Tristan Beck undergoes vascular surgery for an aneurysm in his upper arm, leading to an eight-week recovery period.

Prospects like Kai-Wei Teng and Trevor McDonald may not provide enough depth, potentially prompting the team to pursue free-agent options like Jordan Montgomery and Michael Lorenzen to strengthen their pitching staff before the season begins.
