JUPITER, Fla. -- It came in front of far fewer eyes than Lance Lynn's Grapefruit League start against Houston, but Trevor Rosenthal and Luke Weaver also took the mound on Thursday in what represented an encouraging step forward for both.
The two right-handers, both of whom were set back by minor injuries earlier this month, threw morning bullpen sessions. Each got through their work without issue.

"This is just a major hurdle to get them out here," manager Mike Matheny said.
Weaver faced two batters in a March 1 appearance before exiting due to lower back tightness. He hasn't pitched in a game since, and that has precluded Weaver from furthering his case as a rotation candidate.

Rosenthal made two relief appearances before being scratched from his scheduled start on Monday due to tightness around his right latissimi dorsi (lat) muscle. An MRI showed no evidence of a tear in that area, and Rosenthal was cleared to resume throwing.
Of the two, Matheny indicated that Weaver is closest to returning to game action. Weaver is optimistic that he'll be pitching in a Grapefruit League game as early as this weekend.
"Every day has gotten better," Weaver said. "Today is that it-better-all-come-together day. That's where I'm at right now."
Rosenthal, Matheny said, will need to throw on the side at least one more time before he's considered game ready.
Odds and ends
• Matheny said the Cardinals are expecting Seunghwan Oh back in camp on Monday now that his World Baseball Classic stint is over. Oh appeared in Korea's final game on Thursday and earned the win with two scoreless innings. Over the three games, Oh struck out six and did not allow a hit in 3 1/3 innings.
• Tyler Lyons threw live batting practice on Wednesday as he continues to heal from November knee surgery. Lyons is likely to throw at least one more live batting practice session before being considered for a game appearance, Matheny said.
