco Cervelli (931 innings) a capable backup. That said, Stewart is still looking for his first homer since 2013 and holds just a .669 OPS.

Getting the start with Francisco Cervelli DHing, Stewart went 3-for-7 with a run scored Tuesday. The backup catcher has handled the bat well this season in limited action, posting a .288 batting average in 87 at-bats this season. He's still firmly behind Cervelli on the depth chart.

Stewart started behind the plate on Sunday and went 1-for-4 with a pair of RBI in a Pirates win. Stewart was activated from the disabled list on Friday and was able to produce in his first start of the season on Sunday as he spelled starting catcher Francisco Cervelli. There is nothing to suggest that Cervelli is in danger of losing his starting gig at the moment, but Stewart was able to surpass his RBI total on the season with one swing of the bat. Cervelli will likely remain the starter for now but Stewart certainly has the potential to earn a bigger piece of this timeshare.

It is unclear exactly how many appearances Stewart will have before being activated from the disabled list. Stewart had one rehab assignment with Double-A Altoona on Thursday.

Stewart (hamstring) will begin a rehab assignment with Double-A Altoona on Thursday, Rob Biertempfel of the Pittsburgh Tribune-Review reports. It's not clear how many rehab games Stewart will need before being activated from the disabled list, but he should be ready for big league action at some point in the next week or two. When he is ready to go, Stewart will likely replace Tony Sanchez as the backup catcher behind Francisco Cervelli.

Stewart (hamstring) was placed on the 15-day DL on Sunday, MLB.com reports. Stewart is currently seeing work in the minors while rehabbing a right hamstring strain. When he's ready, he'll challenge Tony Sanchez for the role of primary backup to Francisco Cervelli.
