Tampa Bay Rays ace Tyler Glasnow believes something wasn't right Friday when the Toronto Blue Jays roughed him up in his most recent start.

"I don't know; I definitely think about it," said Glasnow, according to Marc Topkin of the Tampa Bay Times. "I'm not quite sure. I think you'd have to ask the Blue Jays what was going on. It was definitely a weird start for me. It was definitely strange. I think I had some decent swing-and-miss stuff. I think that the takes were different."

Glasnow, who's been one of the best pitchers in baseball during the 2021 campaign, surrendered a season-high nine hits and five earned runs over 4 2/3 innings. He collected just two strikeouts despite having a 12.6 K/9 through 10 starts this year.

Rays manager Kevin Cash said Glasnow wasn't tipping his pitches.

"We know that the Blue Jays are a talented group of hitters," said Cash. "They've had a track record of not striking out, not a ton of swing-and-miss. Generally speaking, Glasnow ... can bring the worst out in teams that he faces because his stuff is so nasty.

"But for whatever reason on that night, they seemed to be seeing him pretty well."

Glasnow has pitched well against every club except Toronto this season. The 27-year-old owns an 8.44 ERA with a 1.59 WHIP over 10 2/3 innings (two starts) against the Blue Jays, allowing them to hit .311 with a 1.021 OPS against him.
