Jansen will open the season with Triple-A Buffalo.

EDGE Analysis

Jansen reached the Triple-A level for the first time last year, hitting .328/.423/.552 in 21 games. Russell Martin is entrenched as the starter in Toronto and is unlikely to yield that position until he becomes a free agent after the 2019 season, but he's 35, so there's certainly the risk than an injury could open up playing time for Jansen this season. The biggest threat to Jansen's value might be his fellow Triple-A backstop, Reese McGuire. McGuire has a strong defensive reputation and had a solid season at the plate last year as well, hitting .278/.366/.492 in 34 games for Double-A New Hampshire.

Jansen struck out the side around one hit in a scoreless inning of work to earn his first save of the season Sunday against the Giants.

EDGE Analysis

Jansen required 23 pitches to retire the side, but he did so in overpowering fashion en route to his first save of the season. The big right-hander didn't quite look himself over his first three appearances, racking up an ERA of 12.00 and a WHIP of 2.00, but Sunday's effort was a big improvement. Jansen is considered to be 100 percent healthy and seems to be rounding into form after his early struggles.

Jansen was optioned to Triple-A Buffalo on Tuesday, Ben Nicholson-Smith of Sportsnet.ca reports.

EDGE Analysis

Jansen is a promising catching prospect, though he was always unlikely to open the season with the big-league club. Still just 22, he hit well at the three highest levels of the minors last season (a combined .323/.400/.484 in 104 games) but only has 21 games at Triple-A. With strong performances in his return to Buffalo this season, Jansen could receive his major-league debut later this year.

Jansen was added to Toronto's 40-man roster and is protected from the Rule 5 draft.

EDGE Analysis

The 22-year-old catcher reached Triple-A Buffalo last season. Although he played just 31 games with Buffalo, Jansen managed to make an impact at the plate. He posted a great .328/.423/.552 line and drew 11 walks while striking out just seven times. While the Blue Jays may want him to spend some more time with Buffalo to start the 2018 campaign, Toronto will have a hard time keeping him in the minors if he continues dominating at the plate.

Jansen, who ascended from High- to Triple-A during the 2017 season, finished the campaign with a .323/.400/.484 slash line over 104 total games.

EDGE Analysis

The catching prospect logged 31 games at High-A, 52 contests at Double-A and 21 affairs at Triple-A. Overall, he popped 10 home runs, notched 48 RBI and scored 50 times. Jansen's jump through the ranks was obviously impressive, but the 22-year-old's plate discipline (1.02 BB/K) was equally noteworthy. Toronto's 16th-round selection in 2013 has thrust himself into a tight race with Max Pentecost for the Jays' heir apparent to Russell Martin.

Jansen attributes his breakout campaign in the farm system to a new approach at the plate, and better vision since getting eye glasses in the offseason, Kristina Rutherford of Sportsnet.ca reports.

EDGE Analysis

Jansen began 2017 at High-A Dunedin, but as September nears, the 22-year-old sits one step away from the big leagues. The backstop suggested his current campaign is not a flash-in-the-pan, as tangible changes have made a positive impact that can last. "The last two years I was trying to be something I'm not," he said. Jansen's new approach has propelled him to a .341/.418/.516 slash line over 95 minor-league games this season. Additionally, he started wearing glasses -- both on and off the field -- for the first time, and the top prospect said the improved sight is "absolutely" helping him at the plate.

Jansen, who began the season with High-A Dunedin, was promoted Thursday for the second time in 2017 and joined Triple-A Buffalo, Ricardo Arguello of USA Today Network reports.

EDGE Analysis

Jansen, a 22-year-old backstop, is arguably the organization's breakthrough player of the year. He hit .369 with a .963 OPS through 31 games with Dunedin, then slashed .291/.378/.419 over 52 contests at Double-A New Hampshire. Jansen has unexpectedly emerged as the Jays' top catching prospect with an outstanding campaign, and his efforts will likely land him an invite to next year's spring training.
