Loup was officially promoted on Thursday, following a strong first half of the season with Double-A New Hampshire. He headed north to fill the spot of reliable Luis Perez, who was placed on the 60-day disabled list with an injured left elbow that likely will require Tommy John surgery.
The 24-year-old Loup was keeping a close eye on the Blue Jays' recent injury woes and had a feeling his time in the big leagues might be coming in the near future.
"Kind of surprised, but kind of not surprised because unfortunately Luis went down, so I just kind of thought I might have had a slight chance," said Loup, who posted a 2.78 ERA in 37 games for New Hampshire.
"Then, they called me in yesterday right when I got back from the [Double-A] All-Star Game and told me I was coming up. A little, yeah shocked, excited, but overall ready to go."
Loup is set to become the 26th different pitcher the Blue Jays have used this season. He has been in Toronto's Minor League system since being taken in the ninth round of the 2009 First-Year Player Draft.
The native of Louisiana has spent a couple of years tinkering with the angle of his arm slot when releasing the ball, but believes he has now found what will make him effective.
"When I got drafted, I was kind of a mid-three quarters and then they raised me up and that didn't go so well," Loup said. "Then they just dropped me back down and ever since then, that's where it has been.
"I'm probably more sidearm now, lower three-quarters sidearm, whereas before I was probably mid-to-high three quarters, so a little bit lower than I was."
Toronto manager John Farrell said he felt the lower arm slot has added more of a sweeping action to his breaking ball against left-handed hitters. That has the Blue Jays projecting him as a situational lefty to use in the middle innings.
