Wagner to undergo Tommy John surgery

TORONTO -- Right-hander Neil Wagner is scheduled to undergo Tommy John surgery next week and likely will miss the next 12 months.

Wagner had been dealing with a forearm injury for most of the season but initially hoped to avoid surgery. He missed two months and eventually made one rehab appearance for Bluefield in the Rookie League before shutting things down for good.

The 30-year-old will have the surgery performed by Dr. James Andrews on Aug. 19. There's a chance he could return at some point late next year but will face an uphill battle to get back to the big leagues before 2016.

Wagner last pitched for the Blue Jays on May 14 when he threw 46 pitches over 1 1/3 innings in a lopsided loss to the Indians. He was optioned to the Minor Leagues after the game and made four appearances with Buffalo before he was shut down.

The native of Minnesota was an intergral part of the Blue Jays bullpen in 2013. He posted a 3.79 ERA with 33 strikeouts over 38 innings but lost his spot on the roster this year because he had Minor League options remaining and other relievers did not.

Lind activated; Encarnacion nears return

SEATTLE -- Adam Lind made his long-awaited return to the Blue Jays' lineup in a 6-3 loss to the Mariners on Tuesday night.

Lind was activated from the 15-day disabled list prior to the game and went 0-for-3 with a strikeout. He took the spot of left-hander Brad Mills, who was designated for assignment after Monday's 11-1 loss to the Mariners.

The addition of Lind provides a much-needed upgrade to the heart of Toronto's lineup and the equally positive news is that Edwin Encarnacion should also be back from the DL this week.

"I'm excited to get back and just make this transition as smooth as possible," said Lind, who missed approximately five weeks with a fractured right foot. "They've been doing fine without me, so hopefully I can add a little bit here and there and hopefully contribute to some more wins. Everything is all go, this time of year, in this situation, it's time."

Lind was originally expected to make his return a couple of days earlier but he suffered a minor setback last week in Florida. Lind felt some discomfort in his back after a rehab game with the Gulf Cost League Blue Jays and took the next day off as a precaution.

Back injuries have plagued Lind for the past several seasons and forced him to miss 20 games earlier this year. Any time there's tightness in that area it raises some red flags.

"It was a little worrying because it was in a different spot," Lind said. "When I finished playing a month ago, my lower back was hurting because I was limping for three weeks. It wasn't just my foot that hurt, my lower back hurt as well.

"I started playing again and it came back so I had to do some other treatments and that loosened it up and I think it just flared up another part of the back. But now I'm good to go."

Encarnacion remains on schedule in his return from a strained right quadriceps muscle. The veteran first baseman started a rehab game for Triple-A Buffalo on Tuesday night and hit a first-pitch grand slam during his second at-bat. Encarnacion is expected to be activated for Friday's game against the White Sox.
