Jansen spent the offseason developing a pre-game hitting routine to help him maintain a consistent swing plane and spot flaws in his mechanics, Gregor Chisholm of The Toronto Star reports.

EDGE Analysis

The 24-year-old came up through the minors with a reputation as a bat-first catcher, but he spent last season focused on improving his defense and pitch framing, and his .639 OPS reflected the lack of attention he was giving that side of his game. Jansen now hits a weighted ball off a tee as part of his pre-game preparations. "I've always taken hitting very seriously, but I've always felt like I just didn't need tee work," Jansen said Tuesday morning. "I just wanted to get my timing down, that was the most important thing for me, until I went into this off-season and developed. I like to hit off a tee now, I actually want to, and I need it. I'm starting to understand my body more and my swing." He posted a .275/.390/.473 slash line through 88 games for Triple-A Buffalo in 2018, and a return to something close to that level of production would be a huge boost for the Jays, as well as likely allowing Jansen to seize the No. 1 job behind the plate for Toronto rather than working in a timeshare with Reese McGuire.

Jansen isn't in the starting lineup for Tuesday's game against the Red Sox.

EDGE Analysis

Jansen is not in the lineup Tuesday against Atlanta.

EDGE Analysis

Jansen sits for the third time in the last five games. It wouldn't be a surprise to see him on the bench fairly frequently down the stretch, as he's hit just .208/.280/.366 this season. Beau Taylor will catch Tuesday.

Jansen is out of the lineup for Sunday's game against the Astros.

EDGE Analysis

The Blue Jays will alternate starts between their top two backstops for a fifth consecutive game, with Reese McGuire getting the nod behind the dish in the series finale. Jansen wrapped up August with a 1-for-4 showing in Saturday's 6-4 win, bringing his monthly average to .245.

Jansen is out of the lineup for Sunday's game against the Mariners, Greg Johns of MLB.com reports.

EDGE Analysis

Reese McGuire gets another turn behind the dish while Jansen rests in the series finale. Jansen has gone hitless in 11 at-bats over his last four games, which has hurt his case for gaining hold of a larger portion of the timeshare at catcher.

Jansen isn't in the starting lineup for Friday's game against the Mariners.

EDGE Analysis

Jansen is 0-for-9 at the dish over his last three contests, so he'll take a seat for Friday's series opener. Reese McGuire will handle the catching duties and hit ninth with Jansen out of the mix.
