FORT MYERS, Fla. -- Rays manager Kevin Cash had a front-row seat to Tyler Glasnow’s second live batting practice of the spring on Saturday, and he was blown away by what he saw.

“Filthy,” Cash said of Glasnow’s session. “It was impressive to watch. We sit behind the screen so many times, but I actually sat there and there was no screen, so I sat in the front row. That’s fun to watch from those seats.”

Glasnow threw 25 pitches on Saturday, separated into two sessions to simulate innings. The right-hander threw 15 pitches, watched Chaz Roe pitch, then threw 10 more pitches to finish the live BP. Both Glasnow and Roe pitched to catchers Rene Pinto and Brett Sullivan.

Cash said Glasnow threw his four-seamer, curveball and the changeup he has been working on during the spring. He threw the change 3.5 percent of the time last season but went away from it toward the end of the season after it caused some discomfort in his forearm. But now that Glasnow has made the necessary mechanical adjustments with the pitch, he’s looking to incorporate it into his repertoire.

“He got a couple of soft ground balls on [the changeup],” Cash said. “Every changeup he threw, from my vantage point, was good down in the zone, and [he] didn’t leave anything up in the zone. Landed the breaking ball and also buried it a couple of times. The fastball, I don’t know what the velo was, but it was hard.”

Roe also threw his second live bullpen session and continued his impressive spring after undergoing offseason left knee surgery. The reliever threw 10-15 pitches on Saturday, according to Cash.

McKay update
Brendan McKay (left shoulder stiffness) said he came in feeling “really good” after throwing from 120 feet on Friday. McKay, who was shut down from throwing on Tuesday and Wednesday, is tentatively scheduled to throw a bullpen session on Sunday.

If that goes well, McKay could throw his first live batting practice session during the week, though that’s still unclear.

“It was kind of the same thing I had at the end of the year last year,” McKay said. “Throughout the offseason, it really wasn’t there, and then [it] just kind of popped back up with the intensity and a lot more throwing. Now that we got it all situated, I feel good about it.”

Grapefruit League notes
Randy Arozarena, Ronaldo Hernandez, Jalen Beeks and Trevor Richards were among the standouts in the Rays’ 4-3 loss to the Red Sox in the Grapefruit League opener on Saturday.

Arozarena went 1-for-1 with a double in the ninth that nearly cleared the Green Monster replica in left field. Arozarena then showed off his speed, scoring on Hernandez's single.

“He smoked that ball,” Cash said about Arozarena. “We knew that he really came on offensively at the end of last year and did some good things. You don’t see that in batting practice, everybody does it in BP, but to get out in a game like that and put a charge on the ball, it was impressive.”

Beeks tossed a scoreless second inning and showed off an impressive changeup. Beeks threw 10 pitches, including four changeups.

“Felt good,” Beeks said after the outing. “Always good to get feedback from our hitters, but to get out in a game, it’s always good to see what it looks like and how everything feels. I’ve been working on stuff over the offseason, so it was good. Just want to throw strikes.”
